ULTRAFLOW® 54 DN150-250
TECHNICAL DESCRIPTION

General description
ULTRAFLOW® 54 DN150-250 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 DN150-250 has been
designed for use in heating and cooling installations where water is the heat-bearing medium.
ULTRAFLOW® 54 DN150-250 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 DN150-250 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 DN150-250 is available with internal supply, e.g. if the distance between MULTICAL® and
ULTRAFLOW® is 10 meters or more. If ULTRAFLOW® 54 DN150-250 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.

In addition to the basic variants listed above in Table 3, you must select output module (Y), supply module (Z) as
well as pulse figure programming (CC) and pulse duration (E).
The variant with galvanically coupled output module (Y=1) is solely for use together with MULTICAL®.
The variant with galvanically separated output module (Y=2 or 3) is used in the following situations:
1)
More than 10 m cable length between MULTICAL® and ULTRAFLOW® is required.
2)
As flow sensor no. 2 in connection with MULTICAL®. If two flow sensors are used together with
MULTICAL®, one must include a galvanically separated output module (Y=2 or 3). For further details see

Pressure loss
Pressure loss in a flow sensor is stated as max. pressure loss at qp.
According to EN 1434 max. pressure loss must not exceed 0.25 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:
Q = kv × ∆p
where:
Q = volume flow rate [m³/h]
kv = volume flow rate at 1 bar pressure loss
∆p = pressure loss [bar]

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 (Tmed > 90°C) or medium temperature more than 5°C below ambient
temperature (Tmed < Tamb - 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 qp and min. 2.5 bar at qs.
This applies to temperatures up to approx. 80oC.
When the installation has been completed, water flow can be turned on. The valve on the inlet side must be
opened first.

Installation angle 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.
Figure 3
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)

Mounting of ULTRAFLOW® 54 electronics box
At medium temperature below 90°C (Tmed < 90°C) and at medium temperature less than
5°C below ambient temperature (Tmed > Tamb - 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. 170 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).
Figure 6
At medium temperature above 90°C (Tmed > 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 170 mm.
Figure 7
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 temperature more than 5°C below ambient temperature (Tmed < Tamb - 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).
Figure 8
Alternatively, the electronics box can be wall mounted as long as the distance to flow sensor housing and pipe
installation is minimum 170 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.

ULTRAFLOW® 54 DN150-250
TECHNICAL DESCRIPTION
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 170
mm).
Figure 9
7.2.1
Orientation 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 (Tmed < Tamb - 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.

Straight inlet
ULTRAFLOW® 54 requires neither straight inlet nor outlet in order to fulfil the Measuring Instruments Directive
(MID) 2004/22/EC and EN 1434:2007. 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 by taking the below-mentioned installation methods into consideration:
A Recommended flow sensor position
B Recommended flow sensor position
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 in the
system.
E A flow sensor should not be placed
immediately after a valve, except for
block valves (ball valve type),
which must be fully open when not
used for blocking
F A flow sensor must never be placed
on the inlet side of a pump

7.6
Connection of power supply
If ULTRAFLOW® 54 is mounted with a galvanically coupled output module and connected to MULTICAL®, the flow
sensor is supplied by the calculator. Therefore, the flow sensor must not be fitted with a supply of its own.
ULTRAFLOW® 54 may be connected to other calculators via the galvanically separated output module only, and the
flow sensor must, therefore, be fitted with a supply module or battery.
Supply module and battery are connected to the two-pole connector on the output module.
7.6.1
Battery supply
ULTRAFLOW® 54 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
electronics box.
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”).
7.6.2
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 electronics box. Use supply cable with an outer diameter of 4.5-10 mm and ensure
correct stripping of insulation as well as correct tightening of cable connection (see paragraph 7.6.5).
Max. permitted fuse: 6 A
230 VAC
This PCB module is galvanically separated from the mains supply and
is suitable for direct 230 V mains installation. The module includes a
double-chamber safety transformer, which fulfils double-isolation
requirements when the cover is mounted on the electronics box. 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 V installation to the
main electrical panel must be carried out by an authorized electrician.
Diagram 6
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 V safety transformer in the main electrical panel. The module
includes a double-chamber safety transformer, which fulfils doubleisolation requirements when the cover is mounted on the electronics
box. Power consumption is less than 1 VA/1 W.
National regulations for electric installations must be observed. The 24
VAC module can be connected/disconnected by the district heating
station’s personnel, whereas the fixed 230/24 V installation in the
main electrical panel must only be carried out by an authorized electrician.
Note: This module cannot be supplied by 24 VDC (direct current).

