Internal voltage 3.6 V by the battery or plug-in power supply module

Battery, 3.6 V type (option)

3.6 V lithium D-cell, battery lifetime typically 16 years with independently powered flowmeter

230 V AC module (option)

Plug-in module for 230 V AC (195 ... 253 V AC), 50/60 Hz (incl. battery backup)

24 V AC module (option)

Plug-in module for 24 V AC (12 ... 30 V AC) (incl. battery backup)

Battery backup (option)

Only with mains supply modules by internal 3.0 V lithium battery (type CR 2032)
Displayed values, date and time are still updated, but the measuring functions have stopped, including the flow rate measurement. Communication via optional modules M-Bus, RS 485, RS 232 or optical interface is maintained, affecting the backup battery lifetime.



Accessories/Software

The parameterization software based on the M-Bus is a convenient tool for handling the calculator. It runs on Windows and is used for configuration of the calculator functionality, reading out different memories, printing out calculator logs. For further details please contact your local Siemens representative.

A specific optical head with a permanent magnet in (IrDA adapter with bluetooth) accordance with EN 1434 can be used for programming/altering programming of readout data, configuration data, etc. The reader head can also be used to change measuring data.
