Energy Meter

Kamstrup energy meters are produced to MID Approval EN1434 to ensure the accuracy and quality for measurement.


MULTICAL® 603 is a very versatile meter in heat and cooling measurement as it can be applied as both heat, cooling and combined heat/cooling meter. The meter is 3-piece verified, so the calculator, flow sensor and temperature sensors can be replaced, if needed. The meter comes with a built-in Auto Detect function, making it possible to replace the ULTRAFLOW® when needed, without having to manually re-configure the calculator. The meter configuration is easily adapted to any installation via the 3 front keys. The versatile MULTICAL® 603 demands minimal installation requirements and provides maximum functionality at a competitive price.
