4~20mA Output Vortex Flow Meter for Measuring Compressed Air/Liquid/Steam

4~20mA Output Vortex Flow Meter For Measuring Compressed Air/Liquid/SteamThe vortex flow meter produces a velocity flow meter based on the Karman vortex principle for measurement and metering of conventional gases, vapors and liquids. The vortex flow sensor has high precision and a wide range ratio. It has no moving parts in use, which can improve mechanical stability and reduce maintenance. Vortex is almost unaffected by the temperature, pressure and composition of the medium when measuring the working volume, so it is convenient for the calibration production of the instrument. Therefore, the vortex flow sensor is widely used in production and life.Technical ParametersMain technical parameter listNominal diameter(mm)15,20,25,40,50,65,80,100,125,150,200,250,300,(300~1000 Plug-in)Nominal pressure(MPa)DN15-DN200 4.0(>4.0 Agreement supply),DN250-DN300 1.6(>1.6 Agreement supply)Medium temperature(ºC)Piezoelectric:-40~100,-40~250,-40~330;Capacitive: -40~400,-40~500(Agreement supply)Body material 1Cr18Ni9Ti,(available under other materials agreement)Allowable vibration accelerationPiezoelectric:0.2g      Capacitive:1.0~2.0gAccuracy±1%R,±1.5%R;Plug-in:±2.5%R,Range1:6~1:25Supply voltagesensor:DC 24V(DC);Battery powered:3.6V batteryoutput signalSquare wave pulse (excluding battery-powered type): high level ≥ supply voltage minus 1V, low level ≤ 1V; current: 4 ~ 20mAPressure loss coefficientMeet the JB/T9249 standard Cd ≤ 2.4Explosion-proof markEXiaIICT4 GaIntrinsic safety parametersUi= 28VDC, Ii=100mA, Pi=0.657W, Ci=0.μF, Li=0mHProtection levelOrdinary IP65 diving type IP68Environmental conditionsTemperature -20 ° C ~ 55 ° C, relative humidity 5% ~ 90%, atmospheric pressure 86 ~ 106kPaApplicable mediumGas, liquid, steamTransmission distanceThree-wire pulse output type: ≤300m, two-wire standard current output type (4~20mA) ≤1500m; load resistance ≤500Ω; RS485≤1200m.  Instrument caliber(mm)LiquidsGas Measuring range(m3/hr)Output frequency range(Hz)Measuring range(m3/hr)Output frequency range (Hz)150.3-524-4004-20352-1761200.6-1023-8326-30254-1273251.2-1621-3208-55161-1112321.8-2018-20010-12097-1172402-4010-19027-205134-1018503-608-15035-38087-952654-856-12060-64071-764806.5-1304.1-8286-110054-69610015-2204.7-69133-170042-54815030-4502.8-43347-400034-39220045-8002-31560-800023-32630095-2001.2-241360-1800016-216...............Product ShowcaseCompany InformationRelaterd products  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
