ULTRAFLOW® is a static flow sensor based on the ultrasonic principle. It is primarily used as a volume flow sensor
for thermal energy meters such as MULTICAL®. ULTRAFLOW® 54 has been designed for use in heating installations
where water is the heat-bearing medium, whereas ULTRAFLOW® 34 has been designed for use in cooling and
heat/cooling 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 longterm 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 10 m or more, a Pulse Transmitter can be supplied as an accessory. If ULTRAFLOW® is used as
pulse generator for other equipment, it must be connected through a Pulse Transmitter. If a different meter factor
is required, ULTRAFLOW® is connected through a Pulse Divider. Pulse Transmitter and Pulse Divider have a built-in
supply for ULTRAFLOW® and a galvanically separated pulse output.

4.6Pulse Divider configuration CCC-DD-E-MMM
Pulse Divider is configured for ULTRAFLOW® meter factor (CCC) as well as the required meter factor (DD) and pulse
duration (E) for the Pulse Divider according to Table 8 and Table 9.
Table 9. Configuration options as to meter factor (DD) and pulse duration (E) for
Pulse Divider when connected to ULTRALFOW® 54 or 34, qp 40…100.
Based on a qp value, a meter factor for the Pulse Divider is chosen in Table 8 or Table 9. The valid possible pulse
durations are listed on the same line as the chosen meter factor.
Example: For ULTRAFLOW® 54 qp 40 m3/h (5 imp/l, CCC=158) a meter factor for the Pulse Divider of 10 l/imp
(DD=34) is required. Based on this meter factor one of the pulse durations, 20 milliseconds (E=4) or 50
milliseconds (E=5) is selected.
For older types of ULTRAFLOW® (e.g. ULTRAFLOW® type 65), where the correlation between qp and meter factor
(CCC) is not ambiguous, the correct configuration is made by using the flow sensor’s meter factor [imp/l].
Default values in Table 8 and Table 9 are meter factor and pulse duration values for ULTRAFLOW® 54 and 34.

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

7.8 Connection of power supply
If ULTRAFLOW® is connected via Pulse Transmitter or Pulse Divider, ULTRAFLOW® is powered by the supply
module/battery in the Pulse Transmitter/Pulse Divider.
7.8.1 Battery supply
Pulse Transmitter/Pulse Divider is fitted with a D-cell lithium battery with connector. The battery plug is connected
to the output module.
Optimal battery lifetime is obtained by keeping the battery temperature below 30 °C, e.g. by wall mounting the
Pulse Transmitter/Pulse Divider.
The voltage of a lithium battery is almost constant throughout the lifetime of the battery (approx. 3.65 V).
Therefore, it is not possible to determine the remaining capacity of the battery by measuring the voltage.
The battery cannot and must not be charged and must not be short-circuited.
The battery supply may only be replaced by a corresponding lithium battery with connector from Kamstrup A/S.
Used batteries must be handed in for approved destruction, e.g. at Kamstrup A/S. (See Kamstrup document 5510408, ”Lithium batteries - Handling and disposal”).
7.8.2 Mains supply modules
The mains supply modules are protection class II and are connected to the output module via a small two-wire
cable with plugs. The modules are powered via a two-wire mains supply cable (without earth connection) through
the cable connector of the Pulse Transmitter/Pulse Divider. Use supply cable with an outer diameter of maximum
10 mm and ensure correct stripping of insulation as well as correct tightening of cable connection (see paragraph
7.8.4).
Max. permitted fuse: 6 A
230 VAC
This PCB module is galvanically separated from the mains supply and is
suitable for direct 230 VAC mains installation. The module includes a
double-chamber safety transformer, which fulfils double-isolation
requirements when the cover is mounted on the Pulse Transmitter/Pulse
Divider. Power consumption is less than 1 VA/1 W.
National regulations for electric installations must be observed. The 230
VAC module can be connected/disconnected by the district heating
station’s personnel, whereas the fixed 230 VAC installation to the main
electrical panel must be carried out by an authorized electrician.
24 VAC
This PCB module is galvanically separated from the 24 VAC mains supply
and is both suitable for industrial installations with joint 24 VAC supply
and individual installations, which are supplied by a separate 230/24
VAC safety transformer in the main electrical panel. The module includes
a double-chamber safety transformer, which fulfils double-isolation
requirements when the cover is mounted on the Pulse Transmitter/Pulse
Divider. Power consumption is less than 1 VA/1 W.

