Abstract

The invention discloses a multi-layer open channel portable flow measuring device and method based on the water impulse principle. A pressure sensor at the bottom of a U-shaped hollow pipe is used for measuring the instantaneous water head height, namely the water level H, of an overflowing section; meanwhile, layered multi-point flow velocity measurement components arranged at equal intervals comprise a series of position flow velocity meters composed of a tension sensor, a hollow perforated light steel ball and a light elastic steel rope to measure the flow velocity V1-n of different point locations, n depends on layers arranged according to the depth of the channel, and the instantaneous flow value of the whole overflowing section is further obtained through multi-layer flow accumulation. The device is simple in structure, intelligent in control, easy to operate, convenient to carry and capable of further improving the flow measurement precision.

Description

technical field [0001] The invention belongs to the technical field of open channel flow measurement devices, and relates to a multi-layered open channel portable flow measurement device based on the principle of water impulse. Background technique [0002] Water is the material basis for the existence of the earth's organisms. Water resources are the primary condition for maintaining the sustainable development of the earth's ecological environment. It is imminent to improve the utilization rate of water resources and reduce the waste of water resources. It is very important to save water in irrigation areas. Effective measures to save water, improve irrigation quality and irrigation efficiency, accurate flow measurement to ensure the effective use of water resources is the key, but the current channel flow measurement device has more or less some technical difficulties, the accuracy is not high, the applicability Not strong wait. At present, the main flow measurement meth...
