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 position of the flow sensor (flow or return) appears from the front label of MULTICAL
®
. The flow direction is
indicated by an arrow on the side of the flow sensor.
Glands and gaskets are mounted as shown in Figure 15, page 26.
Pressure stage of 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.
Temperature of medium, ULTRAFLOW
®
34: 2…130 °C/2…50 °C, see marking.
Mechanical environment: M1 (fixed installation with minimum vibration).
Electromagnetic environment: E1 and E2 (housing/light industry). The meter’s signal cables must be drawn at
min. 25 cm distance from other installations.
Climatic environment: Installation must take place in environments with non-condensing humidity as well as in
closed locations (indoors). However, ULTRAFLOW
®
34 may be installed in environments with periodically
condensing humidity.
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.
ULTRAFLOW
®
can only be direct connected to Kamstrup’s calculators on terminals 11-9-10, as shown in paragraph
7.6 Electrical connection of ULTRAFLOW
®
and MULTICAL
®
. Connection to other types of calculators requires the use
of a Pulse Transmitter or Pulse Divider.
It is permissible to replace the supply and change the supply type 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 of (see Kamstrup document 5510-408, ”Lithium batteries - Handling and disposal”).
It is also permissible to replace the output module in Pulse Transmitter/Pulse Divider
Other repairs require subsequent re-verification in an accredited laboratory.
Note: Please make sure that the meter factor is identical on flow sensor and calculator.
At medium temperature above 90 °C, the use of flange meters is recommended.
At medium temperature above 90 °C or at medium temperature more than 5 °C below ambient temperature
(T
med
< T
amb
- 5 °C), calculator and Pulse transmitter/Pulse divider may 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. 1.5 bar at q
p
and min. 2.5 bar at q
s
.
This applies to temperatures up to approx. 80 °C.
ULTRAFLOW
®
must not be exposed to pressure lower than the ambient pressure (vacuum).
ULTRAFLOW
®
54 should not be insulated or enclosed as the natural ventilation around the meter is prevented.
ULTRAFLOW
®
34 should not be insulated or enclosed as condensation around the meter will be trapped.
If, after careful consideration, ULTRAFLOW
®
is insulated anyway, the electronics housing must remain uninsulated.
When the installation has been completed, water flow can be turned on. The valve on the inlet side must be
opened first.