Pulse Transmitter/Pulse Divider is available with mains supply cable H05 VV-F for either 24 V or 230 V (l=1.5 m):
Figure 20. Mains cable (2x0.75 mm²), max. 6 A fuse.
”H05 VV-F” is the designation of a strong PVC mantle, which withstands max. 70 °C. Therefore, the mains cable
must be installed with sufficient distance to hot pipes etc.
7.8.4 Cable connections
Cable dimension in connections for signal cable: 2…6 mm
Cable dimension in connections for mains supply cable: 4.5…10 mm
Tightening torque: Maximum 4 Nm (cable strain relief minimum 40 N according to EN 61558)
Please note: When supplied by battery the unused cable connection must be sealed off as shown in Figure 22,
page 33.
7.8.5 Change of supply unit
The supply unit of Pulse Transmitter/Pulse Divider can be changed from mains supply to battery or visa versa as
the needs of the supply company change. Thus, it can be an advantage to temporarily change mains supplied
Pulse Transmitter/Pulse Divider to battery supplied, e.g. in case of buildings under construction where the mains
supply can be unstable or periodically missing.
Please note that for Pulse Transmitter/Pulse Divider the supply type appears from the label. If the original supply
type is changed, it will no longer be in accordance with the label.

7.11 Calculator with two flow sensors
MULTICAL 602 and 801 can be used in various applications with two flow sensors, e.g. leak surveillance and
open systems. When two ULTRAFLOW are direct connected to one MULTICAL, a close electric coupling between
the two pipes ought to be carried out as a main rule. If the two pipes are installed in a heat exchanger, close to the
flow sensors, however, the heat exchanger will provide the necessary electric coupling.
Electric coupling
Figure 24. Forward and return pipes are closely electrically coupled.
No welded joints occur.
In installations where the electric coupling cannot be carried out, or where welding in the pipe system
can occur, the cable from one ULTRAFLOW must be routed through a Pulse Transmitter with galvanic separation
before the cable enters MULTICAL.
Figure 25.Forward and return pipes are not necessarily closely coupled.
Electric welding *) can occur.
*)
Electric welding must always be carried out with the earth pole closest to the welding point. Damage to meters
due to welding is not comprised by Kamstrup’s factory guarantee.
7.12 Operational check
Carry out an operational check when the complete meter (flow sensor and calculator) has been installed and
connected. Open thermoregulators and cocks to establish water flow through the installation. Activate the top key
of the calculator and check that the displayed values for temperatures and water flow are credible values.

8 Functional description
8.1 Ultrasound combined with piezo ceramics
Flow sensor manufacturers have been working on alternative techniques to replace the mechanical principle.
Research and development at Kamstrup has proved that ultrasonic measuring is the most viable solution.
Combined with microprocessor technology and piezo ceramics, ultrasonic measuring is not only accurate but also
reliable.
8.2 Principles
The thickness of a piezo ceramic element changes when exposed to an electric field (voltage). When the element
is influenced mechanically, a corresponding electric charge is generated. In this way the piezo ceramic element
can function either as a sender or a receiver or both.
Within ultrasonic flow measuring there are two main principles: the transit time method and the Doppler method.
The Doppler method is based on the frequency shifting which is generated when sound is reflected by a moving
particle. This is very similar to the effect you experience when a car drives by. The sound (the frequency) decreases
when the car passes by.
8.3 Transient time method
The transient time method used in ULTRAFLOW® utilizes the fact that it takes an ultrasonic signal emitted in the
opposite direction of the flow longer time to travel from sender to receiver than a signal sent in the same direction
as the flow.
The transient time difference of a flow sensor is very small (nanoseconds). Therefore, the time difference is
measured as a phase difference between the two 1 MHz sound signals to obtain the necessary accuracy.

In order to minimize the influence from variations of the velocity of sound in water, the velocity is measured via a
number of absolute time measurements between the two transducers. These measurements are subsequently, in
the built-in ASIC, converted into the current velocity of sound which is used in connection with flow calculations.

8.5 Measuring sequences
During flow measuring ULTRAFLOW® passes through a number of sequences, which are repeated at fixed intervals.
Deviations only occur when the meter is in test mode and connecting the supply during initialization/start-up.
The difference between the main routines in normal and verification mode is the frequency of the measurements,
on which pulse emission is based.
It may take up to 16 seconds to obtain correct function after a power cut.

