Calculator

The calculator contains all necessary circuits for
recording flow rates and temperatures, and for
calculating, logging and displaying the data.
The calculator housing can be mounted on the
wall or standard DIN rail.
The calculator can be conveniently read from
an 8-digit display with units and symbols. Two
push-buttons provides user-friendly control of
the various display loops.
All failures and faults are recorded automatically
and shown on LCD display.
To protect the reading data, all 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 500 Ø5.2 mm (or Ø6.0 mm)
temperature sensors with 2-wire (or 4-wire)
leads can be used. Cable lengths of 3 m, 5 m and
10 m are available.

Optical interface

Optical interface is integrated into the front
panel of the calculator. It is designed for data
reading via M-bus protocol.
The optical interface is activated by pressing the
control button, and it automatically shuts off
5 minutes after the button has been activated

Wired M-Bus interface

The energy meter has one slot for an additional
communication module. The internal M-Bus
module provides data reading possibility via
M-Bus protocol:

• M-Bus protocol according to EN13757-3
standard

• 2-wire with polarity reversal protection

• Electrical isolation

• Maximum voltage 50 V DC

• Current drawn: one M-Bus load (1.5 mA)

• Primary or secondary addressing

• Baud rate 300/1200/2400/4800/9600 (default:
2400 baud rate)

• Battery lifetime min. 12 years ( D cell)

• Fastest reading interval at battery supply: one
meter on the bus every 280 seconds (2400
baud rate)

• Fastest reading interval at mains supply: no
limits

Radio OMS 868.95 MHz interface

The module can provide data reading via radio
module:

• Wireless M-Bus protocol according to

EN13757- 4

• OMS (open metering system) compatible

• 868.95 MHz, T1 mode (unidirectional)

• Sending interval every 90 seconds (suitable for
‘walk by’ readings)

or after data transmission via interface is
completed.
