What is a Valve? Before diving into valve sizing an understanding of what valves are is needed. A valve is a mechanical device that controls the flow of a liquid, gas, or slurry through a systematic passageway such as pipes. A valve achieves control by stopping, varying, or starting the fluid flow, controlling the direction […]
What is a Pressure Gauge? Pressure gauges are devices used to measure the pressure of a gas or liquid within a system. The pressure generated is usually measured in force per unit of surface area. For example, psig or Pounds per Square Inch Gauge is such a measurement. Most pressure gauges feature a dial or […]
What is Pulsating Flow? Pulsating flow refers to a type of fluid flow where the flow rate or pressure varies cyclically over time. This variation can occur due to changes in external factors, such as the operation of pumps, compressors, or other mechanical systems. The fluid is then forced to move in bursts or pulses […]
What is a Pressure Transmitter? Pressure transmitters are devices used to measure the pressure of liquids or gases in pipes or containers. The pressure readings are then converted into a standardized electrical signal that can be easily interpreted by a control system. Pressure transmitters are often called a pressure transducer but there are key differences […]
What Is Sensor Fouling? Sensor fouling is the accumulation of unwanted substances or materials on the surface of a sensor. These substances and materials can interfere with the sensors ability to detect and measure accurately. The mechanisms of fouling are complex and depend on many factors such as the sensor type, the operating environment, and […]
What is cavitation? Prevent cavitation by understanding what cavitation and what causes it. EXPRO Controls published a blog post regarding an in-depth analysis of ‘what is cavitation‘ on January 29th, 2025. However, I will give a brief explanation. Cavitation is the process in which the liquid’s static pressure falls below its vapor pressure, resulting in […]
What is a Leak Detection System? A leak detection system is a method used to identify and monitor leaks in various systems. Examples include pipelines, tanks, water systems, or gas lines. These systems are designed to detect the presence of leaks early. Thus, helping to prevent damage, loss of resources, and safety hazards. Throughout this […]
What is a Vortex Flow Meter? A vortex flow meter is a type of volumetric flow meter used to measure the flow rate of fluids or gases in a pipe. How does a Vortex Meter Work? Vortex meters utilize the natural phenomenon known as the vortex shedding principle. The principle requires a liquid or gas […]
What is Cavitation? Cavitation is the process in which the liquid’s static pressure falls below its vapor pressure, resulting in the creation of small vapor-filled cavities in the liquid. Two types of cavitation: Inertial and Non-Inertial. Inertial Cavitation It is a specific type that occurs when the fluid pressure fluctuates rapidly and drops significantly below […]
What is a Heat Trace System? Heat trace systems are a series of electrical cables that generate heat when electrical current passes through it. The heat generated by these systems is transferred to the surrounding pipes, equipment, or concrete to maintain a specific temperature. What Components Make-Up the System? Components that make up a heat […]