230/24 V safety transformer
The 24 VAC module is especially suited for installation together with a
230/24 V safety transformer, e.g. type 66-99-403, which can be
installed in the main electrical panel before the safety relay. When the
transformer is used, the total power consumption of the meter incl.
the 230/24 V transformer will not exceed 1.7 W.

7.6.3
Mains supply cable
ULTRAFLOW® 54 is available with mains supply cable H05 VV-F for either 24 V or 230 V (l=1.5 m):
Figure 13. 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.
7.6.4
Danish regulations for the connection of mains operated meters
Installation of mains connected equipment for registration of consumption (www.sik.dk, SIK electric installation
notification 27/09, February 2009).
The consumption of energy and resources (electricity, heat, gas and water) of the individual consumer is to an
increasing extent registered by electronic meters, and often equipment for remote reading and remote control of
both electronic and non-electronic meters is used.
General regulations for carrying out installations must be observed. However, the following modifications are
permitted:
•
If meter or equipment for remote reading or remote control is double-isolated it is not necessary to run the
protective conductor to the connection point. This also applies if the connection point is a plug socket
provided that it is placed in a canning which is sealable or can be opened with key or tool only.
If meter or equipment used for remote reading and remote control is connected to a safety transformer mounted in
the panel and direct connected to the branch conductor, no on-off-switch or separate overcurrent protection in
either primary or secondary circuit is required, provided that the following conditions are fulfilled:
•
The safety transformer must either be inherently short-circuit-proof or fail-safe
•
The conductor of the primary circuit must either be short-circuit-protected by the overcurrent protection of
the branch conductor or short-circuit safely run.
•
The conductor of the secondary circuit must have a cross section of at least 0.5 mm² and a current value
which exceeds the absolute maximum current deliverable by the transformer
•
It must be possible to separate the secondary circuit, either by separators, or it must appear from the
installation instructions that the secondary circuit can be disconnected at the transformer’s terminals

Cable connections
Cable dimension in connections: 4.5…10 mm.
Tightening torque: 4 Nm
Please note: If ULTRAFLOW® 54 is mounted with a galvanically coupled output module, or if a galvanically
separated output module is used in combination with battery supply the unused cable connection must be sealed
off as shown in Figure 14.
7.6.6
Change of supply unit
The supply unit of ULTRAFLOW® 54 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 temporary change mains supplied meters to battery
supplied meters e.g. in case of buildings under construction where the mains supply can be unstable or
periodically missing.
Please note that the supply type of some ULTRAFLOW® sensors appears from the label. If the original supply type
is changed, it will no longer be in accordance with the label.

Calculator with two flow sensors
MULTICAL 602/801 can be used in various applications with two flow sensors, e.g. leak surveillance or 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.
• 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,
one ULTRAFLOW must be mounted with a galvanically separated output module and also a supply of its own.
• 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.
7.9
Testing the function
Carry out an operational check when the complete meter (flow sensor and calculator) has been installed and
connected. Open thermo regulators 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.

Functional description
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 proven 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 sender or 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 change which occurs 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 transit time method used in ULTRAFLOW® utilizes the fact that it takes an ultrasonic signal emitted in the
opposite direction of the flow longer 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 in order to obtain the necessary accuracy.

