Installation environment and schematic diagram of sewage flow meter

Abstract: The installation environment and schematic information of sewage flow meter are provided by excellent flow meter and flow meter manufacturers. The sewage flowmeter can be widely used in the measurement of the volume flow of conductive liquids in municipal water supply, steel, petroleum, chemical industry, electric power, industry, water conservancy, water administration and water resources, etc. It is especially suitable for the flow measurement of channels, small rivers and environmental protection. processor. More flowmeter manufacturers select models and price quotations. You are welcome to inquire. The following is the installation environment and schematic diagram of the sewage flowmeter. The sewage flowmeter can be widely used in the measurement of the volume flow of conductive liquids in municipal water supply, steel, petroleum, chemical industry, electric power, industry, water conservancy, water administration and water resources, etc. It is especially suitable for the flow measurement of channels, small rivers and environmental protection. Wastewater metering for treatment. In this article, let's talk about its installation environment and provide installation diagrams for users' reference. Installation requirements for sewage electromagnetic flowmeter: 1) Selection of installation environment for sewage electromagnetic flowmeter: It should be kept away from equipment with strong electromagnetic fields, such as large motors, large transformers, large frequency converters, etc. There should be no strong vibration in the installation site, the pipeline is firmly fixed, and the ambient temperature changes little (to prevent the change of solid-liquid two-phase). The installation environment should be easy to install and maintain. 2) Selection of the installation location of the sewage flowmeter: The installation location must ensure that the pipeline is always filled with the liquid to be measured. Choose a place with small liquid flow pulses, that is, keep away from local resistance parts such as pumps, valves and elbows. When measuring two-phase (solid, liquid and gas, liquid) liquids, a place that is not easy to cause phase separation should be selected. The inner diameter or circumference of the pipe under test is easy to measure, and the ovality should be small. 3) Length of straight pipe section: The length of the straight pipe section on the upstream side of the sensor installation pipeline should be greater than or equal to 10D, and the downstream side should not be less than 5D (D is the diameter of the pipe under test). 4) 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. When the flow rate, usually the flow control valve should be in the fully open state. Sewage flowmeter installation example diagram and requirements: 1. It should be installed at the lower part of the horizontal pipeline and vertically upward, and avoid installing it at the highest point and the vertical downward part of the pipeline; 2. It should be installed at the rising part of the pipeline; 3. At the opening The discharge pipeline should be installed at the lower part of the pipeline; 4. If the pipeline drop exceeds 5m, install the exhaust valve downstream of the sensor; 5. The control valve and cut-off valve should be installed downstream of the sensor, not installed in Upstream of the sensor; 6. The sensor cannot be installed at the inlet and outlet of the pump, but should be installed at the outlet of the pump; 7.

How to correctly select the installation node for the discharge valve: Correct selection of the installation point and correct installation of the flow meter are both very important links. Either will affect the measurement accuracy, and the worst will affect the service life of the flowmeter, or even damage the flowmeter. Special attention should be paid when choosing the installation location: the axis of the non-measuring electrode must be approximately horizontal; the measuring pipe must be completely filled with liquid; there must be at least 5×D (D is the inner diameter of the flowmeter) length of straight pipe, at least 3×A straight pipe section with a length of D (D is the inner diameter of the flowmeter); the flow direction of the fluid is the same as the direction of the arrow of the flowmeter; if there is a vacuum in the pipeline, it will damage the lining of the flowmeter, so special attention should be paid to it; there should be no strong electromagnetic field near the flowmeter ; There should be ample space nearby for installation and maintenance; if there is vibration in the measuring pipeline, there should be fixed supports on both sides of the flow meter. When measuring mixed liquids of different media, the distance between the mixing point and the flow meter should be at least 30×D (D flowmeter inner diameter) length In order to facilitate the cleaning and maintenance of the flowmeter in the future, a bypass pipeline should be installed; the above is the whole content of this article, you are welcome to inquire about the flowmeter selection and quotation of our factory.
