working principle:
LUG series vortex flowmeter is a new type of flowmeter for closed pipeline fluid flow measurement based on Karman vortex principle. Because of its good medium adaptability, it can directly measure the volume flow of steam, air, gas, water and liquid without temperature and pressure compensation. It is equipped with temperature and pressure sensor to measure the volume flow and mass flow of the standard condition. It is throttling. An ideal replacement for flow meters.
Features:
LUG series vortex flowmeter is characterized by small pressure loss, large measuring range and high precision. It is almost unaffected by parameters such as fluid density, pressure, temperature and viscosity when measuring volumetric flow. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time. The vortex flowmeter uses a piezoelectric stress sensor that operates over a temperature range of -20 ° C to +250 ° C. There are analog standard signals and digital pulse signal outputs, which are easy to use with digital systems such as computers.
