Product Details

1、 Product Overview of Temperature Compensated Vortex Flow Meter
Specially designed for measuring saturated steam, it can automatically compensate for the density of saturated steam. Integrate flow and temperature compensation sensors into one. The sensing head is a field detachable body that can be replaced without affecting the fluid flow inside the pipeline.
2、 Main characteristics of temperature compensated vortex flowmeter
Through integrationTemperature pressure compensation vortex flowmeterIt can display the instantaneous mass flow rate, cumulative flow rate, temperature, pressure, etc. of saturated steam. The steam temperature can also be manually set, and the temperature and vortex sensor head can be replaced without stopping the fluid inside the tube.
