• Mail and messaging (SMS) functions
– Measuring device configuration
– Measuring device diagnostics
– Flow protocol data (automatic transmission)
– Totalizer: positive/negative/net values (balance) (automatic transmission)
– Alarms (at the time of the event)
Signal on alarm Status/pulse output
“Not conductive” in the event of fault or power supply failure
Low flow cutoff Switch points can be selected for low flow cutoff between 0 and 25 % of the full scale value.
Galvanic isolation All circuits for inputs, outputs and power supply are galvanically isolated from each other.
Data logger (SD card) • The integrated data logger can log the following data:
– Reference data: time, date, consecutive numbers in list etc.
– Totalizer counter readings: positive, negative, net (balance)
– Flow: in volume unit (e.g. m3/h) or in %
– Measuring cycles per hour, state of charge of the individual battery packs (B1, B2, B3),
temperature of the electronics board
• Configurable save cycle: 15 seconds to 24 hours.
• The data of the data logger are not lost if the battery is replaced.
The data logger gives users the option of second, parallel data recording in a higher resolution within
a specific period of time.
The data are saved daily in a new file on the micro SD card (storage capacity 2 GB). Via the FXA291
service interface, the files can be saved for evaluation on a PC or laptop with the Config5800 operating
software. It is also possible to transmit the files by e-mail via the GSM/GPRS modem, which is available
as an option.
Power supply
Battery concept Battery arrangement options
Three battery terminals are available in the measuring device. These terminals are assigned different uses
depending on the number and arrangement of the batteries. B1 and B2 are the terminals for power supply to
the measuring device, B3 is the terminal for the GSM/GPRS modem.
The measuring device is initially powered by the batteries in terminal B2. If the voltage supplied by these
batteries becomes too low, the measuring device issues a message and switches automatically to the battery in
terminal B1.
If power is supplied to the measuring device externally and the power supply fails, the battery in terminal B1
acts as a backup power supply.
The GSM/GPRS modem is always powered by the battery in terminal B3.
