Product Description

Gas Flow Totalizer DN150 Thermal Gas Mass Flow Meter for Hydrogen

 

   The Siko Instruments HG-TMFM Thermal Gas Mass Flow Meter Are Thermal Dispersion Type, It Utilizing The Constant Temperature Difference Methods Of Measuring Ga Mass Flow Rate. It Contains Two Reference Grade Platinum Rtd Sensors Clad In Protective Ss 316 Sheath. Its' Features Include Direct Mass Flow Measurement For Gases, Wide Range-Ability, Low Pressure Drop, Excellent Low End Sensitivity, And No Moving Parts.

   According To The Law Of Thermal Effect, There Is A Definite Mathematical Relationship Between Heating Power P, Temperature Difference T (TRH-TRMG) And Mass Flow Q In Thermal Gas Mass Flowmeter. P/Delta T = K1 + K2 F (Q) K3 K1, K2, K3 Areconstants Related To The Physical Properties Of Gases.

   Unique Temperature Difference Measurement Method Of Thermal Gas Mass Flow Meter Overcomes The Great Zero Drift Caused By Water, Oil And Impurities In The Gas When Measuring The Gas Flow With The Thermal Gas Mass Flow Meter Based On The Principle Of Constant Temperature Difference, Which Leads To The Disadvantage That Can Not Be Measured.
