Features of Magnetic Flow Meter

  • Makes liquid flows visible by
    • Pulse output
    • Blinking LED (red/green)
  • No mechanical wear
  • No moving parts
  • Ease of mounting and operation
  • Mounting in any position
  • Free pipe cross section
  • No additional pressure drop
  • Fast response (<500 ms)
  • Insensitive with contaminated liquids
  • Ideal solution for interference free operation combined with a long-life cycle
  • Can be used in areas where flow sensors with moving parts cannot be applied
  • Wide independence to the inlet and outlet pipe creates the advantage to be able to install in compact machines with cramped confines

Connection to a PLC

Most digital PLC inputs are designed for connection to PNP signals. The MAG-VIEW™ has an NPN frequency signal with an integrated 2kΩ pull-up resistor. Its signal current of ~12 mA is recognised as a signal by the current PLC. Thus, operating a MAG-VIEW™ with a PLC should not present any problems. The frequency output of the MAG-VIEW™ should be attached to a digital input of the PLC.

Dimensions of Magnetic Flow Meter



The fields of application for this magnetic flow meter are diverse:
  • Can be used in areas where flow sensors with moving parts (paddle wheel, turbine sensors) cannot be applied due to contaminated media
  • Sensor is intended for continuously measuring of flow rates or for dosing / batching of electrically conductive liquids with a minimum of 50µS/cm
  • Water distribution
  • Chemical feed
Water and aquaous conductive liquids
