The MJK MagFlux® is a versatile electromagnetic flowmeter that can be deployed in drinking water and wastewater.

  • Overview

    The MJK MagFlux® 7200 is a best-in-class electromagnetic flowmeter designed for use in drinking water and wastewater applications. This mag meter is extremely reliable and uses the principle of Faraday’s law to measure flow. It utilizes an automatic self-cleaning function to help keep electrodes clean for more extended periods, increasing the MagFlux’s reliability.

    • Precise Measurement - The MagFlux maintains high accuracy at low flow rates, keeping within .25% accuracy down to 0.2 m/sec.
    • Modular Design - The MagFlux display, converter, and flowmeter can be deployed in a variety of configurations. The display can operate up to four flowmeters and can be mounted up to 1000 m from the sensor.
    • Built-in Data Logger -The MagFlux is equipped with a data logger that can record up to 345,000 data points.
    • Versatile Installation - The MagFlux can easily be installed where other flowmeters can’t. With a minimum inlet run of 3x DN and an outlet run of 2x DN, the MagFlux can easily be deployed in difficult places.
    • NSF-61 Approved - The MagFlux 7200 (in select configurations) is able to be deployed in applications that come into direct contact with potable water. 

    The MagFlux 7200 is available in:

    Sizes: 3/4" to 48"
