一、工作原理 Work pricipal

      空調冷熱量計量表運用超聲波原理測量，兩個超聲波傳感器直接安裝在流量傳感器通道的兩端，將配對溫度傳感器分別安裝在熱交換回路的進水和回水的管道上，將流量傳感器安裝在入口和出口管上，流量傳感器發(fā)出流量信號，配對溫度傳感器給出進水和回水的溫度信號，計算器采集流量信號和溫度信號，經過計算顯示出載熱液體從人口至出口所釋放的熱量值。

      超聲波信號通過這兩個傳感器相互發(fā)射，一個信號順流方向，一個信號逆流方向；

      流量的測量是按時差法進行的，時差與流速的大小成正比，可用公式表示：

      組成：由積分儀、超聲波流量計和配對傳感器組成。

      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 .
