【Abstract】 In this paper a novel intelligent gas flowmeter of heat transfer is introudced. The key problem of heat transfer sensor is how to compensate for gas temperature. By theoretical research,a mathematical model is obtained and actual calibration and measurement test is carried out. It makes convenient to compensate accurately for variety of gas temperature. The sensor volume is so small that it hardly makes pressure loss during measurement.更多还原