TECHNICAL DESCRIPTION
In principle, the flow is determined by measuring the flow velocity and multiplying it by the area of the measuring
pipe:
Q=F×A
where:
Q is the flow
F is the flow velocity
A Is the area of the measuring pipe
The area and the length, which the signal travels in the sensor, are well-known factors. The length which the signal
travels can be expressed by L = T × V , which can also be written as:
T=
L
V
where:
L is the measuring distance
V is the sound propagation velocity
T is the time
The time can be expressed as the difference between the signal sent with the flow and the signal sent against the
flow.

In connection with ultrasonic flow sensors the velocities

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
converted in the built-in ASIC into the current velocity of sound which is used in connection with flow calculations.

Measuring sequences
During a flow measurement ULTRAFLOW® runs through a number of sequences, which are repeated at fixed
intervals. Deviations only occur when the meter is in test mode and when the supply is connected during
initialization/start-up.
The difference between the main routines in normal mode and fast/test 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-down.

In the meter’s working range from min. cut off to saturation flow there is linear connection between the flow rate
and the number of pulses being emitted. The below diagram shows an example of the connection between flow

According to DS/EN 1434 the upper flow limit qs is the highest flow at which the flow sensor may operate for short
periods of time (<1h/day, <200 h/year), without exceeding max. permissible error. ULTRAFLOW® has no functional
limitations as to the duration of the period, during which the sensor operates above qp.
Please note, however, that high flow velocities may cause cavitation, especially at low static pressure.

Table 12
The purpose of recommended back pressure is to avoid measuring errors as a result of cavitation or air in the
water.
It is not necessarily cavitation in the sensor itself, but also bubbles from cavitating pumps and regulating valves
mounted before the sensor. It can take some time until such bubbles have been dissolved in the water.
Furthermore, water can include air dissolved in the water. The amount of air which can be dissolved in water
depends on pressure and temperature. This means that air bubbles can be formed due to falling pressure, e.g.
caused by a velocity rise in a contraction or above the sensor.
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 12 Applies to
temperatures up to approx. 80° C. Furthermore, it must be considered that the above-mentioned pressure is the
pressure at the sensor, and that the pressure is lower after a contraction than before one (among other things
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 the same at any cross section. It can be reduced to: P + ½ρv2 = constant.

ULTRAFLOW® 54 DN150-250
TECHNICAL DESCRIPTION
8.9
Pulse emission
Pulses are emitted at intervals of 1 sec. 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 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 there
will be a transient phenomenon until correct flow signal has been obtained during start-up. Furthermore, this
brings about a pulse tail of up to 8 sec. in case of sudden hold.
8.10 Accuracy
ULTRAFLOW® 54 has been developed as a volume flow rate sensor for energy meters according to DS/EN 1434.
The permitted tolerances of DS/EN 1434 for flow sensors with a dynamic range of 1:100 (qi:qp) are shown in the
diagram below (Diagram 14). The tolerances are defined for class 2 and class 3 with following formulas:
Class 2:
Class 3:
2 + 0.02 ×
3 + 0.05 ×
qp
but max. 5%
q
qp
but max. 5%
q
DS/EN 1434 defines following dynamic ranges (qi:qp): 1:10, 1:25, 1:50, 1:100 and 1:250.
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 relation between qp and qs. See Table 1 for information on qs for
ULTRAFLOW®.
To render probable that the sensors meet the tolerance requirements, DS/EN 1434-5 specifies calibration
requirements in connection with verification of sensors. It is required that flow sensors are 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 test the water temperature must be 50°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) to permit the acceptance limit to be equal to MPE. If the equipment does not observe 1/5
MPE, the acceptance limit must be reduced by the tolerance of the equipment.
ULTRAFLOW® 54 will typically do better than half of the permitted tolerance according to DS/EN 1434 cl. 2.

8.12 Interface plug/serial data
ULTRAFLOW® 54 is fitted with a four-pole connector under the cover. The cover is supplied with a factory seal, and
in connection with verified sensors it will be a laboratory seal (legal seal). Thus, it is not possible to access the
connector without breaking the seal.
The connector is used for:
•
Meter programming, including adjustment of correction curve by means of METERTOOL
•
Bringing the sensor into 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 20.

