Products Description
Vortex flow meter is a volumetric flow meter that measures the volumetric flow rate, standard volumetric flow rate, or mass flow rate of gas, steam, or liquid based on the Karman vortex principle. Mainly used for flow measurement of industrial pipeline medium fluids, such as gases, liquids, vapors, and other media.
Its characteristics are small pressure loss, large range of measurement, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring the volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can be stable for a long time. The vortex flowmeter adopts a piezoelectric stress sensor with high reliability and can operate within the working temperature range of -20 ℃ to+250 ℃. There are analog standard signals and digital pulse signal outputs, which are easy to use in conjunction with digital systems such as computers. It is a relatively advanced and ideal measuring instrument.
