Doppler ultrasonic flowmeter brings you professional service,the remote underground liquid level monitoring solution has the characteristics of convenient data collection, processing, and orderly joint drainage and debugging management to improve urban management efficiency, which is a crucial link in the digitalization of rainwater and sewage management.

Doppler ultrasonic flowmeter brings you professional service,this product determines the current water level by detecting changes in the propagation time of ultrasonic waves in the air. There is no water quality impact issue, and it is suitable for measuring non high water levels. The product may be affected by ultrasonic measurement blind spots. At the same time, the water level and environmental temperature signals are uploaded to the cloud through NB-IOT or 4G. In areas with poor signal quality, a road specific antenna can be configured.
