Introduction
Vortex Flowmeter is based on Carmen Vortex Principle, which adopts piezoelectric crystal as testing
components. It is a new kind of stress detecting vortex flowmeter. It has the advantages of wide range rate,
high accuracy, low pressure loss, good medium generality, pulse signal output proportional to flow, conveni
ent to connect with computer etc.
Application:
Gas: air,oxygen,carbon dioxide,nitrogen,natural gas,lpg,biogas,etc
Liquid: water,oil,etc
Steam:saturated steam and superheated steam,vapor etc
