MULTICAL® 61 Cold Water Meter

English

INSTALLATION

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the water meter is no longer valid for billing purposes.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

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)

FLOW

ULTRAFLOW®24 can be mounted

vertically, horizontally or at an angle.

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.

For direct mains connection.

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.

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).

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.
