Product Description

Voltage pulse 4 20mA HART RS485 Vortex Flowmeter

Overview
 

QFM403 inteligent Vortex flowmeter is a kind of velocity flowmeter,Based on Karman vortex theory, it usespiezoelectric crystal to detect the vortex frequency generated by the fluid passing through the triangularcolumn in the pipeline, so as to measure the flow rate of the fluid.it has features of not only excellent.
