ＴＯＦ是热传播时间 (ｔｈｅｒｍａｌｔｉｍｅｏｆｆｌｉｇｈｔ)的英文缩写。ＴＯＦ流量计的原理是在管道中装有 2根平行、相距一定距离的钨丝 ,上游一根是加热丝 ,下游一根是测温丝 ,加热丝中通以短脉冲电流使之发热 ,热量通过气体流动和热传导传给测温丝使测温丝温度升高。从
TOF is the acronym for thermal timeofflight. TOF meter principle is installed in the pipeline with two parallel, a certain distance away from the tungsten wire, the upstream one is heating wire, downstream one is the temperature measurement wire, the heating wire through the short pulse current to heat, the heat Pass the gas flow and heat conduction to the temperature measurement wire to make the temperature measurement wire temperature increase.
