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.

6 Kamstrup A/S • 55122412_A1_GB_2019-03
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

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).

MULTICAL® 803 & ULTRAFLOW®
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.

4 Mounting the calculator
The MULTICAL® calculator can be mounted either directly on the wall (wall-mounting) or on
ULTRAFLOW® by use of bracket 3026-857 (compact mounting).
4.1 Wall-mounting
It is recommended to wall mount MULTICAL® 803 directly on an even wall. Wall-mounting requires
the use of three screws with corresponding rawlplugs. MULTICAL® 803 is mounted on the wall by
first mounting the upper screw in the wall and screw this almost all the way in. Then, hang the
calculator on this screw. With the calculator mounted on the upper screw, the positions of the
lower two screw eyes are marked on the wall after which screws for these can be mounted.
4.2 Compact mounting
In some cases, compact mounting of the MULTICAL® 803 calculator may be an advantage.
The MULTICAL® 803 calculator is large and only suitable for compact mounting in places where
the installation can be secured against mechanical influences such as impacts. By compact
mounting, the calculator is mounted on ULTRAFLOW® using mounting bracket 3026-857 If
there is a risk of condensation (e.g. in cooling applications), the calculator ought to always be
wall-mounted. Furthermore, ULTRAFLOW® in cooling applications must be the condensation-proof
version.
Note: In case of compact mounting, it may be necessary to use the enclosed angle fitting with
some types of ULTRAFLOW® to obtain a required combination of viewing angle for the
calculator's display and installation angle for ULTRAFLOW®.

5 Electrical connection
5.1 Connection of temperature sensors
Temperature sensors are connected to MULTICAL® 803 via the screw terminals on the connection
PCB. It is possible to use both 4-wire and 2-wire sensor types. When using 2-wire sensors, it is
important to mount the supplied jumper on the pins marked with 2-W, located directly above the
screw terminals on the connection PCB. If the supplied jumper is lost, it is possible to terminate
the extra connection terminals by short-circuiting them in pairs as illustrated in red in the table
below.

6 Connection of power supply
6.1 Mains supply
MULTICAL® 803 is available with supply modules for either 24 VAC/VDC or 230 VAC.
MULTICAL® 803 can be supplied from either 24 VAC/VDC or 230 VAC with cable through the large
cable connection to the left in the connection base. Use connecting cable with an outer diameter
of 4-10 mm and ensure correct cable stripping as well as correct mounting of cable relief. If
connecting to 230 VAC, it is important to make sure that the whole installation complies with
current regulations. Kamstrup A/S can provide a supply cable to connect the mains supply, in the
size 2 x 0.75 mm². The supply cable to the meter must never be protected by a larger fuse than
permitted for any given cable size.
In case of doubt, it is recommended to take advice from an authorised electrician and get an
individual assessment of the execution of the installation in question. In addition, note that work
on fixed installations and any intervention in the fuse box must be carried out by an authorized
electrician only.
For installation in Denmark: See “Installation of mains connected equipment for registration of
consumption” from the Danish National Safety Board.
Replacement and extension of the mains supply
PLEASE MAKE SURE TO DISCONNECT THE MAINS SUPPLY FROM THE CONNECTION PCB
BEFORE INITIATING THE REPLACEMENT OR EXTENSION OF THE SUPPLY!
The mains supply in MULTICAL® 803 consists of up to three supply modules of protection class
II, which are connected to the underside of the connection PCB in the meter via a two-wire cable
with connector at one end and screw terminals at the other. It is possible to connect 2 x 3.6 V
supply modules to calculator and module slots as well as a 24 VDC supply module to the supply
of analog outputs or passive third-party flow sensors. Read more in the technical description of
MULTICAL® 803, document no. 5512-2360.
Note: Replacement and extension of the mains supply should always be carried out at a
workshop.

15Kamstrup A/S • 55122412_A1_GB_2019-03
MULTICAL® 803 & ULTRAFLOW®
6.2 Backup battery
MULTICAL® 803 comes with backup of calculator, temperature sensors and flow sensors so that
the basic meter function is maintained in the event of an interruption of the mains supply. It is,
however, possible to extend the backup functionality to include the communication module in
module slot 1. This is done by moving the connection of the backup battery to the connector under
the label with the text MODULE 1 placed in the calculator top.
Note: Not all communication modules are suitable for backup operation. For example,
communication modules with pulse outputs and LON communications cannot be used with the
appropriate battery life. Read more about appropriate modules in the technical description of
MULTICAL® 803, document no. 5512 -2360.
Optimal battery lifetime is obtained by keeping the battery temperature below 30 °C, e.g. by
wall mounting. The voltage of a lithium battery is almost constant throughout the lifetime of the
battery (approx. 3.65 VDC). 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. Used batteries must be handed in for approved destruction, e.g. at Kamstrup A/S.
Further details appear from the document on handling and disposal of lithium batteries
(5510-408).
7 Testing of function
Carry out an operational check when the energy meter has been fully mounted. Open
thermoregulators and valves to enable water flow through the heating system. Activate the front
key of MULTICAL® to change display reading, and check that the displayed values for temperatures
and water flow are credible values.

MULTICAL® 803 & ULTRAFLOW®
8 Info code
MULTICAL® constantly monitors a number of important functions. If a serious error occurs in the
measuring system or installation, a flashing “INFO” appears in the display. The “INFO” field keeps
flashing as long as the error is present, no matter which reading you choose. The “INFO” field
automatically switches off when the error has been corrected. For indicating current errors in
MULTICAL®, it is possible to scroll to the information code in the display. This is the display in which
”INFO” does not flash, but is shown permanently. The information code display is available both in
the USER loop and TECH loop. The info code consists of 8 digits, and each functionality has its own
digit dedicated to the indication of relevant information. For example, all information concerning
temperature sensor t1 is shown in the display as the second digit from the left.
