一、原理 Work pricipal
冷热计量表能量计冷热量计能量表应用超声波技术**测量，2个测距传感器立即安装于空气流量计安全通道的两边，将匹配温度感应器各自安装于热交换器回路的渗水和循环水的管道中，将空气流量计安装于通道和出入口管上，空气流量计传出总流量数据信号，匹配温度感应器得出渗水和回水温数据信号，计算方式收集总流量数据信号和环境温度数据信号，通过测算显现出载热液态从人口数量至出入口所释放出来热量值。
超音波数据信号根据这俩感应器互相发送，一个信号顺水方位，一个信号倒流方位；
流量**测量是准时差法所进行的，时间差与流动速度大小正相关，能用公式计算表明：
构成：由积分兑换仪、超声波热量表和匹配传感器组成。
To test byultrasonic principle,two ultrasonic censor directly fix the twohead of the flow censor .The ultrasonic meter to test theflow,temperature test the difference from in to exit water. Thecalculator take the flow and tempeat-ure signal. And work out theheat The two ultrasonic sensors transmit to each tachother .
The way totest the flow is a diffrence way, time and flow speed isdirect ratio.Can be denote by this formula:
Compose:integraph,ultrasonic flow meter, and a part of cencer.
