  • Page 6: Operating Principle

    MIM- 6. Operating principle 6.1 General The new KOBOLD MIM Flowmeter is designed to measure and monitor small and medium flows of conductive fluids in piping. The device works on the magnetic-inductive measuring principle. According to Faraday's law of induction, a voltage is induced in a conductor moving in a magnetic field.

    MIM- 7. Mechanical connection 7.1 Check operating conditions  flow rate  max. operating pressure  max. operating temperature In general, MIM is subjected to the same loads as the piping into which it is installed. The MIM 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.

  • Page 15: Menu Mode

    MIM- 9.3 Menu Mode In menu mode, all device parameters can be set. The individual parameters are arranged in menu groups by function. While the menu mode is activated, the signal processing and the outputs are still active in the background. However, all display parameters and outputs are updated after exiting the menu mode or in the measuring mode.

  • Page 16: Device Configuration

    The flowmeter MIM is pre-configured in factory. Changing the parameters "Measuring range" and "Sensor constant" or "K factor" is therefore not permitted. The adjustment of these parameters is only possible on the part of Kobold- factory. In the event of subsequent changes to volume or throughput units, the dependent parameters are converted and adjusted accordingly.

  • Page 17: Display

    MIM- 10.3 Display 10.3.1 Refresh Parameter "Refresh" defines the time interval within which the measuring variables are displayed. The "Refreshrate" can be increased in steps of 0.5 sec. to 10 sec. An increase in the refresh rate time causes an increased "filtering" of the display value.
  • Page 18 MIM- The called hotkey function remains permanently activated and can only be left by pressing the key .
