1.3 Device description
ElecTo SONIC is a static cold water meter.
It measures the ow volume, ow rate and
other parameter values using ultrasonic
technology. The meter continuously moni-
tors the status of operating and installation
parameters. In the event of a fault, it trig-
gers and sends the dedicated alarms.
ElecTo SONIC is equipped with an integrat-
ed radio which uses Wireless M-Bus and
LoRaWAN technology allowing remote data
transmission. Data can be received using a
special mobile reading kit or via concentra-
tors and a xed network.
The main technical features of ElecTo SON-
IC are:
– Liquid crystal display;
– NFC interface for device conguration;
– Protection class IP68;
– Accuracy class up to R800;
– Fault reporting. Reporting of abnormal
water consumption and error detection
(see Alarms);
– Absence of moving parts. Resistance to
wear and constant functioning over time;
– Datalogging functionality. Historic val-
ues are available relating to: current vol-
ume, backow volume, minimum and
maximum ow rate, water temperature;
– Power supply. Long-lasting lithium bat-
tery (depending on the set conguration);
– Available with built-in wM-Bus and/or
LoRaWAN 868MHz radio communica-
tion.

The 9 digit LCD shows the data on volume
and ow rate cyclically, as well as any active
error codes.
The display is set in xed mode with the fol-
lowing automatic display cycle:
– for 60 seconds, the Main view;
– for 12 seconds, the Periodic readings;
– for a further 12 seconds, the Display Test
and rmware version.
Icon Description
Test
Activated during test mode
Error
Activated when an error is displayed
Transmission antenna
Signals radio transmission or radio
enabled
Calendar
Activated when billing dates are
displayed
Battery
Activated when the calculated service
life is coming to an end or when the
voltage drops below the minimum
value (in which case the error icon
also lights up)
No ow indicator
Activates when no instrument ow
rate is detected
Leakage
Activated when the leakage alarm is
triggered
Backow
Activated when the reverse ow
alarm is triggered
Star indicator
The indicator, consisting of 2 arc
segments, follows the ow by ro-
tating clockwise for direct ow and
anticlockwise for reverse ow

1.7.1 Main view
– The volume measured is displayed for 12
seconds;
– The ow rate is displayed for 3 seconds;
– The display cycle is automatically repeat-
ed 4 times, for a total of 60 seconds (12+3
=15 x 4 =60).
1.7.2 Periodic readings
Following an automatic sequence, billing
date references are displayed:
– Date of reading 1 displayed for 3 seconds;
– Periodic reading 1 displayed for 3 sec-
onds;
– Date of reading 2 displayed for 3 seconds;
– Periodic reading 2 displayed for 3 sec-
onds.
The calendar icon is active during the dis-
play.
1.7.3 Display test and rmware version
The display is presented as follows:
– all segments active for 3 seconds;
– all segments o for 3 seconds;
– the installed rmware version is dis-
played for 3 seconds. The displayed for-
mat is MM.mmF, in which MM indicates
the number (2 digits) of the main version,
mm indicates the number (2 digits) of the
secondary version and Frepresents the
rmware;
– the rmware CRC for 3 seconds. The for-
mat displayed, using all 8 digits of the
display, is 32-bit hexadecimal using both
digits and letters (0-9/A-F);
– any error codes for 3 seconds (e.g. Err
XXXX, where XXXX is the hexadecimal code
for the error). See table "Error codes".
1.7.4 Seals
The meter has a hole (1) at the side of the
body, which is designed for inserting a wire
seal when installing on site.
