Waste water is used for pipeline discharge. Most of them choose electromagnetic flowmeter to measure. Because there is no obstacle in the sensor, there is no fear of debris in the medium, but it is necessary to pay attention to the medium must be full. If the tube is not full, it must be piped to sink a section. Pipeline to ensure that the flowmeter is full. Note that the flowmeter cannot be installed at the drain of the pipe. The length of the straight pipe should meet the requirements of the flowmeter.
Electromagnetic flowmeters are primarily used to measure volumetric flow in conductive liquids and slurries in closed conduits.
The electromagnetic flowmeter measurement principle is based on Faraday's electromagnetic induction law. The pipeline electromagnetic flowmeter consists of a sensor and a converter. The sensor is mounted on the measuring pipeline. The converter can be combined with the sensor and is called an integrated electromagnetic flowmeter. When it is installed within 30 meters or within 100 meters of the sensor, the connection between the two is called a separate electromagnetic flowmeter.
In the electromagnetic flowmeter, the conductive medium in the measuring tube is equivalent to the conductive metal rod in the Faraday test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows, an induced voltage is generated. The two electrodes inside the pipe measure the induced voltage generated. The measuring tube is electromagnetically isolated from the fluid and the measuring electrode by a non-conductive inner liner (rubber, Teflon, etc.).
Electromagnetic flowmeters are used to measure the flow of conductive fluids in the departments of tap water, steel, petroleum, chemical, electric power, industry, water conservancy, water resources, water resources, etc., and can also measure corrosive conductive liquids such as acids, alkalis, and salts.
