1Gener l description
ULTRAFLOW
®
54 DN15 -25 is a static flow sensor based on the ultrasonic measuring principle. It is primarily
used as a volume flow sensor for energy meters such as MULTICAL
®
. ULTRAFLOW
®
54 DN15 -25 has been
designed for use in heating and cooling installations where water is the heat-bearing medium.
ULTRAFLOW
®
54 DN15 -25 employs ultrasonic measuring techniques and microprocessor technology. All
calculating and flow measuring circuits are collected on one single board, thus providing a compact and rational
design and, in addition, exceptionally high measuring accuracy and reliability is obtained.
The volume is measured using bidirectional ultrasonic technique based on the transit time method, with proven
long-term stability and accuracy. Four ultrasonic transducers are used to send sound signals both against and
with the flow. The ultrasonic signal travelling with the flow reaches the opposite transducer first. The time
difference between the two signals can be converted into flow velocity and thereby also volume.
A three-wire signal cable is used to connect ULTRAFLOW
®
54 DN15 -25 to the Kamstrup MULTICAL
®
calculator.
The cable supplies the flow sensor and also transfers the signal from sensor to calculator. A signal corresponding
to the flow – or more correctly, a number of pulses proportional to the water volume flowing through – is
transmitted.
ULTRAFLOW
®
54 DN15 -25 is available with internal supply, e.g. if the distance between MULTICAL
®
and
ULTRAFLOW
®
is 1 meters or more. If ULTRAFLOW
®
54 DN15 -25 is used for other equipment (e.g. other brands
of calculators), the sensor must be fitted with a galvanically separated output module and a supply of its own.

6Pressure loss
Pressure loss in a flow sensor is stated as max. pressure loss at q
p
.
According to EN 1434 max. pressure loss must not exceed .25 bar unless the energy meter includes a flow
controller or functions as pressure reducing equipment.
The pressure loss in a meter increases with the square of the flow and can be stated as:
pkvQ ∆×=
where:
Q = volume flow rate [m³/h]
kv = volume flow rate at 1 bar pressure loss
∆ p = pressure loss [bar]

7Inst ll tion
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.
Ple se note: ULTRAFLOW
®
54 may be lifted in the lifting rings only.
Pressure st ge of ULTRAFLOW
®
54: PN25
Temper ture of medium, ULTRAFLOW
®
54: 2…15 °C/2…5 °C. See marking on label.
Mech nic l environment: M1 and M2 (fixed installation with minimum vibration and fixed installation with
considerable or high vibration level respectively). See marking on label.
Electrom gnetic 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.
Clim tic 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.
M inten nce nd rep ir: 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 551 -4 8, ”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 9 °C (T
med
> 9 °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 17 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. 8
o
C.
When the installation has been completed, water flow can be turned on. The valve on the inlet side must be
opened first.

7.1 Inst ll tion ngle of ULTRAFLOW
®
54
ULTRAFLOW
®
can be installed horizontally,
vertically, or at an angle.
ULTRAFLOW
®
54 is normally installed
horizontally, with the lifting rings oriented
vertically. The ultrasound paths in the flow
sensor tube will thus be vertical, which is
optimal in connection with possible
stratification of the medium.
7.1.1 Mounting ULTRAFLOW
®
54 in lifting ring
ULTRAFLOW
®
54 can be mounted hanging from one of the two lifting rings depending on required flow direction.
The enclosed distance piece can be used to secure optimal position of the electronics box. (See paragraph 7.2 )

7.2 Mounting of ULTRAFLOW
®
54 electronics box
At medium temper ture below 90°C (T
med
< 90°C) nd t medium temper ture less th n
5°C below mbient temper ture (T
med
> T
mb
- 5°C) the electronics box can be mounted
directly on the flow sensor housing via the factory mounted fitting.
If the flow sensor is vertically mounted, the cable connections of the electronics box will
be horizontally oriented. This is permitted. If the cable connections should preferably
point downwards, the electronics box can be mounted via the enclosed distance piece,
which moves the box approx. 17 mm away from the flow sensor housing. Alternatively,
a shorter distance piece, which only moves the box approx. 45 mm away from the flow
sensor housing, can be used. The short distance piece must be ordered separately
(6561-332).
At medium temper ture bove 90°C (T
med
> 90°C) the temperature is too high for the
electronics box to be mounted directly on the flow sensor housing.
Therefore, the electronics box must be mounted via the enclosed distance piece. The
cable connections must always point downwards. (See paragraph 7.2.1 )
Alternatively, the electronics box can be wall mounted as long as the distance to flow
sensor housing and pipe installation is minimum 17 mm.
It can also be an advantage to use the enclosed distance piece if the flow sensor
housing is insulated and the electronics box must be removed from the insulation.
If the required position of the electronics box differs from standard position, the
distance piece can be mounted with the enclosed collar band around the flow sensor
housing. However, please note that the cable connections must always point
downwards. (See paragraph 7.2.1 )
At medium temper ture more th n 5°C below mbient temper ture (T
med
< T
mb
- 5°C)
(typically in cooling installations) it is important to take action to avoid condensation
in the electronics box.
Therefore, the electronics box must be mounted via the enclosed distance piece.
The cable connections must always point downwards. (See paragraph 7.2.1 ).
Alternatively, the electronics box can be wall mounted as long as the distance to flow sensor housing and pipe
installation is minimum 17 mm.
Furthermore, when mounting the electronics box please make sure that the cable connections on the box are at a
higher level than the cable connection on the flow sensor housing.
By vertical mounting of ULTRAFLOW
®
54 in a riser this can be secured by mounting the distance piece by means of
the collar band as shown in
Figure 8 .

If ULTRAFLOW
®
54 is mounted horizontally, the electronics box can be mounted on the distance piece by means of
the collar band. The distance piece can then be turned upwards until the cable connections on the electronics box
are in a higher position than the cable connection on the flow sensor housing. See Figure 9 .
Alternatively, the electronics box can be wall mounted at a suitable distance to the installation (minimum 17
mm).
7.2.1 Orient tion of flow sensor electronics box
Mounting the electronics box, the cable connections must always be horizontally or downwards oriented in order
to avoid the risk of water and condensation being led into the electronics box via the cables.
This is especially important in humid environments, when ULTRAFLOW
®
54 is used as cooling sensor or if the
medium temperature can become more than 5°C lower than the ambient temperature (T
med
< T
amb
- 5°C).
Furthermore, steel tube and wires must in general hang freely downwards after the cable connections to form a
drip nose for drainage of water and condensation.
