Расходомер жидкости

1.summary flowmeter is a kind of the vibration meters. It simple configuration, and install conveniently. It can measure and control various liquid (e.g.: water, oil, petroleum, alcohol, acid, alkali and different chemical fluids) gas (e.g.: air, oxygen, N2, natural gas, coal gas), and steam (e.g.: saturation steam,overheated water vapor). Intelligent: put smart chip will be placed at the field instrument, for the development of various functions Battery supply: no need cable, easy installation Low loss of power: battery can be used more than one year Field show: totalizer, instantaneousness, flow percentage Display: volume flow rate, standard volume flow rate, mass and sum, ten digits in engineering units of totalizer High accuracy: better than ±0.5% Linear function: set five points linear function Alarms: flow rate get more than initialization, show HIGH! High reliability: automatic check and adjustment General feature: outstanding range ability no moving parts, low pressure loss, long checking 2.specification Intelligentvortexflowmeter Three-wiresystemvortexflowmeter Two-wiresystemvortexflowmeter Powersupply 1.9606battery(passive) 2.12VDC,24VDC(Three-wiresystem) 3.24VDC(Two-wiresystem) 12VDC 24VDC 24VDC Output 1.Fieldshow,nopassiveandnooutput 2.Fieldshow,frequencyoutput 3.Fieldshow,output4 20mA,loadresistance≤500Ω frequencyoutput(highlevel:>4V,frequency:<3000Hz) lowlevel:0-1V duty-cycle:about50%; loadresistance≤750Ω Output4 20mADC Loadresistance≤750Ω Medium Liquid,gas,steam DNrange DN25-3000mm Accuracy ±0.5%,±1% Mediumtemperature -40 300°C Ambienttemperature Temperature:-40 +55°C,humidity:5%--90%,atmosphericpressure:86 106KPa Ex-proof ExiaIICT3-T6;ExdIIBT2-T5 Material 1Cr18Ni9Ti;316L Nominalpressure less than 2.5MPa Protectclass IP65,IP68 Fluidlowestpressure Pmin=2.6 delta P+1.25PoPo-gasificationpressure(Pa) Cable Cableterminal:Φ8mm,screwthreadInterface:M20×1.5 Cablespecifications:RVVP3×28/0.15,cablelength≤500m Feature Intelligent:putsmartchipwillbeplacedatthefieldinstrument,forthedevelopmentofvariousfunctions Batterysupply:noneedcable,easyinstallation Lowlossofpower:batterycanbeusedmorethanoneyear Fieldshow:totalizer,instantaneousness,flowpercentage Display:volumeflowrate,standardvolumeflowrate,massandsum,tendigitsinengineeringunitsoftotalizer Highaccuracy:betterthan±0.5% Linearfunction:setfivepointslinearfunction Alarms:flowrategetmorethaninitialization,showHIGH!
