The series of 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, convenient to connect with computer etc. The detector probe of sensor and the vortex generating body are installed separately, and the high temperature resistant piezoelectric crystal doesn't contact with medium, so the instrument is simple structure, good generality, and high stability. 

The Vortex Flowmeter sensor can be used to detect and measure the flow of all kinds of gas, fluid and steam.
