Pressure Sensors, Flow Rate Sensors

Pressure sensors and flow sensors are devices that detect the pressure or flow rate of media such as fluids and gases. Pressure sensors usually detect the pressure of a liquid, oil, air, gas or another fluid, and have a mechanism that converts the detected pressure into an electrical quantity. They are sometimes called pressure converters. In contrast, flow sensors use a variety of different measurement methods, so models should be selected to match the fluid type. For example, there are impeller types that calculate the flow rate from the rotational speed of a rotor, volume/weight types suitable for measuring viscous liquids, elliptical gear types suitable for measuring oils and electromagnetic types that can measure minute fluid quantities. For both pressure sensors and flow sensors, the right model should be installed after checking the rated pressure / flow rate range, applicable fluid type, dielectric strength, environmental resistance and other detailed specifications and performance figures.
