General
description
MULTICAL®
603
is
an
all
‐
round
calculator,
suitable
as
heat
meter,
cooling
meter
or
combined
heat/cooling
meter
together
with
1
or
2
flow
sensors
and
2
or
3
temperature
sensors.
The
meter
is
intended
for
energy
measurement
in
almost
all
types
of
thermal
installations
where
water
is
used
as
the
energy
‐
conveying
medium.
MULTICAL®
603
can,
in
addition
to
heat
and
cooling
measurement,
be
used
for
leakage
monitoring,
permanent
performance
monitoring,
as
power
and
flow
limiter
with
valve
control
as
well
as
for
energy
measurement
in
both
open
and
closed
systems.
According
to
EN
1434
and
MID,
MULTICAL®
603
can
be
designated
as
a
“calculator”
with
separate
type
approval
and
verification,
and
it
can
be
delivered
either
as
a
separate
calculator
or
as
a
complete
meter,
with
mounted
temperature
sensors
and
flow
sensors
according
to
customer
requirements.
The
MULTICAL®
603
calculator
top
can
be
separated
from
the
connection
base
without
using
tools
when
the
installation
seals
are
broken.
This
provides
free
access
to
the
installation
of
the
flow
sensor,
temperature
sensors,
power
supply/battery
and
communication
modules.
The
calculator
top
is
factory
‐
sealed
and
may
only
be
opened
by
authorised
meter
laboratories.
If
the
factory
seal
is
broken,
the
factory
guarantee
no
longer
applies.
MULTICAL®
603
has
2
flow
sensor
inputs
that
can
be
used
for
both
electronic
and
mechanical
flow
sensors.
The
pulse
figure
cab
be
programmed
from
0.001
to
300
pulses/liter,
and
the
calculator
can
be
programmed
to
all
nominal
flow
sensor
sizes
from
0.6
to
15,000
m
3
/h.
The
calculator
can
be
delivered
with
both
galvanically
connected
and
separated
flow
sensor
inputs.
The
temperature
measurements
in
inlet
and
outlet
are
performed
with
accurately
paired
Pt500
or
Pt100
sensor
according
to
EN
60
751
and
EN
1434.
MULTICAL®
603
normally
comes
with
a
Pt500
sensor
pair,
e.g.
short
direct
sensors
according
to
EN
1434
‐
2
or
ø5.8
mm
sensors,
which
fit
Kamstrup
sensor
pockets
in
stainless
steel.
MULTICAL®
603
can
also
be
delivered
with
4
‐
wire
temperature
sensor
inputs
that
are
especially
suitable
for
installations
with
long
temperature
sensor
cables.
Accumulated
heat
energy
and/or
cooling
energy
can
be
displayed
in
kWh,
MWh,
GJ
or
Gcal,
all
with
seven
or
eight
significant
digits
plus
measuring
unit.
The
display
has
been
specially
designed
with
a
view
to
obtaining
long
lifetime
and
sharp
contrast
in
a
wide
temperature
range.
Furthermore,
MULTICAL®
603
can
be
delivered
in
a
variant
with
backlit
display
(type
603
‐
F).
Other
reading
options
are:
accumulated
water
consumption,
operating
hour
counter,
error
hour
counter,
current
temperature
measurements,
current
flow
and
power
readings.
Furthermore,
MULTICAL®
603
can
be
configured
to
display
monthly
and
yearly
loggings,
target
date
data,
max/min.
flow,
max/min.
power,
information
code,
current
date
as
well
as
user
‐
defined
tariffing.
MULTICAL®
603
is
powered
by
an
internal
D
‐
cell
lithium
battery
with
a
lifespan
up
to
16
years
or
a
2xA
lithium
packet
with
a
lifespan
of
up
to
9
years.
Alternatively,
the
meter
can
be
mains
supplied,
either
by
24
VAC
or
230
VAC.
In
addition
to
the
energy
meter’s
own
data,
MULTICAL®
603
can
display
the
accumulated
consumptions
of
two
extra
water
meters,
e.g.
cold
and
hot
water
meters,
which
supply
a
pulse
signal
to
MULTICAL®
603
via
reed
‐
switch
or
electronic
output.
The
contact
signals
from
the
extra
water
meters
are
connected
via
the
communication
modules.
A
multiple
plug
placed
behind
the
seal
is
used
in
connection
with
calibration
and
adjustment
during
verification
as
well
as
in
connection
with
communication
modules.
MULTICAL®
603
is
available
with
1
or
2
communication
modules
for
Wireless
M
‐
Bus,
M
‐
Bus
and
RS232.
The
modules
are
available
with
either
pulse
inputs
or
pulse
outputs.
Furthermore,
the
meter
can
be
delivered
with
integrated
M
‐
Bus,
independent
of
the
modules.
In
designing
MULTICAL®
603,
great
importance
has
been
attached
to
flexibility
through
programmable
functions
and
plug
‐
in
modules
(see
paragraphs
3.2
and
11)
in
order
to
secure
optimum
use
in
a
wide
range
of
applications.
In
addition,
the
construction
makes
it
possible
to
update
previously
installed
MULTICAL®
603
via
the
PC
‐
program
METERTOOL
HCW.
