A flow meter is a device used to measure the volume or mass of a gas or liquid. You may have heard a flow meter be referred to by many different names such as; flow gauge, liquid meter and flow rate sensor. This can be depending on the industry they are used in. However, the most important element of flow meters is the accuracy of their measurements.   Inaccurate flow measurement can have a number of adverse effects such as;   Poor flow and related controls Bad quality products Incorrect fiscal and allocation measurement Creating an unsafe environment for workers. Can create flow disturbances   What can cause inaccurate flow meter measurements?     A change in process conditions. A change in temperature, pressure, viscosity, flow rates and fluids can cause inaccurate flow measurements. For example, in gas flow measurement a change in temperature can change the density of the gas which as a result can lead to an inaccurate reading.   Choosing the wrong flow meter Wrong flowmeter selection is one of the major causes of inaccurate flow measurement.There is no “one size fits all” when it comes to choosing a flow meter. It is really important to take into account a few considerations before choosing a flow meter. Choosing the wrong flow meter can result in a huge cost in the amount of production time lost.   Placing price at the top of your criteria That bargain flow meter can quickly turn into a costly nightmare. Be aware of relying on cost and popularity when it comes to choosing your flow meter. If you choose the “cheapest option” it will be easier to get the wrong flow meter which does not suit your requirements physically or performance-wise.   How can you improve the accuracy of your flow meter?   Here’s a tip from a Siemens flow specialist that may help you with the accuracy of your flow meter. When discussing the sizing of magnetic flow meters to the application, there are two rules to follow: Rule number one: Never size the meter to the pipe. Always size it to the flow rates. Rule number two: Refer back to rule number one. For example, a recent customer complained about the accuracy of his magnetic flow meter. After we investigated this it turned out that the meters installed were oversized for the flow rates. This meant that the sensors reading were at the very bottom of the operating scale. The first step is to understand the right way to size a meter. A good rule of thumb is to size the meter so the average flow is around 15 to 25% of the maximum flow capacity of the meter.   Here is an example…   A meter has a maximum flow rate of 4000 GPM, the average flow should not be less than 500 to 1000 GPM. This flow rate will maintain sufficient velocity through the meter, giving the customer room for expansion. Many installations are designed for expansion in the future, so large size pipes are installed to accommodate for this. In this case, you must look at the minimum flow expected. You must ensure that the average flow should never fall below 2 ft/s or in this case 300 GPM If it is not possible to reduce the overall size of the pipe to accommodate the proper size flow meter, you should install a reducer in the line. This should be located about 3 diameters upstream of the flow meter. You can then install an expander downstream and return to the original pipe size. This process will prevent inaccurate flow measurement and still allows you to remove the small meter in the future if needed. We stock a comprehensive range of flow meters to suit all media, including Clamp On, Coriolis Mass, Electromagnetic, Liquid, Mass, Paddle Wheel, Positive Displacement, Ultrasonic, Variable Area and models.

