摘要
超声波水位测量系统由传感器和变送器构成。传感器向物体表面发射超声波，接受反射波，并作为定向传送器将电信号传送到变送器，由变送器完成智能化回波分析，完成非接触连续地水位测量。测量范围：液体３０ｍ。工作温度：－２０～８０℃。水位测量精度：１ｍｍ。
The water level measure system by Prosonic consists mainly of sensors and a transmitter. The sensor sends out an ultrasonic wave towards surface of object and takes over the backward wave. Then it directionally sends the backward wave into the transmitter as an electrical signal. Finally, the transmitter executes a intelligent analysis. It is a non-contact and continual means for gauge observation. Measuring range and accuracy: 30m and 1mm for fluid. Working temperature: -20℃￣80℃.
