一、工作原理 l

      中央空调水冷量表，空调水冷量表运用超声波原理测量，两个超声波传感器直接安装在流量传感器通道的两端，将配对温度传感器分别安装在热交换回路的进水和回水的管道上，将流量传感器安装在入口和出口管上，流量传感器发出流量信号，配对温度传感器给出进水和回水的温度信号，计算器采集流量信号和温度信号，经过计算显示出载热液体从人口至出口所释放的热量值。

      超声波信号通过这两个传感器相互发射，一个信号顺流方向，一个信号逆流方向；

      流量的测量是按时差法进行的，时差与流速的大小成正比，可用公式表示：

      组成：由积分仪、超声波流量计和配对传感器组成。

      To test by ultrasonic principle,two ultrasonic censor directly fix the two head of the flow censor .The ultrasonic meter to test the flow,temperature test the difference from in to exit water. The calculator take the flow and tempeat-ure signal. And work out the heat quantity. The two ultrasonic sensors transmit to each tach other .

      The way to test the flow quantity is a diffrence way, time and flow speed is direct ratio.Can be denote by this formula:

      Compose:integraph,ultrasonic flow meter, and a part of cencer .
