1. Installation
Prior to installation of the flow sensor, the system should be flushed.
Correct flow sensor position (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.
Note
: ULTRAFLOW®
54 may be lifted in the lifting rings only.
Pressure stage ULTRAFLOW®
54
: PN25
Temperature of medium, ULTRAFLOW® 54
: 2…150°C/2…50°C.
See marking on label.
Mechanical environment
: M1 and M2 (fixed installation with minimum vibration
and fixed installation with considerable or high vibration level respectively). See
marking on label.
Electromagnetic environment
E1 and E2 (housing/light industry and industry
respectively). See marking on label.
The meter’s signal cables must be drawn at min. 25 cm distance to other
installations.
Climatic environment
: Can 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 flow sensor is verified separately and can, therefore,
be separated from the calculator. It is permitted to replace the supply and change
the supply type. 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”).
Other repairs require subsequent reverification in an accredited laboratory.
If ULTRAFLOW® 54 is connected via a galvanically coupled output module, the flow
sensor may be connected to a Kamstrup MULTICAL® calculator only.
If other calculator types are connected, ULTRAFLOW® 54 must be fitted with a
galvanically separated output module and a power supply of its own.
Please note:
Make sure that pulse figures of flow sensor and calculator are identical.
The steel tube between flow sensor housing and electronics box may not be
disassembled.
At medium temperatures above 90°C (T
med
> 90°C) or medium temperature
more than 5°C below ambient temperature (T
med
< T
amb
- 5°C) the flow sensor's
electronics box must be mounted via the enclosed distance piece. Alternatively, the
electronics box can be wall mounted at a distance of minimum 170 mm from the
sensor.
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
o
C.
When the installation has been completed, water flow can be turned on. The valve
on the inlet side must be opened first.
