Notes on turbine flowmeter

Flow meter /

The turbine flowmeter is a typical velocity flowmeter. It has the characteristics of high measurement accuracy, fast response and high pressure resistance, so it is increasingly used in industrial production. The turbine flowmeter works based on the principle of conservation of fluid momentum. The measured fluid pushes the turbine blades to rotate the turbine. Within

How to judge whether the differential pressure transmitter is working properly

Pressure Transmitter /

During the field use of differential pressure transmitters, how do we judge whether their working status is normal? Since most of the faults of differential pressure transmitters are zero drift and blockage of pressure pipes, the scale is rarely calibrated point by point on site, but the zero point and change trend of the differential
