1General Descri tion
MULTICAL
®
61 is a cold water meter ( ,1…5 °C) and hot water meter ( ,1°C…9 °C) and consists of the flow sensor
ULTRAFLOW
®
24 and the calculator MULTICAL
®
6 1.
MULTICAL
®
61 is a static water meter based on the ultrasonic principle. The water meter has been developed on
the basis of our experience since 1991 with the development and production of static ultrasonic meters.
The meter, which has been designed to measure the water consumption in ”utility room environments”, has been
subjected to a very comprehensive OIML R 49 type test in order to secure a long-term stable, accurate and reliable
meter. One of the water meter’s many advantages is the fact that it has no wearing parts, which entails longevity.
Furthermore, the starting flow of the meter is only 3 l/h, providing accurate measurement also at low flows.
According to OIML R49 MULTICAL
®
61 can be described a ”complete water meter”. In practice this means that flow
sensor and calculator must not be separated.
MULTICAL
®
61 employs ultrasonic measuring techniques and microprocessor technology. All circuits for
calculation of flow measurements are placed in the calculator base. The flow sensor is without electronics in order
to protect it against condensation water. The flow sensor is connected with the calculator base by means of a 2.5
m screened cable.
If flow sensor and calculator have been separated and the seals have therefore been broken, the meter is no
longer valid for billing purposes. Furthermore, the factory guarantee no longer applies.
The volume is measured using bidirectional ultrasonic technique based on the transit time method, proven a long-
term stable and accurate measuring principle. Two ultrasonic transducers are used to send sound signals both
against and with the flow. The ultrasonic signal travelling with the flow reaches the opposite transducer first. The
time difference between the two signals can be converted into flow velocity and thereby also volume.
The accumulated water consumption is displayed by MULTICAL
®
61 in m
3
with seven significant digits and the
measuring unit. The display has been specially designed to obtain long lifetime and sharp contrast in a wide
temperature range.
Other reading options are operating hour counter and current flow, max. and min. flow, information code,
customer number and segment test etc. – depending on configuration.
All registers are saved daily in an EEPROM for 46 days. Furthermore, monthly data for the latest three years and
yearly data for the latest 15 years are saved.
The water meter is powered by an internal lithium battery with up to 12 years’ lifetime. Alternatively the meter can
be mains supplied, either by 24 VAC or 23 VAC.
MULTICAL
®
61 can be fitted with plug-in modules in both calculator top (top modules) and in connecting base
(base modules). Thus, the meter can be adapted to many different applications and data readings.
In addition to the water meter’s own data, MULTICAL
®
61 has two extra pulse inputs, VA and VB, for collection and
remote accumulation of pulses from e.g. water and electricity meters. The pulse inputs are included in the base
modules. Pulse inputs VA and VB function independently of the other inputs/outputs.
MULTICAL
®
61 is available with communication modules for e.g. radio, M-Bus, LON, /4..2 mA and RS232.
MULTICAL
®
61 includes data communication ports. An optical eye on the front of the calculator top makes it
possible to read consumption data and data logger as well as to establish a serial PC connection for configuration
of the water meter. Via plug-in modules it is possible to connect to external communication devices. MULTICAL
®
61 can be delivered with communication modules for e.g. radio, M-Bus, LON, /4...2 mA and RS232.

MULTICAL
®
61 can be ordered in countless combinations as required by the customer. First select the required
hardware from the type overview. Then select ”Prog”, ”Config” and ”Data” to suit the application in question.
The “Prog” and “Config” codes are printed on the front label and can be read out via the display or via
METERTOOL. It is only possible to read out “Data” via METERTOOL.
The supplied meter is configured from the factory and ready for use, but can also be changed/reconfigured after
installation. However, this does not apply to type number and CCC-code which cannot be changed unless the
verification seal is broken. This requires that changes must be made by an accredited meter laboratory.
4.1 PROG (A-B-CCC-CCC)
The meter’s legal parameters are determined by the “Prog”, which cannot be changed without breaking the
verification seal. This means that the change must be made by an accredited meter laboratory.

The CCC-code states the calculator’s adaption to a specific flow sensor type to the effect that calculating speed

to minimum resolution and maximum register overflow are obeyed.
The ”Internal value CCC-code” must be identical with the selected CCC-code.

DDD = 714 is the ”standard code” for hot water meter type 67-Z-xxxx 17xx, whereas DDD = 814 is the ”standard
code” for cold water meter type 67-Z-xxxx 18xx. Contact Kamstrup for other combinations.
A data reading can include up to 36 pieces of monthly data and up to 15 pieces of yearly data; the number is
determined by the DDD-code.

4.2.4 >MN< Configuration of leak limits
When MULTICAL
®
61 is used for leak surveillance, the sensitivity is determined by the configuration of ”MN”. See
paragraph 8.6
Leak surveillance (V1)
M= N=
Leakage sensitivity
(at . 1 m

resolution in display)
OFF OFF
1 2 l/h (3 min. without counting in display)
2 10 l/h (1 hour without counting in dis lay)
3 5 l/h (2 hours without counting in display)
Note: M= and N=2 are default values when leak surveillance is used. Increased sensitivity, e.g. N=3, can only be
achieved by means of METERTOOL.
Info codes for leakage (info code 64) are only active when M = and N > respectively.
NB: Input VA of MULTICAL
®
61 cannot be used for leak surveillance.

6Pressure Loss
According to OIML R 49 the maximum pressure loss must not exceed .63 bar in range Q
1
up to and incl. Q
3
and
max. 1. bar at Q
4
respectively. The pressure loss is without anti-pollution check valve.
The pressure loss in a sensor increases with the square of the flow and can be stated as:
pkvQ ∆×=
where:
Q = volume flow rate [m³/h]
kv = volume flow rate at 1 bar pressure loss [m³/h]
∆p = pressure loss [bar]
