Questions and Answers

    Christopher SimpsonJul 27, 2025
    Why is there no energy accumulation in my Kamstrup Measuring Instruments?
    • E
      Elizabeth BrooksJul 27, 2025
      If your Kamstrup Measuring Instruments aren't accumulating energy (e.g., MWh) and volume (m3), the display might show an 'INFO' code. Refer to paragraph 7.8 to check the error indicated by the info code. If “INFO” = 0, ensure the flow direction matches the arrow on the flow sensor. If “INFO” = 4, 8 or 12, inspect the temperature sensors; replace the sensor set if they are defective.

    Why is my Kamstrup MULTICAL 402 accumulating volume but not energy?
    • N
      Nicole HallAug 8, 2025
      If your Kamstrup Measuring Instruments accumulate volume (m3) but not energy (e.g., MWh), the flow and return sensors might have been interchanged during installation or connection. Ensure the sensors are mounted correctly. Additionally, the heat/cooling cutoff might be configured too low. Reconfigure it at a suitable value or configure it at 180°C to disconnect the cutoff function.

    How to fix temperature reading that is a little too low on Kamstrup MULTICAL 402 Measuring Instruments?
    • C
      chavezrobinAug 15, 2025
      If the temperature indication is a little too low, or the accumulation of energy (e.g. MWh) is slightly too low on your Kamstrup Measuring Instruments, it might be due to bad thermic sensor contact, heat dissipation, or sensor pockets that are too short. Place the sensors at the bottom of the sensor pockets, insulate the sensor pockets, or replace them with longer pockets.

    What to do if my Kamstrup Measuring Instruments display is empty?
    • D
      Dustin SandovalAug 20, 2025
      If there is no display function (empty display) on your Kamstrup Measuring Instruments, the power supply might be missing. Change the battery or check the mains supply. Verify that the supply plug provides 3.6 VDC.
