Application
MULTICAL® 403 is a static heat meter, cooling meter or combined heat/cooling meter based on the ultrasonic principle.
The meter is intended for energy measurement in almost
all types of thermal installations where water is used as the
energy-conveying medium.
MULTICAL® 403 consists of a calculator, a flow sensor and
two temperature sensors. MULTICAL® 403 has been developed for measurement of energy consumption in flats,
single-family and multi-family houses, housing associations,
blocks of flats and small industry. The meter is simple to
install, and it has a temperature range of 2 ...180 °C and a
meter programme with nominal flow from qp 0.6 m³/h
to 15 m³/h.
Robust and accurate
Due to its robust design and high quality MULTICAL® 403 is
practically maintenance free, and its simple set-up makes it
easy to configure via the meter's front keys.
MULTICAL® 403 has been optimised compared to earlier
generations. The total dynamic range has been increased
to 1600:1 from saturation to start up and the meter has an
approved dynamic range of 250:1. It is thereby secured that
every conceivable consumption is measured with the same
well-known Kamstrup precision.

The meter can be powered by mains or battery supply as
required. You can choose between a small battery without
transport restrictions or a more powerful battery with 16
years’ lifetime. No matter which solution you choose the
power consumption of MULTICAL® 403 is low.
Functionality
Volume is measured using bidirectional ultrasonic technique
based on the transit time method, proven a long-term stable
and accurate measuring principle.
Accumulated heat energy and/or cooling energy can be
displayed in kWh, MWh or GJ, all in the form of seven or eight
significant digits. The display has been specially designed
with a view to obtaining longevity.
A wide range of parameters are configurable via the front
keys of MULTICAL® 403: Flow sensor position in inlet or outlet,
energy unit, primary M-Bus address, radio on/off, target dates
etc. Configuration can be carried out on site, thus contributing to a reduction of stocks and installation time.
MULTICAL® 403 is available with communication modules for
Wireless M-Bus, M-Bus and RS232. The modules are available with either pulse inputs or pulse outputs. In addition to
reading current values, the programmable data loggers of
MULTICAL® 403 can be read via M-Bus.

MULTICAL® 403
Energy calculation
MULTICAL® 403 calculates energy on the basis of the formula stated in EN 1434-1, which uses
the international temperature scale issued in 1990 ®ITS-90 and the pressure definition of 16
bar. In a simplified form the energy calculation can be expressed as:
Energy = V x ∆Θ x k.
V
is the added volume of water
∆Θ is the measured temperature difference
k
is the heat coefficient of the water
The calculator always calculates energy in [Wh], which are subsequently converted into the
selected measuring unit.
E [Wh] =
E [kWh] =
E [MWh] =
E [GJ] =
V x ∆Θ x k x 1000
E [Wh] / 1,000
E [Wh] / 1,000,000
E [Wh] / 277,800
MULTICAL® 403 operates with a number of different energy registers. All energy types are data
logged and can be displayed according to configuration. Both in the display and during data
reading each energy type is uniquely defined. The energies are calculated as follows:
E1 = V1 x (t1-t2) x k
E3 = V1 x (t2-t1) x k
E8 = V1 x t1
E9 = V1 x t2
A1 = V1 x (t5-t2) x kt2
A2 = V1 x (t2-t5) x kt2

MULTICAL® 403
Calculator functions
Pulse inputs A and B
MULTICAL® 403 has two extra pulse inputs (A and B), which are placed on selected communication modules. The pulse inputs are used for acquisition and remote accumulation of pulses
from e.g. mechanical water meters and electricity meters. The pulse inputs function independently of the meter itself. Therefore, they are not included in any energy calculations. The two
pulse inputs are identically constructed and can be individually set up to receive pulses from
water meters or electricity meters.
Pulse outputs C and D
MULTICAL® 403 has two extra pulse outputs (C and D), which are placed on selected communication modules. The pulse outputs provide output from selected counter registers
determined by the country code. As the meter has two pulse outputs, it is possible to provide
output from two of the following counter registers via pulse outputs C and D respectively:
• E1 (Heat energy)
• E3 (Cooling energy)
• V1 (Volume)
Note: As selected counter registers are configured by the country code, the configuration
cannot be changed after delivery.
Pulse outputs are by default configured for the following registers:

The resolutions of pulse outputs always follow the least significant digit in the display, which
is determined by the CCC-code e.g. at CCC=119: 1 pulse/kWh and 1 pulse/0.01 m³.
Data logger
MULTICAL® 403 has a permanent memory (EEPROM), in which the results from various data
loggers are saved. The data logger is programmable. The required data logger profile is selected via the RR-code of the configuration number. Unless otherwise stated by the customer
the RR-code is set at 10, which is the default data logger profile. This default data logger profile logs the same data logger registers as MULTICAL® 602, but the logging depth is wider (see
table below). Both data logger registers and logging depths are programmable, and individual
logging profiles can be prepared as required by the customer. Please contact Kamstrup for
further details.
The default data logger profile (RR-code = 10) includes the following six data loggers with allocated depths:
Data logging interval
Yearly logger
Monthly logger
Daily logger
Hourly logger
Minute logger 1-60 min.

