Kamstrup Heat Meter - Multical 402 RHI Approved MID Class 2 

Kamstrup’s Multical 402 is a compact heat meter which measures the exact energy consumption with a high level of accuracy. The unit is maintenance-free and has a long lifetime with minimal yearly operating costs.

The Kamstrup Multical 402 heat meter can be used for heat, cooling and combined heat/cooling measurement in all water-based systems with temperatures from 2 to 160°C. It consists of a heat calculator, a flow meter and two temperature sensors. It is simple to install, read and verify.

Kamstrup Multical 402 Heat Meter

The Kamstrup Multical 402 heat meter has been developed for measurement of energy consumption in family and multiple occupancy housing, housing associations, blocks of flats and small industry.

The flow meter range for the Multical 402 energy meter comprises of the sizes 0.6 – 15 m³/h, and the supply options are 230 or 24 VAC mains module, 2xAA-cell battery, or D-cell battery with up to 16 years’ lifetime.

 

 

Kamstrup Multical 402 Heat Meter

The Kamstrup Multical 402 heat meter  is fitted with a connector for the supply and is easy to change battery or mains supply.

Kamstrup’s Multical 402 receives pulses from up to two connected hot or cold water meters and carries out remote accumulation of energy and volume via pulse outputs.

If you change from pulse input to pulse output, the heat meter is automatically configured for pulse inputs and pulse outputs respectively – without manual reconfiguration.