8.6 Function
In the meter’s working range from min. cut-off to saturation flow there is a linear connection between the water
volume flowing through and the number of pulses being emitted. An example of the connection between flow and
pulse frequency for ULTRAFLOW® qp 1.5 m³/h is shown below (Diagram 9).

Table 20. Recommended minimum back pressure.
The purpose of recommended back pressure is to avoid measuring errors due to cavitation or air in the water.
It is not necessarily cavitation in the flow sensor itself, but also bubbles from cavitating pumps or regulating
valves mounted before the sensor. It can take some time for these bubbles to dissolve in the water.
In addition, the water may contain air, which is dissolved in the water. The amount of air which can be dissolved in
water depends on the pressure and the temperature. This means that air bubbles can be formed because of a drop
of pressure e.g. due to an absolute speed rise in a contraction or over the meter.
The risk of these factors affecting accuracy is reduced by maintaining a fair pressure in the installation.
In relation to above table, the steam pressure at current temperature must also be considered. Table 20 applies to
temperatures up to approx. 80 °C. Furthermore, it must be considered that the above-mentioned pressure is the
back pressure at the sensor and that the pressure is lower after a contraction than before one (e.g. cones). This
means that the pressure – when measured elsewhere - might be different from the pressure at the sensor.
This can be explained by combining the continuity equation and Bernoulli’s equation. The total energy from the
flow will be identical at any cross section. It can be reduced to: P + ½ρv2 = constant.
When dimensioning the flow sensor, this must be taken into consideration, especially if the sensor is used within
the scope of EN 1434 between qp and qs, and in case of heavy contractions of the pipe.

TECHNICAL DESCRIPTION ULTRAFLOW® 54 and 34
8.10 Pulse emission
Pulses are emitted at intervals of 1 second. The number of pulses to be emitted is calculated every second. Pulses
are emitted in bursts with a pulse duration of 2…5 ms and pauses depending on the current pulse frequency. The
duration of the pauses between the individual bursts is approx. 30 ms.
The transmitted pulse signal is the average determination of a series of flow measurements. This means that
during start-up there will be a transient phenomenon until correct flow signal has been obtained. Furthermore, this
brings about a pulse tail of up to 8 seconds in case of sudden hold.
8.11 Accuracy
ULTRAFLOW® 54 and 34 have been developed as a volume flow sensor for use with energy meters according to
DS/EN 1434. Permitted tolerances in DS/EN 1434 for flow sensors with a dynamic range of 1:100 (qi:qp) are shown
in Diagram 14. The tolerances are defined for classes 2 and 3 with following formulas:
q
Class 2:
Class 3:
DS/EN 1434 defines following dynamic ranges (qi:qp): 1:10, 1:25, 1:50, 1:100 and 1:250.
p
×+02.02
but max. 5 %
q

×+05.03

q
In connection with accuracies the range from qp to qs is defined as max. flow short-term, where tolerances are
adhered to. There are no requirements as to the relationship between qp and qs. See Table 1 for information on qs
for ULTRAFLOW®.
To ensure that the sensors meet the tolerance requirements, DS/EN 1434-5 specifies calibration requirements in
connection with verification of sensors. The requirements for flow sensors are that they have to be tested at
following 3 points:
qi…1.1 x qi, 0.1 x qp..0.11 x qp and 0.9 x qp…qp
During testing the water temperature must be 50 °C ±5 °C for ULTRAFLOW® as a heat meter.
For ULTRAFLOW® as a cooling meter the water temperature must be 15 °C ±5 °C
Further requirements are that the tolerance of the equipment used to perform the test must be less than 1/5 MPE
(Max. Permissible Error) in order for the acceptance limit to be equal to MPE. If the equipment does not meet this
standard, the acceptance limit must be reduced by the tolerance of the equipment.
ULTRAFLOW® will typically do better than half of the permitted tolerance according to DS/EN 1434 class 2.
The current consumption of ULTRAFLOW® is as follows:
Max. average 50 µA
Max. current 7 mA (max. 40 ms)
8.13 Interface connector/serial data
ULTRAFLOW® 54 and 34 is fitted with a four-pole connector under the cover. Thus, it is not possible to access this
connector without breaking the seal. On delivery, the cover will be sealed with a factory seal and in connection
with verified sensors it will be a laboratory seal (legal seal).
The connector is used for:
• Programming sensor, including adjusting the flow curves by means of METERTOOL
• Setting the sensor to test mode
• Reading accumulated water quantity in connection with calibration
• External control of start/stop in connection with calibration
The interface connector is constructed as shown in Figure 30.

