HQ 980 thermischen Gasmassendurchflussmesser

1.summary HQ980 Thermal Mass Flowmeter bases on the U.S. technology,patent (No. 98224228.X). we havenational explode-proof (GYB98463) and JJG879-95 certification. HQ980 Thermal Mass Flowmeter is one of the most advanced flowmeter in gas mass monitoring. The sensor of HQ980 Thermal Mass Flowmeter is related to flow rate of the gas mass and meet the situation which the temperature and pressure is unstable. 2.Specification lMedium Allkindsofgases(pure&stablegases),exceptforacetylene lDisplay:totalize10characteristic,instantaneous4characteristic lSignalOutput 4 20mA,resistance≤500Ω lAccuracy :±1.0% lRepeatability ±0.2%fullscalemeter lEnvironmenttemperature -40°C 50°C lEnvironmenthumidity:5-90% lThetemperatureofmedium:-40°C 120°C lEnvironmentPressure :≤2.5MPa lAntisepsis:1Cr18Ni9Ti;316L lStraightpipe:15D,3DwithRectifier lExplode-proof:dIICT3 lWater-proof:IP65,IP68 lPower:24VDC±10%,≥350mA lCable: 8mmM20x1.5 3.air flow rate 4.some max limit of gas
