86-21-69585001
Large range of application,used to measure steam,gas and liquid
No zero point deviation
Small permanent pressure loss
Precise machining equioments are employed in manufacturing of FFM63 series of vortex flowmeter.Optimized and integrated probe and piezoelectric crystal are processed by special techniques,providing only a little natural self-vibration frequencies of the flowmeters in cooperartion with amplifying circuits.
Technical features:
Measureed fluids:saturated vapor,wuper-heated steam,gases,liquids(avoid multiphase flows)
Nominal diameter:DN4-DN10
Measurement correctness:Gas:1.5%;Liquid:1.0%
Repeatability:Gas:0.5%;Liquid:0.33%
Wide measuring ranges,the range ration can be 10:1
Within a certain range of Reynolds number,the specialty of a flow rate will not be influenced by the pressure,temperature,viscosity and contents of the fluid,it only relates to the shape and dimension of the vortex generator
