Compact design
MULTICAL® 402 is the compact
meter with minimum installa-
tion requirements that offers
you maximum functionality at a
competitive price. You can
easily read both current, accu-
mulated and target values
direct from the display or via
hand-held terminal. All log
values can be read and ana-
lysed via the PC program
LogView. Pulse outputs for
energy and volume guarantee
simple connection to building
automation. Alternatively, you
can choose two pulse inputs for
connection of water meter.
Extended longevity
MULTICAL® 402 is maintenance-
free and the integral flow
sensor ASIC guarantees you the
most accurate compact meter
on the market. The 16-year
D-cell battery is a supply source
that will last as long as the
meter. Alternatively, you can
choose a 6-year 2xAA-cell
battery to be replaced when the
meter needs reverification.
Thus, the consumers obtain the
most accurate consumption
billing and the operating costs
are reduced.
Wireless freedom
Remote reading of the compact
meter MULTICAL® 402 means
wireless freedom to quickly
obtain optimal data safety and
top flexibility. MULTICAL® 402
and Wireless M-Bus provide
you with a Plug and Play instal-
lation – easy to mount. Wire-
less M-Bus is one-way radio
communication with open
protocol. MULTICAL® 402 with
Wireless M-Bus is read by a
Wireless M-Bus Reader. You can
also read the meter by means
of a USB Meter Reader, a
hand-held terminal or AMR.
MULTICAL® 402
– compact on the outside, multifunctional on the inside
The compact meter MULTICAL® 402
MULTICAL® 402 is a compact meter which consists of a calcu-
lator, a flow sensor based on ultrasound and two temperature
sensors. According to EN1434 this means in practice that
flow sensor and calculator of a compact meter must not be
separated. If flow sensor and calculator have been separated
and the seals have, thus, been broken, the meter needs
reverification.
MULTICAL® 402 calculator
Kamstrup's calculators are based on state of the art heat
technology. The advanced calculator is used together with
the widest flow sensor range on the market, and even at
minimum temperature differences the measuring accuracy is
unequalled.
Ultrasonically based flow sensor
More than 20 years' experience has proved that the ultra-
sonic principle is most reliable in the long run. The volume is
measured using bidirectinal ultrasonic technique according
to the transit time method. Simultaneously, two ultrasonic
transducers send sound signals with and against the flow
direction respectively.
The flow sensor range for MULTICAL® 402 comprises meters
between qp 0,6 m³/h and qp 15 m³/h. MULTICAL® 402 is
used for heat, cooling and combined heat and cooling meas-
urement in all water-based systems with temperatures from
2°C to 130°C. The meter registers the heat consumption in
all water-based heating installations with temperatures from
15°C to 130°C and in combined heat and cooling installa-
tions from 2°C to 130°C.
The unique temperature measuring circuit and the accurately
matched Pt500 temperature sensors guarantee reliable
measuring results. The long-term stability and accuracy of
the flow sensor are not influenced by the flow velocity. Even
if the nominal velocity is doubled, the long-term stability and
accuracy of the flow sensor are unchanged.
Accuracy class 2 or 3, wide dynamic range (qp/qi 100:1),
and the high permanent overload capability (qs/qp 2:1) are
standard features.

Wireless M-Bus Pulse outputs CE/CV
Pulse inputs VA/VB
Autoconfiguration Data loggers
Wireless M-Bus has been de-
signed and optimised to read
the battery supplied
MULTICAL® 402 and obtain
16 years' battery lifetime.
Wireless M-Bus is one-way
radio communication with
open protocol. The commu-
nication between meter and
module is based on the KMP
(Kamstrup Meter Protocol),
which is also an open pro-
tocol. MULTICAL® 402 with
Wireless M-Bus is read by
a Wireless M-Bus Reader.
Subsequently, data is auto-
matically transferred to the
corresponding AMR software
and exported to a billing
program.
MULTICAL® 402 can be
equipped with pulse outputs
for energy (CE) and volume
(CV) respectively, for remote
accumulation in e.g. a BMS
system. Instead of two pulse
outputs the compact meter
is available with two pulse
inputs, VA and VB, for collec-
tion and remote accumula-
tion of pulses from two water
meters with Reed or elec-
tronic pulse outputs.
Changing between pulse in-
puts and pulse outputs does
not require reconfiguration
of the meter. MULTICAL® 402
is automatically configured
for pulse outputs or pulse
inputs depending on module
choice. Three types of plug-
in modules are available:
Without pulse inputs/out-
puts, with pulse outputs for
energy (CE) and volume (CV)
and with pulse inputs (VA
and VB) for accumulation of
pulses from water meters.
MULTICAL® 402 saves all
consumption data for 15
years, 36 months and 460
days and nights. All log
values can be read via
Kamstrup's hand-held termi-
nal MULTITERM Pro or the PC
program LogView. Further-
more, the info-event logger
saves the latest 50 events.
The 36 newest events can be
displayed. Analysis of these
registers provides a better
overview of the energy con-
sumption through trouble-
shooting, diagnostics and
tamper detection.
Battery supply Set/reset function Remote reading Billing
In addition to 230 VAC or 24
VAC mains modules
MULTICAL® 402 is available
with battery supply. You can
select the D-cell battery with
16 years' lifetime, which
lasts as long as the meter,
or a 6-year 2xAA-cell battery,
which is replaced when the
meter needs reverification.
You can easily replace all
supply modules without
breaking the verification seal
as MULTICAL® 402 is fitted
with a connector for the
supply.
By means of the calculator's
two front keys the installer
can adjust/reset the follow-
ing readings: Time, date,
pulse counter VA/VB, meter
number of connected meter
VA/VB, and primary M-Bus
address.
In addition to wireless and
wired M-Bus you can remote
read MULTICAL® 402 by
means of radio via USB Meter
Reader or hand-held terminal
MULTITERM Pro. Furthermore,
MULTICAL® 402 can be part
of an AMR solution (Auto-
matic Meter Reading), which
automatically reports data
to a central system. An AMR
system covers the utilities'
need for large-scale reading.
Guarantee for accurate meter
data is decisive when it
comes to the consumer's reli-
ance in consumption billing.
It gives consumer satisfac-
tion and secures payments.
The long-term stable and
ultraprecise compact meter,
MULTICAL® 402, provides
you with correct energy con-
sumption any time, and the
consumer can always rely on
the correctness of the bill.
