Applied to the open channel flow meter scale used in irrigation and water conservancy

Abstract: the use of open channel flow meter scale used in irrigation and water conservancy information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Hangzhou brera Ann according to the environmental special research and development of irrigation and water conservancy irrigation and water conservancy is special open channel flow meter. Along with our country's latest five-year plan on the increase of irrigation and water conservancy facilities, and a lack of water resources is more and more, irrigation and water conservancy in extensive use of open channel flow. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the use of open channel flow meter scale used in irrigation and water conservancy article details. According to the environmental special research and development of irrigation and water conservancy irrigation and water conservancy is special open channel flow meter. Along with our country's latest five-year plan on the increase of irrigation and water conservancy facilities, and the increasingly scarce water resources, irrigation and water conservancy will use a lot of open channel flow meter to measure water flow. But the use of open channel flow meter in irrigation and water conservancy facilities, with the use of different sewage treatment industry, irrigation and water conservancy environment more complex, the scene is often the channel, and the gate open. We according to the scene of the irrigation and water conservancy condition, production out of the water conservancy special open channel flow meter. Use on irrigation and water conservancy, want to consider a few features: 1. The power supply. Many site can not power supply, or only 380 v three-phase electricity. 2. Water channels: many wrong mark, super wide, large channel. There is a lot of water channels. Channels and gate, resulting in the change of water flow. 3. Installation: a lot of field should be according to actual condition to select installation. Open channel flowmeter measurement principle: direct measurement of physical quantities is level. When used in open channel flow measurement, installation of measuring weir trough in open channel. Measuring weir tank in the open channel flow into the size of the liquid level of high and low. Meter measuring weir tank water level, and then according to the corresponding measuring weir tank water level & ndash; Back the relationship between traffic flow. Flow measuring principle of measuring weir trough: the circulation flow in open channel flow, the greater the level is higher; The smaller the flow rate, the lower level. By measuring the water level can be calculated by the traffic. Common in the open channel flow and water level, the corresponding relationship between the channel slope ratio and surface roughness. Measuring weir trough installed within the channel, the throttling effect, make the open channel flow and liquid level in a fixed corresponding relation, the corresponding relations between mainly depends on the structure of the measuring weir tank size, the influence of channel reduced to small zui. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