It can often seem a bit of a minefield when it comes to maintaining safety and efficiency in an industrial environment. However, pressure relief valves are the unsung heroes of this area. These valves prevent overpressure situations and play a vital role in protecting equipment. However, it is not uncommon for a common question to arise: how often should pressure relief valves be tested and replaced in the UK? At Fluid Controls, we thought we'd collate this useful article to answer this common FAQ in more detail. As a distributor of pressure control products, we know and understand the importance of striking the right balance between compliance, safety and cost-effectiveness, so read on and let us impart our wisdom on you!   What role do pressure relief valves play?   Within industries, pressure relief valves are considered to be guardians of pressure-sensitive systems. They are commonly found in a wide range of processes and equipment, from boilers and pressure vessels to pipelines and hydraulic systems. Pressure relief valves automatically release excess pressure to ensure that the internal pressure within the system remains within safe limits. Through this release of pressure, they prevent disastrous failures, explosions, and other hazardous situations that could potentially lead to injury, damage to property, and/or environmental harm.   The importance of regular checks   Just as the tires on your car require regular checks to ensure they are inflated to the right level and have a decent amount of road grip, pressure relief valves require frequent checks to ensure they are functioning correctly when the pressure’s on. Regular checks serve several important purposes: Ensuring safety: Testing pressure relief valves on a regular basis provides the assurance that these valves are ready to perform their critical task when needed. It’s like having a fire extinguisher that you know will work in the event of a fire. Regulation compliances: In the UK, industrial safety regulations set standards for the maintenance and testing of pressure relief valves. Adhering to these regulations not only keeps your facility compliant but also demonstrates your commitment to safety. Preventing downtime: A malfunctioning pressure relief valve can lead to equipment breakdowns and unplanned downtime. Regular testing helps identify issues before they escalate, minimising disruptions to operations.   How often should pressure relief valves be tested?   The frequency of pressure relief valve testing depends on a few factors and are often tailored to your specific application. The key considerations are: Manufacturer recommendations: As with any equipment, the manufacturer of your pressure relief valve will provide guidelines for testing. These recommendations are rooted in the valve’s design, intended usage, and expected wear and tear. Industry regulations: Different industries may have distinct requirements. For example, the Health and Safety Executive (HSE) in the UK provides guidelines for specific sectors. It’s crucial to stay informed about the latest regulations that relate to your industry. Risk assessment: Conducting a risk assessment helps you understand the potential consequences of a valve failure. A valve in a high-risk scenario might need more frequent testing compared to a lower-risk situation. Operational history: If a valve has demonstrated recurrent problems in the past, more frequent testing could be necessary. Think of it as a valve’s health checkup or MOT. How Often Do Pressure Relief Valves Need to Be Replaced?   While testing extends the life of your pressure relief valve, like all things, these valves have a certain lifespan. Replacement times are influenced by factors such as: Manufacturer recommendations: Just as a car’s mileage guides oil changes, the manufacturer’s guidelines for valve replacement intervals provide a roadmap for ensuring continued reliability. Deterioration over time: Over time, the materials in pressure relief valves can degrade due to environmental factors, operational stress, and wear. Regular testing can help determine when a valve’s performance is no longer within acceptable limits. Advancements in technology: As technology advances, newer pressure relief valves may offer enhanced safety features and improved efficiency. Considering an upgrade could be a sensible decision to stay ahead in terms of safety and compliance. How often should pressure relief valves be tested and replaced?   As a general rule of thumb, we’d say that pressure relief valves should be tested every 12 months and replacements should take place every 3 to 5 years.   Pressure relief valves from Fluid Controls   We hope this article on testing and replacing pressure relief valves has helped you to better understand the citation and given you some good insights. So, when it comes to the question of how often should pressure relief valves be tested and replaced in the UK, we’d always say as often as necessary to uphold the highest standards of safety and operational excellence. Here at Fluid Controls, we offer relief valves, pressure regulators, and many other valve types for maximum efficiency in your application. We also stock a wide range of flow control and measurement components gauges and sensors.

