1、 Equipment composition

2、 Equipment principle

The product has three functions: measuring average flow velocity, measuring water depth, measuring water temperature, and can display cross-sectional flow rate.

Among them, temperature sensors are used for water temperature measurement, ultrasonic water level gauges are used for water depth measurement, and flow velocity measurement is achieved through installation

Yu QuRoad sideOn the wallMeasured by four sets of ultrasonic probes.By measuring the average flow velocity, water level, and cross-sectional size, the cross-sectional area can be determined

Traffic.

3、 Application scope

Mainly suitable for widths less thanA 1-meter rectangular regular channel.
