1General Descr pt on
ULTRAFLOW
®
54 is a static flow sensor based on the ultrasonic principle. It is primarily used as a volume flow
sensor for heat meters such as MULTICAL
®
. ULTRAFLOW
®
has been designed for use in heating installations where
water is the heat-bearing medium.
ULTRAFLOW
®
employs ultrasonic measuring techniques and microprocessor technology. All calculating and
measuring circuits are collected on one single board, providing a compact and rational design in addition to
exceptionally high measuring accuracy and reliability.
The flow is measured using bidirectional ultrasonic technique based on the transit time method, proven a long-
term stable and accurate measuring principle. Two ultrasonic transducers are used to send the sound signal 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 pulse cable is used to connect ULTRAFLOW
®
to the 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.
Where ULTRAFLOW
®
is to be used as a flow sensor with built-in supply, e.g. if the distance between MULTICAL
®
and ULTRAFLOW
®
is 1 m or more, a Pulse Transmitter can be supplied as an accessory. If ULTRAFLOW
®
54 is used
as pulse generator for other equipment, it must be connected through a Pulse Transmitter. The Pulse Transmitter
has a built-in supply for ULTRAFLOW
®
and a galvanically separated pulse output.

6Pressure loss
The pressure loss in a flow sensor is stated as the max. pressure loss at q
p
. According to EN 1434 the 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 sensor 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]

7Installat on
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 the drawings overleaf.
Pressure stage of ULTRAFLOW
®
54: PN16/PN25, see marking. Flow sensor marking does not cover included
accessories.
Temperature of medium, ULTRAFLOW
®
54: 15…13 °C/15…9 °C, see marking.
Mechanical environment: M1 (fixed installation with minimum vibration).
Electromagnetic environment: E1 and E2 (housing/light industry). The meter’s control 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).
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. Battery for replacement: Kamstrup type 66- -2 -1 . Other repairs require subsequent reverification
in an accredited laboratory.
ULTRAFLOW
®
can only be connected direct to Kamstrup’s calculators on terminals 11-9-1 , as shown in aragra h
7.6. Connection to other types of calculators requires the use of a Pulse Transmitter.
Note: Please make sure that “pulse/litres” is identical on flow meter and calculator
At medium temperatures above 9 °C use of flange meters is recommended. Additionally, MULTICAL
®
calculator or
Pulse Transmitter should be wall-mounted.
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 °C.
ULTRAFLOW
®
must not be exposed to pressure lower than the ambient pressure (vacuum).
When the installation has been completed, water flow can be turned on. The valve on the inlet side must be
opened first.

54 may be installed horizontally,
vertically, or at an angle.
Important!
For ULTRAFLOW

54 the electronics/plastic
case must be placed on the side (when
installed horizontally).
ULTRAFLOW
®
54 may be turned up to ±45° in
relation to the pipe axis.

7.2 Stra ght nlet
ULTRAFLOW
®
54 requires neither straight inlet nor straight outlet to meet the Measuring Instruments Directive
(MID) 2 4/22/ EC, OIML R75:2 2 and EN 1434:2 7. A straight inlet section will only be necessary in case of
heavy flow disturbances before the meter. We recommend following the guidelines of CEN CR 13582.
Optimal position can be obtained if you take the below-mentioned installation methods into consideration:
Figure 6
For general information concerning installation see CEN report DS/CEN/CR 13582, Heat meter Installation.
Instructions in selection, installation and use of heat meters.
7.3 Operat ng pressure
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 °C. ULTRAFLOW
®
must not be exposed to pressure lower than the
ambient pressure (vacuum). For further information on operating pressure, see aragra h 8.7 Guidelines for
dimensioning ULTRAFLOW
®
A Recommended position of flow meter
B Recommended position of flow meter
C Unacceptable position due to risk of air
build-up
D Acceptable in closed systems.
Unacceptable position in open systems
due to risk of air build-up.
E A flow meter ought not to be placed
immediately after a valve, except from
closing valves (ball check valve type),
which must be completely open when not
used for closing
F Never place a flow meter on the inlet side
of a pump
G A flow meter ought not to be placed after a
double bend, in two levels
