Field display vortex flow meter

 

Vortex flow meter is based on Carmen (Karman) vortex principle,it can measure the gas,steam or volume flow rate of the liquid, volume flow  of  standard conditions or mass flow .Also it  can be applied as a flow transmitter for automation and control systems.

 

Scope:

Gas: air, compressed air, oxygen, carbon dioxide, nitrogen gas, natural gas, methane gas, ammonia 

gas etc.

Steam: superheated steam, saturated steam.

Liquid: water, oil
