MULTICAL® 603
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 tem-
perature sensors and flow sensor according to customer
requirements.
MULTICAL® 603 has 2 flow sensor inputs that can be used
for both electronic and mechanical flow sensors. The pulse
figure can 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 m³/h. The calculator can be
delivered with both galvanically connected and separated
flow sensor inputs.
The accumulated heat energy and/or cooling energy can be
displayed in kWh, MWh, GJ or Gcal, all in the form of 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).
MULTICAL® 603 is powered by an internal D-cell lithium
battery with a lifespan of up to 16 years or a 2xAA 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 designing MULTICAL® 603, great importance has been
attached to flexibility through programmable functions
and plug-in modules in order to secure optimum use in a
wide range of applications. The meter has been configured
from the factory and is ready for use. It can, however, be
changed/reconfigured after installation via the front keys
of the meter, READy or METERTOOL HCW.
Auto Detect enables the exchange of ULTRAFLOW® X4
on MULTICAL® 603 without the need for reconfiguration
(change of the CCC code). MULTICAL® 603 can automati-
cally adjust the pulse figure and q
p
to match the connected
ULTRAFLOW® X4 via Auto Detect. Auto Detect is active with
CCC code 8xx and is initiated when the calculator top and
base are separated and reassembled.
