TECHNICAL DESCRIPTION MULTICAL® 62
1 General Description
MULTICAL® 62 is a cold water meter (0,1…50C) and hot water meter (0,1C…90C) and consists of the flow
sensor ULTRAFLOW
®
24 and the calculator MULTICAL® 602.

MULTICAL
62 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
62 can be described as a ”complete water meter”. In practice this means that
flow sensor and calculator must not be separated.
®
MULTICAL
62 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If flow sensor and calculator have been separated and the seals have therefore been broken, the meter is no
longer valid for billing purposes.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, a proven
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
62 in m3 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 460 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 13 years’ lifetime. See paragraph 10.2.
Battery lifetimes. Alternatively the meter can be mains supplied, either by 24 VAC or 230 VAC.
®
MULTICAL
62 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
62 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
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
62 is available with communication modules for e.g. radio, M-Bus, LON, 0/4..20 mA and RS232.
®
62 includes data communication ports. An optical eye on the front of the calculator top makes it

62 can be delivered with communication modules for e.g. radio, M-Bus, LON, 0/4...20 mA and RS232.
This technical description is prepared to give utility managers, meter electricians, consulting engineers and
distributors the possibility of utilizing all functions available in the MULTICAL
®
62. Furthermore, the description is
made for laboratories for the testing and verification process.

MULTICAL® 62 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 “prog"(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.

TECHNICAL DESCRIPTION MULTICAL® 62
DDD = 714 is the ”standard code” for hot water meter type 62-Z-xxxx0017xx, whereas DDD = 814 is the ”standard
code” for cold water meter type 62-Z-xxxx0018xx. 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.
See paragraph 8.3.2 for more info on display structure.
Display example showing
the PROG number.
A complete survey of existing display codes (DDD) appears from a separate document.
Please contact Kamstrup for further details.
4.3 Real Time Clock (RTC)
MULTICAL 62 has built-in real time clock and battery backup. This is valuable for applications where correct
date/time in data loggers as well as time-controlled tariffs are important. The battery will ensure the RTC function
for at least 3 years without power during the entire lifetime of MULTICAL
the RTC, meaning that the display will go blank, when the main supply or main battery is off.
®
62. This small battery will only back-up
If a top module with RTC is mounted, the top module’s RTC will not have any effect on the meter’s own RTC.
