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.
Please note:
ULTRAFLOW
®
54 may be lifted in the lifting rings only.
Pressure stage of 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:
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 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 re-verification 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.
Note:
Please 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.