Valves are small components with big responsibilities. They are linchpins that keep industrial, commercial and residential operations running smoothly and safely in manufacturing, heating, and many other types of systems. Among the various types of valves available, safety valves and relief valves are two of the most important. While they may appear similar at first glance, they have distinct functions, applications, and mechanisms of operation. Understanding the difference between safety valves and relief valves is crucial for ensuring the optimal performance and safety of your systems. Whether you are involved in chemical processing, water treatment, or any other industry that relies on controlled pressure, choosing the right valve is important for both the safety and the efficiency of your system. Let’s discover the difference between a pressure relief valve and a pressure safety valve so you can work out which is right for you.   What Is A Safety Relief Valve?   A safety valve serves as the guardian of a pressurised system, designed to automatically release the pressure created by a gas, steam, or liquid when the pressure within reaches its limit. They are always alert, ready to act the moment things go awry. The primary role of a safety valve is to protect your system from the potentially catastrophic effects of overpressure, which could lead to equipment damage or, worse, safety hazards for personnel. The mechanism within a safety valve is straightforward but effective. It is calibrated to open fully and rapidly divert the flow of the over-pressurised liquid or gas to a safer location, often the surrounding atmosphere. Once the pressure returns to acceptable levels, the valve closes, allowing the system to resume normal operations. This rapid, full-opening action is one of the defining characteristics of a safety valve and sets it apart from other types of valves. Safety valves are commonly found in high-pressure systems such as steam boilers, gas cylinders, and chemical plants. Their role is not just preventive; it’s pivotal for maintaining the integrity and safety of your entire operation.   What Is A Relief Valve?   A relief valve is another critical component in the management of a system’s pressure, but it operates differently from a safety valve. While both types aim to alleviate excessive pressure, a relief valve does so in a more controlled manner. Unlike the rapid, full-opening action of a safety valve, a relief valve opens gradually, allowing a proportional amount of the over-pressurised gas or liquid to escape. This approach makes relief valves ideal for systems where pressure fluctuations are more frequent but less severe. The relief valve is designed to open incrementally as the pressure rises, releasing just enough of the substance to bring the system back to its safe operating level. Once the pressure has been stabilised, the valve closes. This ensures minimal disruption to operations. This variable flow control is a defining feature of relief valves and distinguishes them from their safety valve counterparts. Common applications for relief valves include hydraulic systems, water heating systems, and air compressors. Their role is vital in maintaining the balance of your system, making sure that it operates safely and efficiently.   What Are The Key Differences?   At this point, you might be wondering what is the difference between a pressure relief valve and a pressure safety valve when both serve a similar purpose. While they share the same goal of maintaining safety and operational efficiency, their mechanisms and applications set them apart in distinct ways. One of the most noticeable differences is the opening mechanism, but another key distinction lies in their applications. Safety valves are typically used in high-pressure systems where rapid pressure relief is needed to prevent catastrophic failure. Relief valves, on the other hand, are more suited for low to medium-pressure systems where pressure variations are frequent but not extreme. The flow control in each type of valve varies too. Safety valves operate at a fixed flow rate, meaning they open fully or not at all. Relief valves offer variable flow control, allowing for a more nuanced approach to pressure management. Understanding these key differences can help you make the right choice for your application while ensuring that your system operates safely and efficiently.   What Are Their Similarities?   While safety valves and relief valves have their unique characteristics and applications, they also share some common ground that is worth noting. Both types of valves serve the fundamental purpose of protecting your system from the dangers of overpressure. Whether working with high-pressure steam or hydraulic fluid, these valves act as safeguards to prevent equipment damage and maintain a safe working environment. Another shared feature is their construction. Both valves are often made from similar materials like stainless steel or brass, designed to withstand industrial use. Their construction helps to ensure their long-lasting performance and reliability, making them indispensable components in a pressure control strategy. Both valves are equipped with a set point, a predetermined pressure level at which they activate. This set point is adjustable, allowing the valve’s performance to be tailored to the specific requirements of a system. Despite their differences, the core function of safety and relief valves is the same; to maintain a safe and efficient operating environment. Recognising these similarities can help you appreciate the roles each valve plays in a pressure management system. Selecting the right valve isn’t just about ticking a box; it’s about making an informed decision that aligns with the specific needs and challenges of your system. Whether you are dealing with high-pressure environments or systems with frequent but moderate pressure fluctuations, the choice between a safety valve and a relief valve is a critical one. Both types of valves are indispensable, each offering unique advantages depending on your system’s requirements. When looking at safety vs relief valves, remember that including either or both of them in your system protects your equipment and also contributes to a safer and more efficient working environment.

