| description | The invention relates to the technical field of sewage treatment, in particular to a checkgate water flow measuring method. According to the method, the liquid level and the flow velocity in front of the checkgate, the opening height of the checkgate and the flow velocity after water flows through the checkgate are measured, the situation that the flow velocity at the water passing position of the checkgate is directly measured during traditional measurement, and the flow velocity fluctuates greatly and is inaccurate due to liquid level collapse is avoided by measuring the accurate data, and the flow velocity of the checkgate is accurately measured by calculating the accurate data. And a more accurate measurement result can be obtained. The method overcomes the limitation that a linear water inlet channel must be used in traditional flow measurement, can be suitable for application scenes that a water flow inlet channel has no straight pipe section and the water flow change is large, is wide in application ra |