TECHNICAL DESCRIPTION ULTRAFLOW® 54 and 34

The electronics are encapsulated in ULTRAFLOW® 34, and, thus, the four-pole connector is not directly available. In
order to gain access to pin 4 an adapter with four-pole connector is used (see Figure 43, page 60). Before clicking
the adapter onto the electronics housing, a hole is drilled in the cover of the electronics housing at the marking
(ø2 mm, max. drilling depth 10 mm). (See Figure 31.) Subsequently the signal cable is connected to the terminals
of the adapter. (See par. 7.6.)

8.14 Test mode
To minimize the time spent on calibration, ULTRAFLOW® 54 and 34 can be switched into test mode. In test mode
(verification mode) the measuring routines only take one fourth of the time they take in normal mode.
ULTRAFLOW® is put into test mode by connecting pin 4 of the internal connector to ground (Figure 30) and
subsequently connect the supply. After approx. 1 second the sensor goes into test mode and the connection
between pin 4 and ground is disconnected.
Test mode is ended by disconnecting the supply to the sensor.
Note: An ULTRAFLOW® in test mode uses approx. 3 times as much power as in normal mode. However, this does
not influence the total battery lifetime of the energy meter.
8.15 Externally controlled start/stop
In connection with calibration by means of serial data, e.g. in connection with NOWA, ULTRAFLOW® 54 and 34 can
be monitored by an external signal when it is in test mode (see paragraph 8.14 Test mode). This is done by
grounding pin 4 of the internal connector when starting the test and removing it when the test has been
completed. The volume of water that has been accumulated during the test can be read serially.
The accumulation is based on the same data as those used for calculating the number of pulses to be emitted.
In addition to accumulating water volume during test, the sensor corrects for the excess quantity measured in
connection with start as well as the quantity lacking in connection with stop. These deviations occur because the
sensor measures flow at regular intervals, as illustrated in Figure 32 below.

8.16 Calibration using serial data and externally controlled start/stop
The routine for calibrating ULTRAFLOW® using serial data is outlined below.
Figure 33
The sensor must be in test mode (see paragraph 8.14 Test mode).
Calibration is started by connecting the 4th pin of the internal plug (see Figure 33), simultaneously with starting the
test. E.g. this might take place at the same time as the master meter is started or at the same time as the diverter
to the weight is being changed. ULTRAFLOW® accumulates the water volume until you disconnect pin 4 and
terminate the test. Subsequently, the volume accumulated during the test can be read with respect to start and
stop. From the test has been completed until the accumulated quantity of water can be read, minimum 2 seconds
must pass (T
Pulse emission stops when pin 4 is disconnected. The read water quantity and the number of emitted pulses may

9.9 Optimization in connection with calibration
To make a rational test of ULTRAFLOW® it must be possible to reproduce test results. This is also very important if
the sensors tested are to be adjusted.
Experience shows that ULTRAFLOW® operates with standard deviations of 0.3…0.4 % at qi and 0.2…0.3 % at qp.
This is standard deviations at 300…500 pulses at qi, 3000…5000 at qp , and flying start/stop.
In connection with optimization of calibration the following aspects should be taken into account:
Pressure: Optimal working pressure is 4…6 bar of static pressure. This minimizes the risk of air and cavitation.
Temperature: Calibration temperature according to DS/EN 1434-5 is 50 °C ± 5 °C for heat meters and 15 °C ± 5 °C
for cooling meters.
Water quality: No requirements.
Installation - mechanical conditions:
To avoid flow disturbances inlet pipes and distance pieces must have the same nominal diameter as the sensors
(see Table 27). There should be minimum 5 x DN between the sensors. With bends etc. there should be a
minimum distance of 10 x DN. If tests are made at low flow through a bypass at right angles to the pipe, it would
be an advantage to mount an absorber of pressure fluctuations due to the angle of the inlet pipe. This can be a
flexible tube on the bypass. In addition, it would be advantageous to fit a flow straightener before the first
distance piece. Flow disturbances such as pulsations, e.g. pump fluctuations must be minimized. In connection
with calibration, a code of practice concerning distance pieces has been made on the basis of years of experience:
To avoid external disturbances and to achieve an electrical interface as that of MULTICAL®, we recommend that
you use a PULSE TESTER. See paragraph 9.10.
