超声波流量计是基于传播速度差法超声测量而研制的，通过传感器向流体发射超声信号，在其受到流体流动影响之后再接收此超声信号并将检测结果用于流量测量的计量器具。该仪表集测量、积算、显示于一体，采用微功耗技术，可实现最小流量（软件可调）的准确测量，同时仪表具有体积小、稳定性好、抗干扰能力强等特点。

仪表具有多种编程功能，可灵活控制水泵起停超声测流技术，可实现多角度安装，仪表测量不受影响，同时使管道压力损失降到最低。

The ultrasonic flowmeter is developed based on the ultrasonic measurement of the propagation velocity difference method. The ultrasonic signal is transmitted to the fluid through the sensor, and the ultrasonic signal is received after it is affected by the fluid flow and the detection result is used for the flow measurement measuring instrument. The instrument integrates measurement, integration, and display. It adopts micro-power consumption technology to achieve accurate measurement of minimum flow (software adjustable). At the same time, the instrument has the characteristics of small size, good stability, and strong anti-interference ability.The instrument has a variety of programming functions, which can flexibly control the start and stop of the water pump ultrasonic flow measurement technology, and can realize multiangle installation, the instrument measurement is not affected, and the pipeline pressure loss is minimized.
