Kamstrup Multical 6M2 Heat Meter – Ultrasonic Heat Meters MID Class 2

Kamstrup Multical 6M2 Heat Meter

MID Class 2 Heat Meter

Kamstrup Multical 6M2 heat meter is an all-purpose energy calculator for mixed fluid applications which works together with a pulsed flow sensor and a pair of 2-wire temperature sensors.

The Kamstrup Multical 6M2 is used for heat and cooling measurements in all mixed fluid-based systems with medium temperatures from -40 °C to 140 °C.

The Multical 6M2 is used together with a flow sensor and two temperature sensors (Pt500 sensors).

The calculator can be used with different types of flow sensors suitable for mixed fluids and can be used with flow parts up to up to qp 3,000 m³/h.

Product Benefits

Designed for mixed fluids the Multical 6M2 is suitable for use with most common antifreeze liquids (tyfocor, antifrogen, ethylene- & propylene glycol) used in industrial, commercial and domestic applications.

The Kamstrup Multical 6M2 can be fitted with a wide range of communication modules to allow data integration with Building Management Systems through pulsed outputs, M-Bus, LonWorks, BACnet or Modbus.

Operating costs are minimal as the meter is fitted with a battery that has an approximate battery life of 13 years.

No need for to configure at installation as this single box solution contains g a preprogrammed integrator, a mechanical flow meter and temperature sensors.

MID Approved CLASS 2

The Measuring Instruments Directive (MID) is a European directive (2004/22/EC) that harmonises the requirements of 10 different measuring instrument types, including gas meters and heat meters. MID approved heat meters will have passed specific conformity assessment procedures and have MID markings which allow the instruments to be used in any EU member state.

Heat meters to be used for the Non-Domestic RHI in the UK must also comply with MID Class 2.

Product Specifications

Calculator Functions – Energy calculation by the heat meter is carried out on the basis of the formula stated in prEN 1434-1:2009 . This uses the international temperature scale issued in 1990 (ITS-90) and the pressure definition of 16 bar.

Kamstrup Multical 6M2 operates with two different energy formulas E1 and E3. These formulae are calculated in parallel with each integration no matter what the configuration of the energy meter.

In addition the calculator can be used to calculate and display flow measurement, power measurement, maximum flow and power, temperature measurement, user, tech and set-up loops.

Communication – The Kamstrup Multical 6M2 communication modules make it easy to fit the meter into various applications.

Data communication is KMP protocol with CRC16 used for optical communication and for top and base modules.
