Air FLOW METER
VORTEX TYPE AIR FLOW METER
Standard type vortex flow meter is used in numerous branches of industry to measure the volume flow of liquids, gases and steam. Applications in the chemicals and petrochemicals industries, for example, in power generation and heat-supply systems involve widely differing fluids: saturated steam, superheated steam, compressed air, nitrogen, liquefied gases, flue gases, carbon dioxide, fully demineralized water, solvents, Conduction Oil, boiler feedwater, condensate, etc.

Flange Vortex Flow Meter Installation Requirements:
The installation of vortex meter has higher requirements, to guarantee the better accuracy and working properly. Vortex flow meter installation should keep away from the electric motors, big frequency converter, power cable, transformers, etc.
Do not install in the position where there has bends, valves, fittings, pumps etc, which could cause flow disturbances and influence the measurement.
The front straight pipe line and after straight pipe line should follow below suggestion.
