GFM83 Intelligent Vortex Durchflussmesser

GFM83 Intelligent Vortex Flow meter Precise machining equioments are employed in manufacturing of GFM83 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:GFM83 Intelligent Vortex Flow meter Measureed fluids:saturated vapor,wuper-heated steam,gases,liquids(avoid multiphase flows) Nominal diameter:DN25-DN300 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(20:1) 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. Measurement of volume flow do not need temperature and pressure compensation. Technical specifications:Measuring fluidSaturated vapor,super-heated steam, compressed air and other general gas and liquidMeasurement rangeGas:7m/s-40m/s,liquid:0.7m/s-7m/sRepeatabilityLiquid:0.33%,gas:05%PrecisionLiquid:0.5,gas:1.0Rated pressure1.6Mpa,2.5Mpa,6.3MpaProtection gradeIP65Material of meter body304 stainless steelPower supply24VDC(or 12 VDC), 3.6V by lithium-ion batteryOutput signalpulse output,4-20mA current output,RS485 communicationFluid temperature-40°C-250°C(average type),100°C-350°C(high temperature type)Electric interfaceM20*1.5Explosion styleNon-anti-explosive,anti-explosiveEnvironmental temperature-35°C-60°C(no LCD),-5°C-60°C(with LCD)Relative humidity5%-95°C
