Development and calibration of thermal gas mass flowmenter for pipe gas

LI Cheng wei, LI Chao hui, DAI Jing min, CHEN Shou ren ( School of Electrical Engineering & Automation, Harbin Institute of Technology,Harbin 150001, China)  
In order to solve the gas flowmeter's lower limit problems,such as low accuracy at lower limit or the small gas flow leakage,a novel gas flowmenter based on the compelled forced convection principle and the principle of hot-wire anemometer has been successfully developed,in which,micro hot-wires are used as sensitive elements,a resistive heater is used for measurement of gas flow rate,and a support bridge technology is adopted in the measuring circuit.The sensitivity of the meter has been improved and the dead space in it has been reduced.Pipe gas is an especial substance,its measurement precision is affected by many factors,the flowmeter must be calibrated before use.Based on lots of the actual process gas flow calibration experiments,and the analyses of the affection of thermal convection modulus,a new compensating method is proposed.Throungh these experiments,the instrument's lower limit nearly reach zero,successfully solve the problem of low flow rates leakage.
