up to 16 years oldDescription
MULTICAL® 603 is a universal energy calculator that, in combination with 1 or 2 ULTRAFLOW® flow meters and 2–3 temperature sensors, functions as a heat meter, cold meter, or combined heat/cold meter. It is designed for precise measurement, long service life, and easy integration into remote reading and control systems. Auto Detect simplifies maintenance, and a rich set of communication modules allows for painless upgrades and integrations into AMR/AMI/SCADA environments.

Installation and design
- IP65, weight ~450 g; ambient temperature 5…55 °C (indoor installation).
- Recommendation: at ambient temperatures below or >90 °C in the flow meter – wall mounting of the calculator.
Approvals and standards
- EN 1434, MID 2014/32/EU (DK-0200-MI004-040); DK-BEK 1178 (cooling); environmental classes A/C, M1/M2, E1/E2.
MULTICAL® 603 operates with low ULTRAFLOW® flow rates (from 0.6 m³/h), making it suitable for apartments and residential buildings; higher flow rates are also available for building/industrial systems. Contact us for selection of ULTRAFLOW® size, communication modules, and power supply according to the project.
