MID designations
Permissible operating conditions / measuring ranges:
Calculator
q
: 2°C…180°C
DΘ
: 3K…170K
Temperature sensor pair
q
: 10°C…150°C
DΘ
: 3K…140K
Flow sensor
q
: 15°C…130°C
Mechanical environment:
M1 (fixed installation with minimum vibration).
Electromagnetic environment:
E1 and E2 (housing/light industry and industry). The meter’s control 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 is verified separately and can, therefore,
be separated from the calculator.
Other repairs require subsequent reverification in an accredited laboratory.
MULTICAL® 602, type 602-B/C/D must be connected to a temperature sensor pair
type Pt500.
MULTICAL® 602, type 602-A must be connected to a temperature sensor pair type
Pt100.
Battery for replacement: Kamstrup type 66-00-200-100.
MULTICAL® 602, type 602-A/B/C can be connected to flow sensor type
ULTRAFLOW®, electronic pick-up, or flow sensors with reed switch output.
MULTICAL® 602, type 602-D 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.
