1. General information
Please read this guide before installing the energy meter.
If the meter is installed incorrectly, Kamstrup’s guarantee
obligations will no longer apply.
Please note that the following installation conditions must be
obeyed:
- Pressure stage
ULTRAFLOW®:
PN16/PN25/PN40, see marking.
Marking of flow part does not
cover included accessories.
- Pressure stage Kamstrup
sensor set type DS:
PN16
- Pressure stage Kamstrup
stainless steel pockets:
PN25/PN40 - depending on type
If the medium temperature exceeds 90°C we recommend using
flange meters.
Please make sure that MULTICAL® 801 is connected to correct
voltage, either 230 VAC or 24 VAC, see the marking at terminals
27 and 28 at the bottom left.
MULTICAL® 801 must be sealed with seal and wire or a sealing
label after mounting.

2. Mounting of temperature sensors
Temperature sensors used to measure flow and return
temperatures make up a matched pair of sensors and must
never be separated. According to EN 1434 or OIML R75 the
cable length must not be changed.
Replacement of sensors, if required, must always be made in
pairs.
One sensor is marked with a red sign, and must be installed in
the flow pipe.
The other sensor is marked with a blue sign, and must be
installed in the return pipe.
3
2.1 Pocket sensor pair
Preferably, sensor pockets must be mounted in tee-pieces or in
45°C lateral Y-pieces. The tip of the sensor pocket must be
placed pointing towards the flow direction and in the middle of
the water flow.
Temperature sensors should be inserted to the bottom of the
pockets. If a quick response time is required, “non-hardening”
heat conducting paste can be used.
Push the plastic sleeve on the sensor cable into the sensor
pocket and secure the cable with the supplied M4 sealing
screw. Fasten the screw with your fingers only. Seal the pockets
using seal and sealing wire.
4
2.2 Short direct temperature sensor set
The short direct sensor can be mounted in special ball valves or
in special angle tee-pipes, both with threads up to R1 and builtin M10 union for the short direct sensor.
For mounting in existing heating installations with standard
angle tees Kamstrup A/S can also supply R½ and R¾ brass
nipples which fit the short direct sensors.
The short direct sensor can also be fitted directly into all
ULTRAFLOW® variants from Kamstrup A/S with G¾ and G1
thread on the meter case. Fasten the brass unions of the
sensors lightly (approx. 4 Nm) by means of a 12 mm face
wrench, and seal the sensors with seal and wire.

3. Mounting of flow sensor
Before mounting the flow sensor, flush the system thoroughly
and remove protection plugs/plastic membranes from the flow
sensor.
Correct flow sensor position (flow or return pipe) appears from
the front label placed on the MULTICAL® 801. The flow direction
is indicated by an arrow on the side of the flow sensor.
Gasket
Gasket
Tightening approx. 4 Nm
Glands and gaskets must be mounted as shown in the above
drawing.
Straight inlet: ULTRAFLOW® requires neither straight inlet nor
outlet to meet the Measuring Instruments Directive (MID)
2004/22/EEC, OIML R75:2002 and EN 1434:2007. Only in case
of heavy flow disturbances before the meter will a straight inlet
section be necessary. We recommend following the guidelines
in CEN CR 13582.
To prevent cavitation, the operating pressure at the ULTRAFLOW®
must be min. 1.5 bar at qp and min. 2.5 bar at qs (4.5 bar for
DN80). This applies to temperatures up to approx. 80°C.
ULTRAFLOW® must not be exposed to pressures below ambient
pressure (vacuum).

5. Power supply
MULTICAL® 801 can be voltage supplied by means of 24 VAC or
230 VAC.
5.1 Backup battery
MULTICAL® 801 includes a backup battery, which ensures that
all relevant measurements continue during power failure.
The battery ought to be replaced after 10 years’ normal
operation, or after 1 year without mains connection.
The type number of the backup battery is 66-99-619
The voltage of a lithium battery is almost constant throughout
the whole lifetime of the battery (approx. 3.65 V). Therefore, it is
not possible to determine the remaining capacity 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.
6. Operational check
Carry out an operational check when the energy meter has been
fully mounted. Open the thermo-regulators and cocks in order
to establish a water flow through the heating system. Activate
the upper push button on the MULTICAL® 801 and check that the
display values for temperature and water flow are reliable.

7. Electrical connection
4-wire
2-wire
The temperature sensors are mounted in the terminals of the
calculator as shown above. Jumpers are used when mounting
2-wire sensors.
In connection with flow sensors V1 and V2, the belowmentioned colours are used for connection of ULTRAFLOW® and
electronic pick-up units.

MULTICAL® 801
MULTICAL ® 801 functions in the following way:
The flow sensor registrates how many m3 (cubic metres) of
district heating water are circulating through the heating
system.
The temperature sensors, placed in flow and return flow
pipes, register cooling, i.e. the difference between the input
and output temperatures.
MULTICAL ® 801 calculates the consumed amount of energy
based on the district heating water volume and cooling.
Readings in the display
When the upper front key
is activated, a new reading
appears.
The lower front key is used to show historical readings and
average values.
4 minutes after the front key has been activated reading of
consumed energy will automatically appear.
