Description

/ / / X Изобретение относитс  к гидротехнике и мелиорации, в частности к способам измерени  расхода воды. Цель изобретени  - повышение точности измерени  расхода воды. На чертеже схематически изображено гидротехническое сооружение, выполненное по типу водослива с широким порогом. Способ измерени  расхода воды осуш ,ествл етс  следующим образом. Две водомерные рейки устанавливают в верхнем бьефе 1, располага  на рассто нии (4-5) Но от входа на водослив, и в нижнем бьефе 2 в створе схода воды с порога водослива 3. По рейкам фиксируютс  уровни воды, а затем определ ютс  глубины соответственно Но и hex. Величину расхода воды определ ют по формуле/// X The invention relates to hydraulic engineering and amelioration, in particular to methods for measuring water flow. The purpose of the invention is to improve the accuracy of measurement of water flow. The drawing shows schematically a hydraulic structure made according to the type of weir with a wide threshold. The method for measuring the flow of water is dried as follows. Two water gauges are installed in the upstream 1, located at a distance of (4-5) But from the entrance to the weir, and in the downstream 2 in the alignment of water from the weir threshold 3. The racks fix the water levels and then determine the depths respectively But also hex. The amount of water flow is determined by the formula

ускорение силы т жести. Предлагае.мый способ позвол ет достичь увеличени  точности измерени  подаваемых на систему орошени  расходов воды, что исключает подачу излишних объемов воды. Формула изобретени  Способ измерени  расхода воды, включающий замеры глубины воды в верхнем и нижнем бьефах и определение величины расхода, отличающийс  тем, что, с целью повышени  точности измерени , замер глубины в нижнем бьефе осуществл ют на сходе с водосливного порога в фиксированном сечении, определ емом положением выходной грани водосливного порога, а величину расхода определ ют по формулеacceleration of the force of gravity. The proposed method allows you to achieve an increase in the accuracy of the measurement of the flow of water supplied to the irrigation system, which eliminates the supply of excessive amounts of water. DETAILED DESCRIPTION OF THE INVENTION A method for measuring water flow, including measuring the depth of water in the upper and lower pools and determining the flow rate, characterized in that, in order to improve the accuracy of the measurement, the depth in the lower pool is measured at the outlet from the overflow threshold in a fixed section defined the position of the exit face of the weir threshold, and the flow rate is determined by the formula
