Electromagnetic Flow Meter for Conductive Liquids

The electromagnetic flow meter WUFS 905 is a smart metering solution designed for accurate volume flow measurement of conductive liquids in closed pipelines. Based on Faraday’s law of electromagnetic induction, it provides reliable flow measurement for water, wastewater, acids, alkalis, slurries, and other conductive liquids. With no moving parts, the meter offers minimal pressure loss, strong anti-interference performance, and excellent repeatability. The WUFS 905 is suitable for applications across water treatment, utilities, chemical processing, food and beverage, pharmaceutical, and other industrial sectors.

Electromagnetic Flow Meter Working Principle

The electromagnetic flow meter working principle is based on Faraday’s law of electromagnetic induction. As a conductive liquid passes through the magnetic field generated inside the meter, a voltage is induced that is proportional to the liquid velocity. This signal is processed to calculate the volumetric flow rate. Since the electromagnetic flow meter has no moving parts, it provides reliable operation, minimal pressure loss, and low mechanical wear, making it suitable for demanding industrial flow measurement applications. If your liquid is not conductive, or the pipe cannot be cut, a clamp on ultrasonic flow meter is the alternative to consider.

Electromagnetic Water Flow Meter Applications and Accuracy

An electromagnetic water flow meter is ideal for measuring conductive liquids such as clean water, wastewater, acids, alkalis, and slurries. The WUFS 905 offers an accuracy of ±0.5% and supports bi-directional flow measurement across pipe sizes from DN10 to DN2000. Its robust construction and IP65/IP68 protection options make it suitable for water treatment plants, utilities, chemical processing, and other industrial applications requiring dependable flow measurement. For plants that also need to measure steam or gas, the vortex flow sensor for gas, steam and liquid covers those media.

Applications of WUFS 905 Electromagnetic Flow Meter

The WUFS 905 is designed for flow measurement where water and other conductive liquids need to be monitored continuously through closed pipelines. It is well suited for Food & Beverage Plants, where engineers may need to track water, process-liquid and wastewater flow across production and utility systems. Its non-mechanical measurement principle makes it suitable for applications where dependable flow monitoring and low pressure loss are important.

In Pharmaceutical Plants, the WUFS 905 can be used to monitor suitable conductive liquids in process and utility lines. It can help plant and maintenance teams measure flow in different sections of the system, compare consumption and identify changes in operating conditions. The wide pipe-size range also allows the meter to be selected for different pipeline capacities and installation requirements.
