INSTALLATION

2
1. General information
Read this guide before installing the meter.
In case of incorrect mounting Kamstrup’s guarantee obligations no longer
apply.
MULTICAL®61 consists of a flow sensor and a calculator. The flow sensor electronics
are placed in the calculator’s connecting base, whereas the calculator top is a
display unit. The flow sensor is connected with the calculator by means of a 2.5 m
screened cable.
According to OIML R49 MULTICAL®61 can be described a ”complete meter”. In
practice this means that flow sensor and calculator must NOT be separated. If flow
sensor and calculator have been separated and the seals have thus been broken,
the water meter is no longer valid for billing purposes. Furthermore, the factory
guarantee no longer applies.
The accumulated water consumption, to be used for billing purposes, is displayed
in m3(cubic metres).
Various communication modules and power supplies can be added. The utility can
replace communication module and battery.
If greater distance is required (up to 10 m) between flow sensor and display unit, a
PULSE TRANSMITTER (type number 66-99-618) can be used.
See instructions 5512-587 for further information.
Small-size meters, 1.6 and 2.5 m3/h (except for G¾x110) can be fitted with a
strainer (filter)*. The enclosed special polyethylene gaskets must be used.
1.1 Permissible operating conditions / measuring range
Temperature of medium in flow sensor: 0.1°C...50°C
Pressure stage: Threaded meters PN16
Flange meters PN25
Mechanical environment: M1 (MID). Fixed installation with minimum
vibration.
Electromagnetic environment: E1(MID). Housing and light industry.
The meter’s control cable must be
drawn at min. 25 cm distance from other
installations.
Climatic environment: 5°C...55°C.
Must be installed indoors and in
environments with non-condensing
humidity.
MID = Measuring Instrument Directive 2004/22/EC.
* All threaded flow sensors 1.6 to 10 m3/h (with the exception of G¾ x 110) can be
fitted with an antipollution check valve.

2. Installation
In order to prevent cavitation the back pressure in the flow sensor must be
minimum 1.5 bar at Q3and minimum 2.5 bar at Q4(resizes of Q3and Q4, see label
on flow sensor).
The meter must not be exposed to lower pressure than the ambient pressure
(vacuum).
Pressure stages are PN16 for threaded meters and PN25 for flange meters, see
marking. Flow sensor marking does not cover included accessories.
Straight inlets or outlets are not required in order to comply with MID. A straight
inlet section will only be necessary in case of heavy flow disturbances before the
meter.
2.1 Mounting the flow sensor
Prior to the installation of the flow sensor the system ought to be flushed, a fitting
piece replacing the meter.
Remove adhesive wafers/ protection membranes from the meter’s inlet and outlet
and mount the flow sensor with glands.
You must always use new gaskets in original quality.
The flow direction is indicated by an arrow on the side of the flow sensor.
Mounting the sensor you must make sure that the threaded length of the glands
does not prevent proper tightening of the sealing surface and that PN10 glands are
used (PN16 glands/gaskets can be used).
When the installation has been completed, water flow can be turned on. The valve
on the inlet side must be opened first.
Using strainer (filter) or nonreturn valve the enclosed thicker PE gaskets must be
used to avoid damaging strainer or nonreturn valve. (PE = Polyethylene)

2.3 Mounting of calculator
If the electronics are exposed to the risk of condensation, MULTICAL®61 must be
mounted on a wall.
Use the fitting as a template to mark and drill two 6 mm holes in the wall.
Alternatively, an angle fitting is mounted on the flow sensor (type no. 3026-252, is
ordered separately).
The cable must be mounted minimum 25 cm from other electric installations.
Do not forget to seal the calculator.
Important! ULTRAFLOW®24 may be
turned upwards to max. 45°
and downwards to max. 90°
in relation to the pipe axis.
The plastic housing must
not be turned upwards.

