2000 – Ultrasonic heat meter
INFOCAL 6 Calculator
The calculator contains all the necessary circuits
for recording the flow rate and temperature as
well as for calculating, logging and displaying
the data. The calculator housing can be mounted
directly on the flow sensor or on the wall. At
application with medium temperature above
90 °C or at temperatures T
water
< T
environment
the
calculator has to be removed from the flow
sensor. The calculator can be conveniently read
from a single line 7-digit display with units and
symbols. A push-button provides user-friendly
control of the various display loops. All failures
and faults are recorded automatically and shown
on the LC display. To protect the reading data,
all the relevant data are saved in a non-volatile
memory (EEPROM). This memory saves the
measured values, device parameters and types
of error at regular intervals.
Temperature Sensors
Pairs of Pt 100 or Pt 500 temperature sensors
with 2-wire leads are used.
Interfaces
INFOCAL 6 is equipped as a standard with a ZVEI
optical interface with the M-Bus protocol acc. to
EN 1434.
This interface is used, for example, for
communication with the HYDRO-SET
parameterization software. The calculator
features 2 slots for the modules. One slot
for the function modules, and one for the
communication modules.
The following communication modules are
available as options:
- RS232 module;
- M-Bus module acc. to EN 1434;
- Real Data Radio Module.
The RS 232 communication module is a serial
interface and permits data exchange with the
calculator. For this purpose a special data cable is
necessary.
The M-Bus module is a serial interface for
communication with external devices (M-Bus
Repeater) e.g. HYDRO-CENTER. A number of
calculators can be connected to a control centre.
The Radio module is an interface for
communicate unidirectional over radio
predefined data records. The protocol is send
every 8 … 19 s. For receiving there are different
Hydrometer receiver available. The transmission
protocol is editable by HYDRO-SET. If battery
supplied the life time is up to 8 years.