8.13 Test mode
To minimize the time spent on calibration, ULTRAFLOW® 54 can be switched into test mode. When ULTRAFLOW® 54
is in test mode (verification mode), the measuring routines only take one fourth of the time they take in normal
mode.
ULTRAFLOW® 54 is put into test mode by connecting pin 4 of the internal connector to frame (Figure 20) and subsequently connect the supply. After approx. 1 sec. the sensor goes into test mode and the connection between pin
4 and frame is disconnected.
Test mode is ended by disconnecting the supply to the sensor.
Please note: An ULTRAFLOW® 54 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.
8.14 Externally controlled start/stop
In connection with calibration by means of serial data, e.g. in connection with NOWA, ULTRAFLOW® 54 can in
verification mode (see paragraph 8.13) be monitored by an external signal. 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 the test, the sensor corrects for the excess quantity in connection
with start, as well as the quantity lacking in connection with stop. These deviations are due to the fact that the
sensor measures flow at fixed intervals as illustrated by Figure 21 below.
Figure 21
5512-876 GB/04-2012/Rev. F1

ULTRAFLOW® 54 DN150-250
TECHNICAL DESCRIPTION
The excess quantity of water in connection with start is the water volume that passes through the sensor during
the time tb1 before the first accumulation V1 within the test period. In the same way the lacking quantity is the
water volume passing through the sensor during the time
t e1 from the last accumulation Vn until stop.
The volume accumulated during the test can be stated as:
V 1 × tb 2
Vn × te1
+ V 2... + Vn +
te1 + te 2
b1 + tb 2

8.15 Calibration procedure using serial data and externally controlled start/stop
The routine for calibrating ULTRAFLOW® 54 using serial data is outlined below.
Figure 22
The sensor must be in test mode (see paragraph 8.13). Calibration is started by grounding pin 4 of the internal
connector (see Figure 22) and at the same time starting the test. This might e.g. take place at the same time as the
master meter is started or the diverter of the weight is changed. Now ULTRAFLOW® accumulates water volume until
pin 4 is disconnected to terminate the test. Subsequently, the volume accumulated during the test can be read in
consideration of start and stop. From the test has been completed and until the accumulated quantity of water can
be read, min. 2 sec. must pass (Tread). Communication with ULTRAFLOW® during test is not allowed.
Pulse emission stops when pin 4 is disconnected. The read water quantity and the number of emitted pulses may
differ as the pulse emission is monitored in intervals of 1 second.

9.3
Optimization in connection with calibration
To make a rational test of ULTRAFLOW® it is important that results obtained in connection with tests can be
reproduced. This is also very important if the tested sensors are to be adjusted.
Experience has shown that ULTRAFLOW® operates with standard deviations of 0.3…0.4% at qi and 0.2…0.3% at qp.
This is standard deviations for 300…500 pulses at qi, 3000…5000 at qp , and flying start/stop.
In connection with optimization of calibration the following sub-components can be considered:
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.
Water quality: No requirements
Installation - mechanical conditions:
To avoid flow disturbances the inlet pipes and distance pieces must have the same nominal diameter as the
sensors. There should be min. 5 x DN between the sensors. In connection with calibration, a code of practice for
distance pieces has been made on the basis of many years' experience:
The lengths of the distance pieces must be 10 x DN.
With bends etc. there should be a min. distance of 10 x DN. If tests are made at low flow with a bypass at right
angles to the pipe, it will be an advantage to mount an absorber of pressure fluctuations due to the perpendicular
inlet. This can be a flexible tube on the bypass. In addition, it will be an advantage to mount a flow straightener
before the first distance piece. Flow disturbances such as pulsations, e.g. pump fluctuations must be minimized.
Installation - electrical conditions:
To avoid external disturbances and achieve an electrical interface like MULTICAL® we recommend the use of a
PULSE TESTER.
