1 In general
Please read this guide carefully before installing the energy meter.
In case of incorrect mounting, Kamstrup's guarantee obligations no longer apply.
By connecting to 230 V supply, there is a risk of electric shock.
When working on the flow sensor in the installation, there is a risk of outflow of (hot)
water under pressure.
At a media temperature higher than 60 °C, the flow sensor should be shielded from
unintended contact.
Please note that the following installation conditions must be obeyed:
- Pressure stage ULTRAFLOW®: PN16/PN25, see marking
- Pressure stage Kamstrup sensor pair, type DS: PN16/PN25
- Pressure stage Kamstrup pocket sensors, type PL: PN25
At media temperatures above 90 °C, we recommend flange sensors as well as wall-mounting of
MULTICAL®.
At media temperatures below the ambient temperature, MULTICAL® must be wall-mounted, and
the flow sensor/ULTRAFLOW® must be a condensation-proof version.

MULTICAL® 803 & ULTRAFLOW®
2 Mounting of temperature sensors
The temperature sensors used for measuring inlet and outlet temperatures respectively,
constitute a matched sensor pair, which must never be separated. According to EN 1434/OIML R75,
the cable length must not be changed. Should replacement be necessary, both sensors must be
replaced.
The sensor marked with a red sign is to be installed in the inlet pipe. The other sensor, marked with
a blue sign, is to be installed in the outlet pipe. For mounting in the calculator, see the paragraph
”Electrical connection”.
Note: The sensor cables must neither be exposed to jerking nor pulling. Please be aware of this
when binding the cables, and be careful not to pull the binders unnecessarily tight as this
may damage the cables. Please also note that temperature sensors must be mounted from
below in cooling and heat/cooling installations.
2.1 Short direct sensor (DS)
The short, direct sensors up to DN25 can be mounted in special ball valves with built-in M 10
socket for the short direct sensor. They can also be mounted in installations with standard
tee-pieces. Kamstrup A/S can supply R½ and R¾ brass nipples that fit the short direct sensors.
The short direct sensor can also be mounted directly in selected flow sensors from Kamstrup A/S.
Fasten the sensors’ brass unions lightly (approx. 4 Nm) using a 12 mm face wrench, and seal the
sensors with seal and locking wire.

MULTICAL® 803 & ULTRAFLOW®
2.2 Pocket sensor (PL)
The sensor pockets can be mounted in e.g. a welding sleeve or in a 45° lateral Y-piece. The tip
of the sensor pocket must be placed in the middle of the flow. Push the temperature sensors as
deep as possible into the pockets. If a short response time is required, “non-hardening” thermally
conductive paste can be used. Push the plastic sleeve on the sensor cable into the sensor pocket
and secure the cable by means of the enclosed M4 sealing screw. Fasten the screw with your
fingers only. Seal the pockets using seal and locking wire.

3 Mounting of flow sensor
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 appears either from the calculator’s type label or from the
display where indicates the position in inlet, whereas indicates the position in outlet.
The flow direction is symbolised by an arrow on the flow sensor.
3.1 Mounting of couplings and short direct sensor in flow sensor
Flow sensor and any mounted blind plug can be
used in connection with both PN16 and PN25.
The flow sensor is available with either PN16
or PN25 marking as required. Any provided
extensions and glands can be used for both
PN16 and PN25.
In connection with flow sensors with the
nominal dimensions G¾Bx110 mm and
G1Bx110 mm, it must be checked if the thread
run-out is sufficient.
Couplings and gaskets are mounted as shown
in the figure. Make sure to position the gasket
correctly in the recess of the gland as shown in
the details excerpt in the figure. Gasket

90° 90°
The flow sensor can be mounted horizontally, vertically or at an angle.
Max. 45°
The flow sensor should be mounted with the plastic casing placed
on the side (at horizontal mounting).
The flow sensor (65-5-XXHX-XXX) may be turned up to 45°
downwards in relation to the pipe axis as shown above, if required1.
1Flow sensor types 65-5-XXAX-XXX, 65-5-XXCX-XXX and 65-5-XXJX-XXX may also be turned 45°
upwards.
Note: In installations in which the media temperature is below the ambient temperature,
ULTRAFLOW® in a condensation-proof version must be used. At the same time,
ULTRAFLOW® must not be mounted with the plastic casing turned to below 0°. It is
recommended to turn the plastic casing 45° upwards.
3.3 Mounting of ULTRAFLOW® 54 ≥ DN150
See Installation and user guide no. 5512-887.

3.4 Flow sensor position
Kamstrup flow sensors require neither straight inlet nor straight outlet to meet the Measuring
Instruments Directive (MID) 2014/32/EU, OIML R75:2002 and EN 1434:2015. A straight inlet section
will only be necessary in case of heavy flow disturbances before the meter. It is recommended to
follow the guidelines of CEN CR 13582.
A Recommended position.
B Recommended position.
C Unacceptable position due to risk of air
build-up.
D Acceptable position in closed systems.
E Ought not to be placed immediately after
a valve, with the exception of block valves
(ball valve type) which must be fully open
when not used for blocking.
F Ought not to be placed immediately before
or after a pump.
G Ought not to be placed immediately after a
double bend in two planes.

In order to avoid cavitation, the back pressure at the flow sensor (the pressure at the flow sensor
outlet) must be minimum 1.5 bar at qp(nominal flow) and minimum 2.5 bar at qs(maximum flow).
This applies to temperatures up to approx. 80 °C. The flow sensor must not be exposed to pressure
lower than the ambient pressure (vacuum).

3.5 Installations with two ULTRAFLOW® sensors
MULTICAL® can be used in various applications
with two ULTRAFLOW® sensors, including leak
surveillance and open systems. As a main rule,
when two ULTRAFLOW® sensors are installed
with one MULTICAL®, a close electric coupling
between the two pipes ought to be carried out
on which the two flow sensors are mounted. 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.
ULTRAFLOW®
MULTICAL®
ULTRAFLOW®
• Inlet and outlet pipes are closely electrically coupled.
• The parts of the pipe installation that are electrically connected to the flow sensors must both
be subjected to soldering.
In installations where the electric coupling is
not possible or welding1can occur in the pipe
system, the cable from one ULTRAFLOW®
must be led through a Pulse Transmitter to
obtain galvanic separation before the cable is
connected to MULTICAL®.
1Electric welding must always be carried out
with the grounding connection closest to
the welding point. Damage to meters due
to welding is not comprised by the factory
guarantee.
