Based on Faraday’s Law of Electromagnetic Induction, electromagnetic flowmeters are only applicable to conductive media with conductivity ≥ 5μS/cm. With the advantages of non-contact measurement, no pressure loss, and resistance to impurity interference, they are widely used in flow measurement scenarios across various industries, detailed as follows:
Municipal Water Supply & Wastewater Treatment Industry
Typical Applications: Flow measurement of raw water/clear water transmission in waterworks; inflow/outflow/return sludge flow monitoring in wastewater treatment plants; flow statistics of urban rainwater-sewage diversion pipe networks.
Adaptation Advantages: It can measure as long as the pipeline is full, without being affected by sediment and suspended solids in the medium. Large-diameter models (DN300–DN2000) are suitable for municipal pipe networks, and the pressure-loss-free design reduces energy consumption of pumping stations.
Petrochemical & Coal Chemical Industry
Typical Applications: Flow measurement of acid, alkali and salt solutions (e.g., sulfuric acid, caustic soda, ammonia water); monitoring of two-phase fluid flow containing solids (e.g., coal slurry, mineral slurry); feeding ratio control of chemical reactors.
Adaptation Advantages: Options of Hastelloy, titanium alloy electrodes and PTFE, PFA linings provide excellent corrosion resistance. There are no mechanical rotating parts, avoiding clogging or wear caused by particles in the medium.
Metallurgical & Mining Industry
Typical Applications: Flow monitoring of cooling water/slag flushing water in blast furnaces; flow measurement of mineral slurry/tailing slurry in mineral processing plants; flow control of electrolyte during smelting processes.
Adaptation Advantages: It can withstand high-concentration solid particles in the medium with excellent wear resistance. High-temperature resistant models can adapt to high-temperature media of 80–180℃, meeting the requirements of high-temperature working conditions in metallurgy.
Food, Beverage & Pharmaceutical Industry
Typical Applications: Batching measurement of liquid foods such as fruit juice, beer and dairy products; transmission monitoring of purified water/water for injection in pharmaceutical factories; flow control in the production process of condiments (soy sauce, vinegar).
Adaptation Advantages: Food-grade stainless steel electrodes combined with sanitary linings (e.g., EPDM) comply with FDA and GMP certifications, featuring easy cleaning and no residue. High precision (±0.3%R) meets the needs of accurate batching.
Papermaking & Printing and Dyeing Industry
Typical Applications: Flow measurement of pulp, black liquor and white water in paper mills; monitoring of dye solution and rinsing water flow in printing and dyeing factories.
Adaptation Advantages: It can measure high-viscosity and high-fiber-content media without clogging risk. Acid and alkali resistant linings adapt to the corrosiveness of printing and dyeing wastewater, ensuring a long stable operation cycle.
Power Industry
Typical Applications: Flow monitoring of circulating cooling water and desulfurization slurry (limestone slurry) in thermal power plants; flow measurement of coolant loops in nuclear power plants.
Adaptation Advantages: Large-diameter models with low pressure loss reduce the operating cost of circulating water pumps. The anti-electromagnetic interference design ensures stable operation around high-voltage electrical equipment.
Agricultural Irrigation & Water Conservancy Engineering
Typical Applications: Flow measurement of water delivery pipelines in farmland irrigation; monitoring of water resource scheduling in irrigation districts; flow monitoring of river sewage outlets.
Adaptation Advantages: Waterproof design (IP68) adapts to outdoor humid environments. Economical models offer high cost performance, meeting the large-scale flow measurement needs of agricultural irrigation.