3. Power supply
MULTICAL®61 can be powered by means of a built-in lithium battery or 24 VAC or
230 VAC mains supplied via an integral supply module.
The two cables from battery or supply module are mounted in the calculator’s
terminal strip.
The polarity must be correct: red cable to terminal no. 60 (+)
black cable to terminal no. 61 (-)
3.1 Battery supply
MULTICAL®61 is connected to a lithium battery, D-cell. The battery is marked with
installation year, e.g. 2009 as well as production date.
Kamstrup type number: 66-00-200-100.
Optimal battery lifetime is obtained by keeping the battery temperature below 30°C.
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 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, f.inst. at Kamstrup A/S.
3.2 Supply modules
The modules are protection class II and are connected via a two-
wire cable (without earth) through the cable bush of the calculator
placed in the right side of the connecting base.
Use connecting cable with an outer diameter of 5-10 mm and
ensure correct dismantling as well as correct cable relief.
Max. permitted fuse: 6A
National regulations for electric installations must be observed.

4. Testing the function
Carry out a function control when the meter has been fully mounted. Activate the
pushbutton on MULTICAL®61 and check that the displayed values for water flow
etc. are credible values.
5. Plug-in modules
A number of extra functions can be added to MULTICAL®61 by means of plug-in
modules. The individual modules are briefly described below.
5.1 BASE MODULES
5.1.1 Data + pulse input, type 67-00-10
The data terminals are used for connection of e.g. a PC.
The signal is passive and galvanically separated by means
of optocouplers. Conversion into RS232 level requires
connection of data cable 66-99-106 (D-Sub 9F) or
66-99-098 (USB) with the following connections:
62 Brown (DAT)
63 White (REQ)
64 Green (GND)
The pulse inputs can be used for connection of electricity and water meters.
Please note the maximum pulse frequency as well as correct pulse coding (l/imp.
and Wh/imp.), which are selected by means of the FF and GG configurations.
65 - 66 Input A
67 - 68 Input B
5.1.2 M-Bus, type 67-00-20
M-Bus can be mounted in star, ring and bus topology. Up to 250 meters can be
connected depending on the M-Bus Master’s power supply and the total cable
resistance.
Cable resistance <29 ohm
Cable capacity <180 nF
The M-Bus network is connected on terminals 24 and 25.
The polarity is unimportant.
M-Bus is supplied with pulse inputs.

77
5.1.3 Radio + pulse inputs, type 67-00-21/25/26
The radio module is used for wireless communication
via licence-free radio frequency and can be supplied with
internal antenna or with connection for external antenna.
For further information on radio we refer to
Technical description for radio (5512-013).
The pulse inputs of this module are identical with
the previously described pulse inputs.
Note! Type 67-00-21 includes radio and router functions.
The RadioRouter module must be used with mains
supply.
5.1.4 Prog. data logger + RTC + 4…20 mA inputs + pulse inputs (67-00-22)
The module has connection possibility for two pressure
transmitters on terminals 57, 58 and 59 and can be
adjusted for current reading or pressure ranges of 6, 10 or
16 bar.
The module is prepared for remote reading, data from
meter/module being transferred to the system software
via the connected external GSM/GPRS modem on
terminals 62, 63 and 64.
Furthermore, the module has two extra pulse inputs, VA
and VB.
The module must be powered by 24 VAC.
5.1.5 Analog output
Type 67-00-23, see installation instructions 5512-369 (DK-GB-DE).
5.1.6 Lon Works
Type 67-00-24, see installation instructions 5512-396 (DK) or 5512-403 (GB).

8
5.2 TOP MODULES
Type 67-01: RTC, Real Time Clock
The top module consists of real time clock and
battery backup. When the MULTICAL®61 calculator
top is placed in the connection bracket, thereby
being powered, the top module transfers current
date and time to the calculator.
The top module is recommended for applications
where correct date/time in data loggers as well as
time controlled tariff is important.
Real time clock and battery backup are included in
all other top modules.
The connection terminals are not used in this
module.
Type 67-05: RTC + data output + hourly data logger
The module has a galvanically separated data port
which functions with the KMP protocol. The data
output can be used for e.g. connection of external
communication units or other hardwired data
communication which it is not expedient to carry out
via the optical communication on the meter’s front.
62: DATA (brown) – 63:REQ (white) – 64: GND
(green). Use data cable type 66-99-106 with 9-pole
D-sub or type 66-99-098 with USB connector.
Furthermore, the module includes an hourly data
logger.
Only current and accumulated data can be read.
Hourly/daily/monthly/yearly data loggers cannot be
read through the data port of top module 67-05.

