Using Electromagnetic Flowmeters in the Wastewater Industry

Wastewater treatment facilities must effectively filter toxins and pathogens from inflowing water to produce high-quality drinking water. They do so via complex operational processes that involve a wide range of flow measurement tasks.

Since these facilities have the all-important task of making dirty water once again fit for human consumptionCalibration-rig-factory-DN250-2400, they require highest possible flow water accuracy and reliability without risking their long-term stability or creating too many expenses.

Magnetic flowmeters use Faraday’s Law of Electromagnetic Induction to help determine the flow of liquid in a pipe. The flowmeter generates a magnetic field and channels it into the liquid as it flows through the pipe.

Benefits of Flowmeters in the Wastewater Industry

Flowmeters benefit wastewater industry applications by providing high accuracy, long lifespans, trouble-free installation, and low cost of ownership. Flowmeters can measure raw wastewater, effluent water, and sludge with improved uptime and reduced pipe shutdown.

Many flowmeter manufacturers also calibrate their products to the user’s specific application before shipping, making implementation easier. Furthermore, these systems generally require minimal maintenance after they’re installed.

Flowmeters don’t use moving parts, which improves their reliability. They also can achieve accuracies ranging from 0.5% to 2.0% of the reading.

Products We Offer

At Endress+Hauser, we offer a wide range of flowmeters to help you choose the best one for your needs. Among our offerings are:


  • Electromagnetic flowmeters can measure and monitor the flow of conductive liquids during processes that include filling, dosing, and custody transfer. Low-maintenance flowmeters take readings independently of pressure, density, temperature, and viscosity.
  • Coriolis mass flowmeters, which measure mass flow, density, temperature, and viscosity at the same time. They’re useful in applications in the life science, petroleum, chemical, and food industries. They also can gather readings without the need for inlet and outlet runs.
  • Ultrasonic flowmeters allow for versatile, reliable measurements of fluid flow rates with diameters up to DN 4,000. They’re used in applications that require guaranteed accuracy. Ultrasonic flowmeters have long service lives without requiring much maintenance.
  • Vortex flowmeters are usable across liquids, gases, and steam. These flowmeters take measurements in industries including power generation and heat supply. With high long-term stability, the instruments aren’t affected by changes in fluid characteristics and operate at temperatures ranging from –200 to 450°C based on the client’s needs.
  • Differential pressure measurement sensors measure high hydrostatic pressure and low head pressure values in the process industry. The systems eliminate the traditional safety risks and mechanical issues inherent the designs of other devices.
  • Thermal mass flowmeters measure the mass of entities including industrial gases, compressed air, and aqueous fluids in applications that include process control and leak detection. The sensors have high sensitivity on the low end, and they can quickly respond to flow changes. They also have the ability to measure and display flow and temperature at the same time.
