摘要
简要介绍使用差压式流量传感器进行一般气体流量测量时的温压补偿方法;指出了差压方式流量传感器测量一般气体的通用流量温压补偿公式,并写出了公式的推导过程;与线性流量传感器温压补偿方法进行对比,强调指出了采用差压式流量传感器时进行温压补偿的注意要点。对公用工程中的一般气体的流量计量工作有一定的指导作用。
It introduces briefly the method of the general gas flow measurement with the temperature and pressure compensation by the flow meter of pressure difference. It shows the formula. Simultaneously, it shows the derivation of the formula. Additionally, it contrasts this formula with another formula of the general gas flow measurement with the temperature and pressure compensation by the linear flow meter. It specially shows the essential of the general gas flow measurement with the temperature and pressure compensation by the flow meter of pressure difference. It＇s important for the general gas flow measurement in the public engineering of industry.
