Kamstrup Multical 602

RHI MID Class 2 Heat Meters


Kamstrup’s Multical 602 is an all-purpose heat calculator for heat and cooling together with almost any kind of pulsed flow meters and with 2 or 4 wired temperature sensor pairs.

Kamstrup Multical 602 Heat Meter

When used together with Kamstrup’s Ultraflow 54 ultrasonic flow meter more advanced functions are available.

The Kamstrup Multical 602 is a compact heat meter which measures the exact consumption with a high level of accuracy.

The Kamstrup heat meter is maintenance-free and has a long lifetime with minimal yearly operating costs.

Kamstrup’s Multical 602 is used for heat, cooling and combined heat / cooling measurement in all water-based systems with temperatures from 2°C to 180°C for heat and 2°C to 50°C for cooling.

The Multical 602 is used as heat meter together with the Ultraflow 54 flow meter and two temperature sensors.

Flow sizes range from qp 0.6 m³/h to 1,000 m³/h. In cooling applications up to qp 100 m³/h the meter is connected to the Ultraflow 14 flow meter and temperature sensors, whereas the meter is used together with the Ultraflow 54 in cooling applications from qp 150 m³/h to qp 1,000 m³/h.

The heat calculator can be used with flow parts up to qp 3,000 m³/h.

The Kamstrup Multical 602 is characterized by its complete range of communication modules and integral RTC (Real Time Clock), which make it easy to fit the meter into all applications independent of reading type.

The heat meter can be fitted with LON, SIOX, M-Bus, a data module and the new solutions Metasys N2 and Ethernet/IP for wired communication.

If the energy meter is to be integrated into a wireless network, you can select radio, Wireless M-Bus, Zigbee or one of Kamstrup‘s new modules: GSM/GPRS or High Power RadioRouter.
