7 Installation
Prior to installation of the flow sensor, the system should be flushed and protection plugs/plastic diaphragms
removed from the flow sensor.
Correct flow sensor position (flow or return) appears from the front label of MULTICAL
®
. The flow direction is
indicated by an arrow on the flow sensor. Couplings and gaskets are mounted as shown in Figure 9.
Pressure stage ULTRAFLOW
®
: PN16/PN25, see marking. Flow sensor marking does not cover included accessories.
Temperature of medium, ULTRAFLOW
®
54: 15…130 °C/15…90 °C, see marking.
Mechanical environment: M1 - fixed installation with minimum vibration - and M2 - fixed installation with
considerable or high vibration level (flow sensor type 65-5-XXHX-XXX only).
Electromagnetic environment: E1 and E2 (housing / light industry and industry). The meter’s control cables must
be drawn at min. 25 cm distance from other installations.
Climatic environment: Must be installed in environments with non-condensing humidity (< 93% RH) as well as in
closed locations (indoors).
The ambient temperature must be within 5…55 °C.
Maintenance and repair: The flow sensor is verified separately and can, therefore, be separated from the calculator.
Direct connection of ULTRAFLOW
®
is only permitted to Kamstrup calculators on terminals 11-9-10, as shown in
paragraph 7.6 Electrical connections. Connection to different calculator types requires the use of a Pulse
Transmitter or Pulse Divider.
Replacement of supply and change of supply type is permitted in Pulse Transmitter/Pulse Divider. For battery supply
a lithium battery with connector from Kamstrup A/S must be used. Lithium batteries must be correctly handled and
disposed (see Kamstrup document 5510-408, ”Lithium batteries - Handling and disposal”).
It is permissible to replace output modules of Pulse Transmitter/Pulse Divider too.
Other repairs require subsequent reverification in an accredited laboratory.
Note: Please make sure that meter factors of flow sensor and calculator are identical.
At medium temperatures above 90 °C calculator and Pulse Transmitter/Pulse Divider must not be mounted on the
flow sensor. Instead wall mounting is recommended.
In order to prevent cavitation the back pressure at ULTRAFLOW
®
must be min. 1.0 bar (1.5 bar) at q
p
and min. 2.0
bar (2.5 bar) at q
s
for qp 0.6…2.5 m
3
/h (qp ≥ 3.5 m
3
/h). This applies to temperatures up to approx. 80
o
C.
ULTRAFLOW
®
must not be exposed to pressure lower than the ambient pressure (vacuum).
ULTRAFLOW
®
54 ought neither to be insulated nor wrapped as natural ventilation of the sensor is thereby prevented.
Should you after careful consideration decide to insulate ULTRAFLOW
®
after all, the electronics box must remain
uninsulated.
When the installation has been completed, water flow can be turned on. The valve on the meter's inlet side must
be opened first.