The use of gases in the semiconductor industry dates back to the early 1950's to 1960's. During the semiconductor manufacturing process, gases are mainly used to clean and protect semiconductor materials to ensure their purity and quality. Among the most commonly used gases are nitrogen and hydrogen. As semiconductor technology developed and manufacturing processes continued to improve, the demand for gases increased. In 1970, further development of semiconductor manufacturing technology, the application of gases in key processes such as etching and deposition of thin films gradually increased, and fluoride gases (e.g. SF6) and oxygen became commonly used etching and deposition gases. 1980 saw a further increase in the demand for gases with the development of integrated circuits and the increase in demand for them. Hydrogen was widely used in the manufacturing process, including hydrogen annealing and hydrogen vapour deposition. And from 1990 to the present, the demand for high-purity gases and specific gases has increased as semiconductor device sizes have continued to shrink and new processes have been introduced. For example, the application of extreme ultraviolet lithography (EUV) requires the use of extremely high-purity gases such as nitrogen and hydrogen. Semiconductor gas continues to increase with the development of related products driven by more and more products are revealed, while the gas also belongs to the source of danger, so the products used for gas decompression, gas detection products and prevent gas leakage products have emerged such as pressure regulators, gas valves, gas pressure gauges, gas leakage detector, etc., and their roles are as follows: Pressure regulators: Pressure regulators are devices used to control gas pressure. They usually consist of a regulator valve and a pressure sensor. Pressure regulators take a high pressure gas input and stabilise the pressure of the output gas by adjusting the valve to meet specific application requirements. Pressure regulators are widely used in areas such as industry, manufacturing and laboratories, as well as in the semiconductor industry, among others, to ensure the stability and safety of the gas supply. Gas Valves: Gas valves are used to control the flow of gases and to close gas passages. They usually have an on/off function that opens or closes the gas flow. There are various types of gas valves, including manual valves, electric valves and pneumatic valves. They are widely used in gas systems to control the flow, pressure and flow rate of gases. Gas Pressure Gauges: Gas pressure gauges are used to measure the pressure level of a gas. They are usually installed at critical locations in gas systems to monitor pressure changes and ensure that they are within safe limits. Gas pressure gauges are widely used in industry, manufacturing and laboratories, and the semiconductor industry has also been involved. Gas Leak Detectors: Gas leak detectors are used to detect leaks in gas systems. They detect the presence of gas leaks and sound an alarm so that timely action can be taken to prevent leakage accidents. Gas Leak Detectors are widely used in industrial, chemical, oil and gas applications, and the semiconductor industry has also been involved.

Semi-automatic switching device is applied to decompression gas supply of double-sided high-pressure gas cylinders to realize continuous gas supply with blowing function by automatic switching, which is widely used in the fields of semiconductors and electronics, medical treatment, gene technology, biopharmaceuticals, scientific research and so on. The automatic switchover is an open disk for the delivery control of common, inert and bulk gases. All centralized gas supply systems are ideally suited for the use of automatic switching panels. An uninterrupted gas supply is absolutely essential in a number of critical manufacturing and laboratory processes. Suspension of the gas supply in any way can result in failed or ruined experiments, loss of productivity and even downtime for the entire facility. Semi-automatic switching systems are able to minimize costly downtime by switching from a primary or backup cylinder without interrupting the gas supply. Once the primary cylinder or bank of cylinders is depleted, the system automatically switches to the backup cylinder or bank of cylinders for continuous gas flow. The user then replaces the air cylinder with a new one while gas still flows from the reserve side. A bi-directional valve is used to indicate the primary or reserve side when changing cylinders. Advantages of semi-automatic switching device 1. Gas can be supplied without interruption Automatic switching of the supply line allows continuous supply of gas for a long period of time, and can be automatic after the line is switched.   2.Compact space design Because various types of equipment and gas cylinders are assembled, the structure is compact and the environmental space utilization is more efficient.   3.Responding to various usage methods Since gas panels and control panels are independent of each other, there is a high degree of expansion to parallel switching type and independent type of operation panel, so it is possible to cope with various methods of use.   4.Slim & Functional Design The semi-automatic switching device has the liquefied gas cylinders side by side in an orderly manner.

