Siemens SITRANS FM MAG 5100W flow sensors are designed for monitoring flow in water, sewage, and sludge applications. It comes standard with an epoxy-coated carbon steel body, Hastelloy C-276 integrated grounding and measuring electrodes, and EPDM or NBR liner, and is available in sizes from 1/2" to 78" diameters.

The MAG 5100W's coned liner design provides increased low flow accuracy for water leak detection. The rugged unit suitable for direct burial and constant flooding, and when ordered with an EPDM liner, can be used for drinking water applications. Key applications include water abstraction, water and wastewater treatment, water distribution and leak detection, custody transfer water meters, irrigation, filtration, and industrial water applications.
