  Shannon MillerAug 13, 2025
  If the Kamstrup Measuring Instruments do not accumulate m³, first, check the flow sensor connection, using a pulse tester if necessary. Also, verify the flow sensor direction and inspect the system for air or cavitation from valves and pumps. If possible, increase the static pressure. As a last resort, replace the flow sensor or send the meter for repair.

  If the Kamstrup Measuring Instruments erroneously accumulate m³, ensure the meter factors of the calculator and flow sensor correspond to prevent erroneous programming. Also, check the system for air or cavitation from valves and pumps. If possible, increase the static pressure. If the issue persists, replace the flow sensor or send the sensor for repair.

  If the Kamstrup Measuring Instruments do not accumulate m³, first, check the flow sensor connection, using a PULSE TESTER if needed. Then, ensure the connection is correct and the flow sensor isn't inverted. Also, verify that there's no air in the sensor or cavitation from valves and pumps. Finally, if all else fails, the flow sensor might be faulty and require replacement or the meter needs repair.
