Product Description Gas flow measurement dn80 thermal mass flow meter for hydrogen Thermal Type Gas Mass Flowmeter utilizes the principle of heat exchange to measure fluid -flow. This meter employs method of constant temperature difference to accurately measure gas mass flow, and it has the advantages of small size, the high degree of digitization, easy installation, accurate measurement, etc. The sensor part consists of two platinum resistance converters of the reference level. It utilizes the bridge-type loop circuit, with one converter measuring fluid temperature and another maintaining constant temperature difference that is higher than fluid temperature. The measurement can be made under high temperature and high-pressure situation.Technical Parameters Of Thermal Gas Mass Flow Meter Measuring mediumAll kinds of gases (excluding acetylene)Range of caliberDN10~4000mmDN25~2000mmRange of velocity of flow0.5~100Nm/sOrder of accuracy±1%Working temperatureSensor: ambient temperature-10~+200Chigh-temperature modification-10~+350CConverter: -10~+45CWorking pressureMedium pressure<2.5 MpaMedium pressure<4.0 MpaPower supply sourceDC24V or AC220VOutput signal4~20mA(photoelectric isolation with top load of 500Ω) RS-485(photoelectric isolation), HART protocolPipeline materialcarbon steel, stainless steel, plastics, etc.DisplayAll-in-one type: four lines with LCDLevel of protection of one-time meterIP67Keywords air compressor flow meterConverter materialStainless steelStainless steel, carbon steelFeatures1) Measuring the mass flow or volume flow of gas.2) Do not need to do temperature and pressure compensation in principle with accurate measurement and easy operation.3) Wide range: 0.5Nm/s~100Nm/s for gas.4) Good vibration resistance and long service life.5) Easy installation and maintenance.6) Digital design, high accuracy, and stability.7) Configuring with RS485 or HART interface to realize factory automation and integration.Flow Range ItemThermal gas mass flow meterDiameter Flow range((Nm3/h))DN201.2~120 (Flange type)DN252.5~168.5 (Flange type)DN324~275 (Flange type)DN406~430 (Flange type)DN509~671.5 (Flange type)DN8020~1718.5 (Flange type)DN10030~2685 (Flange type)DN15060~6045 (Flange type)DN15060~6045 (plug-in)DN200120~12738.5 (plug-in)DN250150~18779 (plug-in)DN300200~28000 (plug-in)DN400350~48955.5 (plug-in)DN500600~77177.5 (plug-in)DN600800~100000 (plug-in) Terminal DiagramMarkDescriptionLAC85V~AC220V LNAC85V~AC220V N24V24V Power supply positive pole0V24V Power supply 0VP+Pulse output positive poleP-Pulse output negative poleI+Current output positive poleI-Current output negative pole485+/ARS485 communication interface A485-/BRS485 communication interface BALARM 1Alarm output 1ALARM 2Alarm output 2Why choose Huadian Automation thermal gas mass flow meter?1.