MULTICAL® 403
Calculator functions
Integration mode
MULTICAL® 403 uses time-based integration, which means that calculations of accumulated
volume and energy are carried out at fixed time intervals. The time interval is configurable via
the L-code and is independent of the water flow. Please be aware that choice of integration
mode in combination with selected power supply defines the meter’s battery lifetime.
The meter has six optional integration modes; three modes, in which the meter's display
remains switched on and three modes, in which the meter’s display is switched off 4 min.
after the latest registered activation of a front key. During periods with the display switched
off a dot flashes (heart beat indication) at intervals of 30 seconds to indicate that the meter is
active.

• Adaptive mode (4-64 s)
Adaptive mode is the meter’s intelligent integration mode, in which the time interval is continuously adjusted. This mode combines the long battery lifetime obtained in Normal mode
with the high measuring and calculation resolution obtained in Fast mode.
Thus, in adaptive mode MULTICAL® 403 measures at high resolution during periods with
changes in the system requiring accurate measurements and saves battery power during
stable periods.
Adaptive mode is recommended for all systems including those with tap water exchanger.
• Normal mode (32 s)
In normal mode the integration interval is set at 32 seconds, which means that the meter
calculates accumulated volume and energy every 32 seconds.
Normal mode is recommended for systems with hot water tank and similar systems.
• Fast mode (4 s)
In fast mode the integration interval is set at 4 seconds, which means that the meter calculates accumulated volume and energy every 4 seconds. Fast mode is recommended for all
systems including those with tap water exchanger.
Tariffs
MULTICAL® 403 has 3 extra tariff registers TA2, TA3 and TA4, which can accumulate heat
energy or cooling energy (EE=20 accumulates volume) parallel with the main register based
on preprogrammed tariff conditions (to be included in the order). Irrespective of the selected
tariff type, the tariff registers are named TA2, TA3 and TA4 in the display.
As the main register is considered the legal billing register, it is accumulated no matter the
selected tariff function. Tariff conditions TL2, TL3 and TL4 are monitored at every integration.
If the tariff conditions are fulfilled, consumed heat energy, cooling energy or volume is accumulated in either TA2, TA3 or TA4 parallel with the main register.

MULTICAL® 403
Calculator functions
Coefficient of performance (CP) of a heat pump
In houses with heat pumps with single output it is expedient to measure both the released
thermal energy and the gained electrical energy, based on which the coefficient of performance (COP or CP) can be calculated. COP is the abbreviation of ”Coefficient Of Performance”.
The calculation is based on simple proportional numbers between calculated thermal energy
(E1) and electrical energy, which is measured via pulse input B (Input B):
CP=
Thermal energy [E1]
Electrical energy [Input B]
Electrical energy (Input B) is always registered in kWh, whereas thermal energy (E1) is either
registered in kWh, MWh or in GJ depending on the selected B-code. No matter which unit you
choose the meter calculates CP correctly. The CP value is displayed with one decimal and is a
value in the interval 0.0…19.9.
CP can also be used for measurement in gas-fired systems, CP being expressed as kWh/Nm³
gas.
Configurable M-Bus modules
In the module bay of MULTICAL® 403 a communication module can be mounted, adapting the
meter to various applications. The M-Bus module is powered through the M-Bus network and
is thus independent of the meter’s internal supply. Two-way communication between M-Bus
and energy meter is carried out via a digital isolator providing galvanic separation between
M-Bus and meter. The module supports both primary, secondary and enhanced secondary
addressing. The module can communicate at communication speeds of 300, 2400, 9600 or
19200 baud and automatically detects the speed used.
The output data package can be configured to include various register combinations by
means of the programs METERTOOL HCW and READy Manager.
The module can be read at intervals of 10 seconds without the battery lifetime being influenced.

Info codes
MULTICAL® 403 constantly monitors a number of important functions. If a serious error occurs
in measuring system or installation, a flashing “INFO” will appear in the display. The ”INFO”
field keeps flashing as long as the error is present no matter which reading you choose. The
”INFO”-field is automatically switched off when the error has been corrected.
In addition to the ”INFO”-field the current info code can be displayed. In MULTICAL® 403 each

** The info code for leakage at pulse input B, must be actively selected.
Note: Info codes are configurable. Therefore, it is not certain that all above-mentioned parameters are available in a given MULTICAL® 403. This depends on the selected country code.
An info logger saves the info code every time the info code is changed. The latest 50 changes
are saved. The 50 changes plus the corresponding date can be read from the display.

By means of the meter’s primary key you can choose from and switch between the meter’s
four display loops. When delivered the meter is in transport state, which means that USER,
TECH and SETUP loops are available. Depending on country code, SETUP loop can be locked in
transport state and is thereby not available on delivery. TEST loop can only be accessed if the
test seal is broken.
The meter’s four display loops are intended for four different usage situations.
• USER loop
The meter’s configurable display loop, which is intended for the user. The readings in
this loop can be adjusted to the user’s requirements via the DDD-code.
• TECH loop
This loop is intended for technicians and is not configurable. In this loop all the meter’s
readings are shown. The loop comprises readings such as serial number, date, time,
config no., software revision, segment test. TECH loop also comprises a number of fixed
module readings as well as a number of module readings, which depend on the module.
• SETUP loop
This loop is intended for the technician too. In this loop the technician can configure the
meter via the front keys. In general (unless otherwise informed by the customer) the
loop is open in transport state. When the first integration has been carried out by the
meter, SETUP loop is locked and it is no longer possible to access SETUP loop unless
