Product Insights: Pressure Snubber

What is a Pressure Snubber? A pressure snubber is a device used to protect pressure gauges, sensors, and transmitters. As an example, they protect from sudden pressure spikes, pulsations, or surges that could damage the equipment or make pressure readings unreliable. How do Pressure Snubbers work? They work by evening out pressure fluctuations. It typically […]

Product Insights: Immersion Heaters

What are Immersion Heaters? Immersion heaters are devices designed to heat liquids or gases within a tank, vessel, or pipe. They operate by being submerged directly into the material that they are meant to heat. To explain further, immersion heaters achieve this by inducing an electric current into the heating element. Thus, the heating element […]

Product Insights: Isolation Pads

What are Isolation Pads? Isolation pads are materials or devices used to dampen or isolate vibrations and shock from machinery, instrumentation, or sensitive equipment. Their primary purpose is to protect both the equipment and the surrounding structures from vibrations, noise, and mechanical shock that might impact performance, safety, or longevity. Most pads are used in […]

What Is: Water Hammer?

What is Water Hammer and What Causes It? Water hammer is a phenomenon that occurs in plumbing and piping systems when the flow of water is suddenly stopped or changed, causing a shockwave to travel through the pipes. The sudden change in pressure results from the abrupt stopping of water moving at high speed, creating […]

Problem Solving: Valve Sizing

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: Pulsating Flow

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 […]

Product Insights: Pressure Transmitters

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

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 […]

Problem Solving: How Do I Prevent Cavitation?

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 […]
