Recently, Shandong Water Resources purchased even electromagnetic flowmeters for use in farmland irrigation projects at our factory. Actually, electromagnetic flowmeters are widely used in municipal water supply, steel, petroleum, chemical, power, industrial, water conservancy, and water resources and other departments. The measurement of the volumetric flow of liquids is particularly suitable for the flow measurement of channels, small rivers, and the measurement of sewage in environmental protection processes. Sewage flow meter installation requirements for farmland irrigation First, the choice of electromagnetic sewage flow meter installation environment: as far as possible away from equipment with strong electromagnetic fields, such as large motors, large transformers, large-scale inverters. The installation site should not have strong vibrations, the pipelines should be firmly fixed, and the ambient temperature should not change much (to prevent the change of solid-liquid two phases ) . The installation environment should be easy to install and maintain. Second, the choice of electromagnetic sewage flowmeter installation location: The installation position must ensure that the pipeline is always full of measured liquid. Select a place where the liquid flow pulse is small, ie, keep away from local resistances such as pumps, valves, and elbows. When measuring two-phase ( solid, liquid, and gas, liquid ) liquids, choose a place that is not likely to cause phase separation. The inner diameter or perimeter of the pipe being measured is easy to measure, and the ellipticity should be small. Third, the length of the straight section of the electromagnetic sewage flowmeter: The length of the straight section on the upstream side of the sensor installation pipeline should be greater than or equal to 10D , and the downstream side should be not less than 5D (D is the diameter of the measured pipeline ) . Fourth, flow control valve and regulating valve: The flow control valve should be installed in the measured pipeline on the upstream side of the sensor, and the flow regulating valve should be installed on the downstream side of the sensor. Flow, usually the flow control valve should be fully open.
