Magnetic inductive flow sensors with threaded connection / Metal version

型號:Type induQ VMI
  • Robust metal housing for high temperatures and pressures
  • wide measuring range 1:60 (1:50) and very good measuring accuracy
  • frequency or analogue and frequency output
  • supplied with SIKA works calibration certificate
  • The sensors of the induQ® VMI series allow a flow- / volumetric flow measurement of electrically conductive liquids without moving parts. These are the ideal flow sensors when it comes to accuracy and reliability.

    The SIKA VMI 07 is used, among other things, for cooling processes in machine and plant construction or in building technology.

    The intelligent flow sensors of the induQ® series operate according to the induction principle: the measuring pipe is surrounded by a magnetic field (B). If an electrically conductive medium with the flow rate to be determined (Q) flows through the measuring pipe and thus enters the magnetic field at a right angle, a charge (U) is induced into the medium which is proportionate to the mean flow velocity and tapped by two electrodes. For an output signal which is proportionate to the flow rate, there are two versions available:

    • frequency output signal (standard)
    • analogue and frequency output signal (option)

    The pulse rate can be configured at the factory depending on the type.
