| description | The invention discloses an open channel flowmeter for rectangular channel flow monitoring and a flow measuring method thereof. The open channel flowmeter is composed of a channel water flow form monitoring device and a flow monitoring controller which are arranged in a rectangular channel. The flow measuring method comprises the following steps: S1, constructing a rectangular channel three-sectionflow measurement environment; S2, enabling the control module to send a control instruction to control the upstream side pressure water level monitor and the downstream side pressure water level monitor to synchronously collect water level data of an upstream side monitoring section Ls and water level data of a downstream side monitoring section Lx according to a set collection frequency within aset monitoring time period delta t; and S3, calculating the excess flow of the monitored section Le. According to the invention, the traditional flow measurement method is broken through, and the average flow of the monitored |
