Ultrasonic water measuring device for open channel

Technical Field

The utility model relates to an open channel ultrasonic water measuring device, and belongs to the technical field of open channel water measuring.

Background

Two modes, namely a weir trough water level method and a flow velocity area method, are generally adopted in the current stage of open channel water surveying.
