Design and function	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 or after data transmission via interface is completed.

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)
