Development of the Gas Flowmeter Based on Assembled Hot-Film

Abstract:

A gas flowmeter with temperature compensation is designed based on the single assembled hot-film probe. Experiments are carried out to analyze the temperature characteristics of the hot-film probe. The performance of the automatic temperature compensation units is studied. The flowmeter is tested on the Sonic Nozzle standard flowrate system for the calibration of flowmeters. The experimental results show that the precision is up to 0.6% and the ratio of the measurement range can be 60:1.
