说明：  目前我国的集中供热、采暖系统计量收费逐渐展开，热力站中主要的计量装置就是热量表。热量表是一种以微处理器和高精度传感器为基础的机电一体化仪表，与建筑业过去已经普遍使用的计量表，比如水表、电表、煤气表相比，它有着更复杂的设计和更高的技术含量。热量表通过温度和流量两种传感器，分别测得热载体在进出口的温度和流量，再经过密度和热焓值的补偿及积分计算而得到热量值。
(At present, the central heating and heating system in our country is gradually charging and charging. The main metering device in the heat station is the calorimeter. Heat meter is a kind of electromechanical instrument with microprocessor and high precision sensor based, and the construction industry in the past has been widely used in the meter, such as water meter, gas meter, it has a more complex design and higher technology content. Heat meter through the temperature and flow of two sensors, respectively, the heat carrier temperature and flow at the entrance and exit, and then through the density and enthalpy value of compensation and integral calculation to get the heat value.)
