    MIK  Operating Instructions 4. Regulation Use Any use of the Compact Magnetic-Inductive Flow Meter, model: MIK, which exceeds the manufacturer’s specifications, may invalidate its warranty. Therefore, any resulting damage is not the responsibility of the manufacturer. The user assumes all risk for such usage.

  • Page 4: Operating Principle

    It is necessary for the correct function of the device that the current canal is always filled completely with medium. As of a minimum electrical conductivity of 30 µS/cm the MIK works within the guaranteed margins of error. The conductivity of the medium is continuously monitored by the device’s electronic system.

    5.4 Measuring electrodes The electrodes used with the MIK have a galvanic pick-off. They are in direct contact with the fluid and are fitted opposite one another, and insulated from the measuring tube. The standard electrodes are made of 1.4404 stainless steel or Hastelloy C4.

     max. operating pressure  max. operating temperature In general the MIK is subjected to the same loads as the piping into which it is installed. The MIK should therefore be kept away from extreme loads, such as pressure surges with strong, dynamic pipe movements, vibrations in the proximity of centrifugal pumps, high temperature media, flooding etc.
