Applications

In the field of industrial measurement, differential pressure is a key tool for the accurate and reliable monitoring of the levels of liquids and liquefied gases within pressurised tanks. Pressurised tanks are used for a number of reasons, including ensuring a constant output, eliminating foam, providing a barrier for caustic materials and liquefying gas for easier storage. In all of these scenarios, a differential pressure transmitter will only measure the difference between the static pressure and the overall pressure. The standard formula for hydrostatic pressure consists of three variables: pressure, density, and height. The sensor measures pressure, with density input by the customer as a constant, and the height is the product level. For this formula to be effective, it is crucial that density remains relatively constant. With a known density and pressure value, the pressure sensor's electronics can accurately and reliably calculate liquid level from the differential pressure.
