Problems solved by technology

This method has a better effect in a large range (such as a reservoir: tens of meters), and a larger error in a small range
4. Although the open channel water level and flow measuring instrument overcomes the shortcomings of the above three measuring instruments in principle, it is not convenient for field work to dismantle the protective case during data co

Description

technical field [0001] The invention belongs to a water level and flow measuring instrument, in particular to a wirelessly operable open channel water level and flow measuring instrument. Background technique [0002] At present, there are mainly four types of open channel water level flow measuring instruments: 1. Based on the principle of ultrasonic waves, the water level is measured first, and then the flow rate is converted. This method is greatly affected by environmental factors such as temperature, air pressure and air quality, and its accuracy is poor. 2. It is composed of a flow-driven impeller and connected to a counter, and uses the close cooperation between the flow rate and the product specification to measure the water level. This method is not convenient for mutual conversion between measuring ranges, and the floating objects in the channel will also seriously affect the measurement results. 3. The pressure difference generated by the water level on the bott...
