Mechanical environment
M1 (fixed installation with minimum vibration).
M2 (significant or high level of vibration and shock).
Electromagnetic environment
E1 and E2 (domestic/light industry and industry). The meter’s signal cables must be drawn at min.
25 cm distance to other installations.
Climatic environment
Must be installed in environments with non-condensing humidity as well as in closed locations
(indoors). The ambient temperature must be within 5…55 °C.
Maintenance and repair
The district heating supplier can replace communication module, battery and temperature sensor
pair. The flow sensor may also be replaced, but must be suitable for mixed fluid applications and
possible sub-zero temperatures.
MULTICAL® 6M2, type 6M2-G/H must be connected to a temperature sensor pair type Pt500.
MULTICAL® 6M2, type 6M2-G can be connected to flow sensor type electronic pick-up or flow sen-
sors with reed switch output.
MULTICAL® 6M2, type 6M2-H must be connected to a flow sensor with 24 V active pulse output.
Irrespective of flow sensor type, “pulses/litre” must be identical in flow sensor and calculator.
Battery for replacement
Kamstrup type 1606064.