99
Type 67-07: RTC + M-Bus
M-Bus can be connected in star, ring and bus
topology. Depending on M-Bus Master and cable
length/cross section up to 250 meters with primary
addressing can be connected, and even more
using secondary addressing.
Cable resistance in network: <29 ohm
Cable capacity in network: <180 nF
The connection polarity of terminals 24-25 is
unimportant.
Unless otherwise stated in the order, the primary
address consists of the last three digits of the
customer number, it can be changed, however, via
the PC program METERTOOL.
Type 67-08: RTC + pulse output for CV + hourly
data logger
This top module has configurable pulse output,
which is suitable for volume pulses for water meters.
The pulse resolution follows the display (fixed in
the CCC-code). E.g. CCC=419 (Q3= 1.6 m3/h): 1
pulse/0.01m3.
The pulse outputs are optoisolated and withstand
30 VDC and 10 mA.
Normally volume (CV) is connected on 18-19, but
other combinations can be selected via the PC
program METERTOOL, which is also used to select
either 32 or 100 ms. pulse duration.
The module also comprises an hourly data logger
including registers as daily logger.
Type 67-0B: RTC + 2 pulse outputs for CV + prog.
data logger
The RTC and pulse output functions of this top
module are identical with the functions described
for top module 67-08.
The top module is prepared for use in a Kamstrup
radio network together with the RadioRouter
base module 67-00-21-000-3xx, read data being
transferred to the system software via the network
unit RF Concentrator.

6. Retrofitting modules
Both top modules and base modules for MULTICAL®61 can be supplied separately
for retrofitting. The modules are configured and ready for installation from the
factory. Some of the modules require individual configuration after installation,
which is possible by means of METERTOOL.

7. Information Codes ”E”
MULTICAL®61 constantly monitors a number of important functions. If there is a
serious error in measuring system or installation, a flashing “info” will appear in
the display until the error has been corrected. The ”Info” field flashes as long as
the error exists no matter which reading you choose. The ”Info” field automatically
disappears when the reason for the error has been removed.
When the first permanent information code appears it is saved in the EEPROM
together with the date and the volume registers at the time the error occurred.
Furthermore, the info code is saved in the hourly logger (if a top module with hourly
logger is mounted), the daily logger, the monthly logger and the yearly logger for
diagnosis purposes.
Info code types
Info Description Response time
0 No irregularities -
1 Supply voltage has been interrupted -
16 Flow meter V1, communication

64 Leak in cold water system 24 hours
2048 Flow meter V1, wrong pulse figure After reset (e.g. cover off and on)
as well as automatically after
max. 24 hours (at 00:00)
4096 Flow meter V1, signal too weak (air)
16384 Flow meter V1, wrong flow direction
If several info codes appear at a time, the sum of the info codes is displayed.
Example: E2064 = E16 + E2048.
7.1 Transport mode
When the meter leaves the factory it is in transport mode, i.e. the info codes are
active in the display only, not in the data logger. This prevents ”infoevent” from
counting during transportation and non-relevant data from appearing in the info
logger. The first time the meter totalizes the volume register after installation, the
info code automatically becomes active.

8. Troubleshooting
MULTICAL®61 has been constructed with a view to quick and simple installation as
well as long and reliable operation at the consumer.
Should you, however, experience an operating problem, the table below can be
used for troubleshooting.
If repair of the meter becomes necessary, we recommend you to replace parts like
battery and communication modules only. Alternatively, the whole meter ought to
be replaced.
