Title: Applications of Electromagnetic Flowmeters and Ultrasonic Flowmeters in Different Industries


In the industrial world, accurate flow measurement is of utmost importance. Electromagnetic flowmeters and ultrasonic flowmeters are two widely used instruments, each with unique features and a broad range of applications.


Electromagnetic Flowmeters

  • Water Treatment Industry:
    • In municipal sewage treatment plants, electromagnetic flowmeters are employed to monitor the flow of sewage in various treatment stages. For instance, in the influent and effluent pipes of primary sedimentation tanks, biological treatment tanks, and secondary sedimentation tanks in a sewage treatment plant in Beijing, electromagnetic flowmeters are installed. This helps in evaluating the performance of the treatment process and detecting anomalies promptly.
    • In waterworks, they measure the flow of raw water intake, water in different process sections, and the final treated water. A waterworks in Sydney uses electromagnetic flowmeters in the raw water and treated water pipelines to ensure precise control and stable supply.
  • Chemical Industry:
    • In a PVC manufacturing plant, electromagnetic flowmeters measure the flow of vinyl chloride monomer, water, and additives to maintain the exact formulation for consistent product quality.
    • In a pesticide production facility, they control the flow of pesticide concentrates and solvents, which is crucial for the potency and effectiveness of the final product. An electromagnetic flowmeter in the reaction kettle feed pipe of a pesticide factory in France ensures accurate dosing and high-quality production.
  • Petroleum and Petrochemical Industry:
    • At the wellhead in an oilfield, electromagnetic flowmeters measure the output of crude oil. In the Middle East, some oilfields have installed them to manage production and estimate reserves.
    • In refinery product pipelines, they accurately measure the flow of gasoline, diesel, and kerosene for proper metering and sales. A refinery in Texas uses electromagnetic flowmeters in the loading pipelines to avoid measurement errors and economic losses.
  • Food and Beverage Industry:
    • In a brewery, electromagnetic flowmeters handle the flow of wort, beer, water, and carbon dioxide, contributing to the control of the brewing process and product quality. A brewery in Munich uses them in the mashing, fermentation, and bottling processes to ensure the perfect taste and quality of the beer.
    • In a juice production line, they measure the flow of juice concentrates, water, and additives to maintain the correct recipe. A juice factory in Florida uses electromagnetic flowmeters in the blending and filling processes to enhance production efficiency and product consistency.
  • Pharmaceutical Industry:
    • In drug manufacturing, electromagnetic flowmeters measure the flow of raw materials, solvents, and intermediate products. In a pharmaceutical company in Switzerland, they are used in the fermentation process of antibiotic production to ensure stable operation and high-quality output.
    • In traditional Chinese medicine extraction, they control the flow of extraction liquids and solvents. A TCM factory in China installs electromagnetic flowmeters in the extraction tank feed pipes to improve extraction efficiency and quality.
  • Metallurgical Industry:
    • In the iron-making process of a steel mill, electromagnetic flowmeters measure the flow of molten iron, slag, and cooling water. A steel company in South Korea uses them in the blast furnace taphole and cooling water pipes to adjust process parameters and ensure safe operation.
    • In non-ferrous metal smelting, they handle the flow of molten salts and metal melts. An aluminum smelter in Canada uses electromagnetic flowmeters in the electrolytic cells to ensure stable electrolysis and high-quality aluminum production.

Ultrasonic Flowmeters

  • Urban Heating System:
    • In urban central heating networks, ultrasonic flowmeters measure the flow of hot water for heat metering and energy consumption analysis. In a city in Russia, ultrasonic flowmeters are installed in key points of the heating network to optimize the system's operation.
    • In district heating substations, they measure the secondary side hot water flow to monitor the substation's performance and residents' heat consumption. A district heating substation in Sweden uses ultrasonic flowmeters to detect pipeline leaks and ensure heating safety.
  • Natural Gas Industry:
    • In long-distance natural gas pipelines, ultrasonic flowmeters are used for accurate measurement. The Nord Stream pipeline project employs ultrasonic flowmeters for reliable metering and safe transportation.
    • In urban gas distribution networks, they measure gas flow for utility management and customer metering. A gas company in the UK installs ultrasonic flowmeters in gas regulator stations and customer endpoints to improve management and service quality.
  • Water Conservancy Industry:
    • In the spillway of a large water conservancy project, ultrasonic flowmeters measure the flood discharge flow. The Three Gorges Dam uses ultrasonic flowmeters in the spillway to support safe operation and flood control scheduling.
    • In irrigation canals, they measure the flow of irrigation water for efficient water resource allocation. An irrigation district in India installs ultrasonic flowmeters in the canals to enhance water use efficiency.
  • Environmental Protection Industry:
    • In industrial wastewater discharge monitoring, ultrasonic flowmeters measure the wastewater flow along with water quality monitoring equipment. An industrial park in Japan installs them at the wastewater discharge outlet for comprehensive monitoring and management.
    • In urban stormwater drainage systems, they measure the flow of rainwater to support drainage system planning and design. A city in Singapore installs ultrasonic flowmeters in key points of the stormwater network to optimize the design and improve flood prevention capabilities.
