GVF300 digital steam vortex flow meter is a flow meter operating with Karman Vortex Street principle for flow rate of steams (saturated steam, superheated steam, etc.). It could be used in automatic control system as flow transmitter. The product adopted advanced differential technique, together with measurement of isolating, shielding and filtering, it had possesses better anti-vibration performance and signal stability.

Note for type selection
GVF100 digital gas vortex flow meter is mainly applicable for measurement of air, oxygen, nitrogen, coal gas, natural gas, chemical gas, etc.
Type selection process
Select main model and structure first, then ensure other specifications according to requirement, i.e. main model + nominal diameter + structure + accuracy + nominal pressure + Max. temperature of the medium + more function + power + output + installation + explosion proof.
