1. General information
Please read these instructions before installing the heat me-
ter. Kamstrup’s guarantee obligations do not apply in case
of incorrect installation.
Please note the following installation requirements:
Gland meters
Max. 16 bar
1.1 MID designations
Rated operation conditions/measuring ranges:
Temperature of medium in flow sensor: 0.1°C…30°C
Mechanical environment: M1 (fixed installation with minimum
vibration)
Electromagnetic environment: E1 (Domestic and light indu-
strial). Signal cables from the meter must be separated by at
least 25 cm distance to other installations.
Climatic environment: The installation shall be made in non-
condensing environments and in closed location (indoor). The
ambient temperature must be within 5…55°C.
Maintenance and repair:
The water supplier is allowed to change communication module
and battery. The flow part must never be separated from the
calculator. All repairs require a following re-verification on an
accredited laboratory.
Battery for replacement: Kamstrup type 66-00-200-100.

41 constantly monitors a number of important func-
tions. If a serious error occurs in the metering system or in the
installation, an “E” appears in the left side of the display and an
information code can be read by activating the front key until an
“E” appears in the right side of the display.

3. Mounting of flow part
Before mounting the flow part (flow sensor), flush the system
thoroughly and remove protection plugs/plastic membranes
from the flow sensor.
The flow direction is indicated by an arrow on the side of the
flow sensor.
There are no requirements for straight inlet, but we recommend
a straight inlet of 3…5
×
DN.
To prevent cavitation the operating pressure at the flow sensor
must be min. 1.5 bar at Q3 and min. 2.5 bar at Q4.
The flow sensor must not be exposed to pressures below
ambient pressures (vacuum).