As the semiconductor market grows, standards for purity and accuracy become more stringent. One of the determining factors in the quality of semiconductor manufacturing is the gases used in the process. These gases play many roles in the manufacturing process, including:   Precision process control   Contamination prevention   Metallurgical property enhancement   To perform these roles effectively, the gas supply and distribution system must be efficient. The design of gas handling systems used in semiconductor manufacturing must be supported by robust components and customized assemblies to ensure reliable and high quality production of semiconductors. Gases used in semiconductor manufacturing The process of manufacturing semiconductors requires the use of different gases at different stages of the process.   While common gases such as nitrogen, hydrogen, argon and helium can be used in their pure form, certain processes may require specialized mixtures. Silanes or siloxanes, hexafluorides, halides and hydrocarbons are a few of the specialty gases used in semiconductor manufacturing. Many of these gases can be hazardous or highly reactive, creating challenges in the selection and design of components for gas systems.   Here are some examples: Hydrogen and helium can easily leak from piping and fitting systems due to their small atomic size and weight.   Silanes are highly flammable and can spontaneously combust (autoignite) in air.   Nitrogen difluoride used in the deposition, etching and chamber cleaning stages becomes a potent greenhouse gas when leaked into the environment.   Hydrogen fluoride (etching gas) is highly corrosive to metal piping.   Trimethylgallium and ammonia can be difficult to handle - small fluctuations in their temperature and pressure requirements can affect the deposition process.   Controlling process conditions to minimize the negative effects of these gases must be a top priority during system design. It is equally important to use the highest quality components such as AFK diaphragm valves during the build process.   Addressing System Design Challenges   Semiconductor grade gases are in most cases of high purity and provide inert conditions or enhance reactions at different stages of the manufacturing process, such as etch and deposition gases. Leakage or contamination of such gases can have negative effects. Therefore, it is critical for the system components used to be hermetically sealed and corrosion resistant as well as have a smooth surface finish (electrolytic polishing) to ensure that there is no possibility of contamination and that an extremely high level of cleanliness can be maintained. In addition, some of these gases can be heated or cooled to achieve desired process conditions. Well-insulated components ensure temperature control, which is critical for efficient performance of the final product.   From the source inlet to the point of use, AFK's wide range of components support the ultra-high purity, temperature, pressure and flow control required in semiconductor cleanrooms and vacuum chambers.   Designed Systems with Quality Components in Semiconductor Fabs   The role of quality components and design optimization is critical to the precise control and safe manufacture of semiconductors. The components used need to be robust and leak-free to match the varying process conditions required at different stages of manufacturing.AFK's high-quality valves, fittings, regulators, piping, and sealing brackets are characterized by the following features:   Ultra-high purity   Leak-free seals   Temperature controlled insulation   Pressure control   Corrosion resistance   Electrolytic polishing treatment

The different chemicals and gases used in semiconductor manufacturing require robust fluid systems for uninterrupted supply at every stage of production. These fluid systems must be able to support the extreme process conditions required for semiconductor manufacturing while ensuring a clean, leak-free and controlled process. Therefore, the selection of fluid system components is critical in the precision semiconductor manufacturing process. Choosing high quality fluid system components is synonymous with increased manufacturing efficiency and reduced system downtime. With respect to the semiconductor manufacturing process, we will discuss the critical role of fluid system components and the importance of their reliability.   Importance of Fluid System Components in Semiconductor Manufacturing   Fluid system components in semiconductor manufacturing include different chemical mixing, conveying, and control systems for safely transporting chemical fluids in a controlled environment. An ideal fluid system has:   ➢ Uniform chemical mixing   ➢Contamination control   ➢Temperature and pressure control   ➢Uninterrupted chemical supply   Only the highest quality components can provide such ideal conditions in a semiconductor fluid system. The advantages of using such components include: Accurate: Components such as valves, regulators and pumps work in tandem to ensure that the correct proportion of chemical is delivered to the production cell. Precise inputs eliminate the risk of flow variations, which improves the quality of the final product.   Compatibility and cleanliness: Fluid system components with material compositions that are compatible with process fluids reduce the risk of contamination. In addition, the leak-free installation of these fluid system components reduces particulate contaminants, providing a clean and controlled manufacturing environment for improved yields.   Safety: Gases and chemicals used in semiconductor manufacturing can be harmful to human health. However, fluid system components designed to prevent leaks and spills can deliver these fluids to production units in a safe and controlled manner.   Efficiency: The leak-free construction and precise control of high-quality fluid system components minimizes operational downtime and frequent maintenance requirements, promoting smooth, efficient manufacturing to meet production goals.   Quality Manufactured Fluid System Component Solutions   Fluid system components require high quality installations to meet the challenges of semiconductor manufacturing. Key components that impact the fab include:   Valves: High-performance valves, such as diaphragm, bellows, or needle valves, ideally regulate fluid flow in manufacturing facilities. Durable, high-quality valves provide the precision and control needed to improve the efficiency of production and handling processes for critical semiconductor manufacturing.   Fittings: High-purity fittings for tubing and hose systems and other critical components provide sealed connections to enhance the safety and purity of fluid system components.   Hoses: For precision manufacturing requirements, insulated hoses aid in thermal management so that process conditions within the production room can be optimally maintained. This is important because the slightest temperature fluctuation can damage chips and lead to production waste.   Flexible Tubing: Where conditions allow, flexible tubing can be used to reduce the number of fittings in a fluid system assembly. The tubing is bent to obtain the desired fluid path. Fewer fittings means less risk of leaks and damage due to vibration and movement.   Regulators: Regulators effectively control pressure at each stage of the semiconductor manufacturing process. Constant and accurate flow achieves consistent, high-quality yields while avoiding wasted fluid chemicals and specialty materials.   Filters: A single particle can affect semiconductor performance. The use of ultra-high purity filters eliminates particle contamination and minimizes chip damage.   Fluid system efficiencies in semiconductor manufacturing can be achieved with AFK-LOK's wide range of high quality valves, fittings, regulators, hoses and filters.

