ABSTRACT: In order to improve the sensitivity of the thermal conductivity methane sensor, this paper pro-
poses a method for measuring the methane gas of low density by combining constant temperature detection
and digital compensates. Verification was carried out by thermodynamic analysis and the experimental results. ...
