I. product principle

LU vortex flowmeter is mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, vapor and other media. It is characterized by small pressure loss, large range and high precision, and is almost unaffected by parameters such as fluid density, pressure, temperature and viscosity when measuring the volume flow in working conditions. No moving mechanical parts, so high reliability, small maintenance. Instrument parameters can be stable for a long time. The vortex flowmeter adopts piezoelectric stress sensor with high reliability and can work in the operating temperature range of -20℃ ~ +250℃. It has the analog standard signal, also has the digital pulse signal output, easy to use with the computer and other digital systems, is a more advanced, ideal flow meter.