Using gases can be dangerous. Gas leaks or gas contamination are serious events that can lead to fire, explosion, personal injury or even death. All of these outcomes jeopardize the safety of on-site employees and risk damaging or destroying valuable equipment and property. Additionally, natural gas issues can leave an organization vulnerable to liability and regulatory fines. Accidents can occur due to operators disconnecting the wrong cylinders, or forgetting to disconnect cylinders and ignoring gas leaks. However, with the right equipment, these errors can be minimized to protect operators and maintain safety. Gas Safety Standards in Semiconductor Manufacturing Semiconductor manufacturing is one of the industries that must focus on gas handling safety. Semiconductor factories use a variety of gases in their production processes, making it imperative to ensure worker safety in day-to-day operations. Regardless of the stage of the semiconductor supply chain, vigilance is essential!   WOFLY recommends the following safety precautions when using gases in semiconductor manufacturing:   Identify exhaust hazards and conduct appropriate exposure assessments. - Identify and evaluate all potential exposure scenarios (e.g., startup, operation, maintenance, cleaning, emergencies). - Review the end pages of the WOFLY brochure, which contains permissible exposure limits for various substances.   -Provide proper ventilation to reduce airborne gas concentration levels.   -Provide personal protective equipment (PPE) as appropriate to prevent exposure to exhaust gases.   -Use respiratory protection where necessary to further minimize exposure and protect employees.   Choosing the right equipment for your facility is also critical to preventing hazardous gas exposure. The right tools will not only prevent hazardous incidents, but also improve operations and efficiency.

The origin of gas pressure regulators can be traced back to the mid-19th century with the development of devices to control and regulate gas flow and pressure in various applications. The early gas pressure regulators were primarily used in gas lighting systems, which were prevalent during that time.   One of the notable pioneers in the development of gas pressure regulators was Robert Bunsen, a German chemist and inventor. In the 1850s, Bunsen invented the Bunsen burner, a widely used gas burner in laboratories. The Bunsen burner incorporated a rudimentary pressure regulator mechanism to control the gas flow and maintain a stable flame. Over time, as gas utilization expanded into various industries and applications, the need for more advanced and precise gas pressure regulation arose. This led to the development of more sophisticated gas pressure regulators with improved control mechanisms.   The modern gas pressure regulators we see today have evolved through advancements in engineering, materials, and manufacturing techniques. They incorporate features such as diaphragm or piston-based control mechanisms, pressure sensors, and safety features to meet the diverse requirements of different industries and applications.   Today, gas pressure regulators are produced by several manufacturers worldwide, specializing in various types and sizes to cater to specific needs. These regulators undergo rigorous testing and certification processes to ensure their performance, reliability, and compliance with safety standards.   Overall, the origin and development of gas pressure regulators can be attributed to the increasing demand for controlled gas flow and pressure in various industries, evolving from basic mechanisms to sophisticated devices we rely on today.
