Electromagnetic flowmeter is a velocity meter that measures the volume flow of conductive media. It is a commonly used flowmeter in metallurgy, papermaking, drainage, sewage treatment and other industrial fields. Compared with other flow meters, it has obvious advantages. The electromagnetic water meter is designed specifically for the water industry to meet the requirements of urban water supply to ensure accurate water fee calculation. It is mainly used to measure the volume flow of conductive liquid in closed pipelines. The external installation environment has certain requirements and is widely used in places where there is no power supply on site, such as raw water, water supply, sewage treatment, water conservancy projects and other industries.The specific requirements are as follows:1. The split electromagnetic flowmeter should not be installed in places where the temperature changes greatly or is subject to high-temperature radiation from the equipment. If it should be installed, it must be installed with heat insulation and ventilation measures.2. The flowmeter should be installed indoors. If it should be installed outdoors, it should avoid rain, flooding and sun exposure, and moisture-proof and sun-proof measures should be taken.3. The flowmeter should not be installed in an environment containing corrosive gas, and ventilation measures should be taken when installing it.4. For the convenience of installation, maintenance, and maintenance, ample installation space is required around the flowmeter.5. The installation site of the flowmeter should avoid magnetic fields and strong vibration sources. If the pipeline vibrates greatly, there should be fixed pipeline supports on both sides of the flowmeter.Main advantages:1. It is suitable for measuring liquid-solid two-phase fluids containing solid particles or fibers, such as paper pulp, coal water slurry, mineral slurry, mud and sewage.2. The volume flow measured by the electromagnetic flowmeter is actually not affected by fluid density, viscosity, temperature, pressure and conductivity.3. It is easy to choose the material varieties of the parts in contact with the fluid, and can be applied to corrosive fluids.4. The front straight pipe section requires lower requirements.5. The caliber range is wider than other types of flow meters, from a few millimeters to 3m. It can measure the positive and negative two-way flow, and also can measure the pulsating flow.6. The electromagnetic flowmeter has a large measuring range, usually 20:1～50:1, with a wide range of optional flow rates. The liquid velocity of the full scale value can be selected within 0.5～10m/s.
