2 Installation
2.1 Receipt of the product
1x
Optional accessories:
– Fittings kit
– Gasket kit
– Gasket
– Non-return valve
lWARNING!
The instruction manual is an inte-
gral part of the device and should
therefore be read and stored
carefully.
dPROHIBITED
Packaging material must be prop-
erly disposed of and kept out of
children’s reach as it may repre-
sent a hazard. Disposal must be
performed in line with applicable
laws.
2.2 Assembly
Authorised personnel: specialised installer
or plumber, assigned by the metering oper-
ator.
lWARNING!
Only authorised and suitably
trained personnel with sucient
technical experience may install
and operate the device.
Before installing the device, make sure that
the two sections of tube are even to prevent
mechanical stress, clean them with care (es-
pecially in the case of empty tubes) and let
water run for a while, using a stub pipe on
the tube instead of the meter.
If there is no water in the pipeline, open the
valve upstream of the device before install-
ing it. This is necessary because opening
the valve after installation is complete may
cause air suction that could damage the de-
vice.
Before using the meter, rst fully remove air
from the pipe and the device itself. The in-
terception/adjustment valves must be fully
open when doing this. Open the valve at the
start rst and then the valve at the end.
When replacing the meter, it is recommend-
ed to replace the gasket on the tting. Rec-
ommended gasket hardness: minimum 80
Shore A.
Tighten the nut with a torque wrench and
use a counter wrench to hold the meter in
position. Maximum tightening torque: 40
Nm.

13
Install the meter:
– protected from frost (insulate it if necessary with insulation material) and in the lower
part of the system to prevent air accumulation;
– protected from blows and tampering, where readings are easy to make;
– so that the direction of the arrow on the device coincides with the ow direction.
Install proper interception valves upstream and downstream of the meter to permit main-
tenance operations and inspections on the device, as well as to check the system.
The installation of a non-return valve inside or outside the meter is also recommended (see
dedicated data sheet).
lWARNING!
Before positioning the seal, make sure that it is not damaged.
Make sure that the seal is not damaged during installation.
Make sure that the level of the seal matches that of the tubing.
Check that the seal does not protrude from the tube.
Make sure that the surfaces of the ange are clean and undamaged.
lWARNING!
Check the seal hold to prevent leakage.

14
Installation position
Observe the indications on the dial (letters
H and V):
– H: the meter must be installed with the
dial in a horizontal position;
– V: the meter must be installed with the
dial in a vertical position;
– H and V: the meter may be installed with
the dial in either a horizontal or vertical
position;
– If not shown, avoid vertical installations
with downward ow, or with the dial fac-
ing downwards.
Straight sections and ow straighteners
When using straight sections upstream and/
or downstream of the meter, refer to letters
U and D on the dial. If the letters U and/or
D are followed by the letter S, install a ow
straightener.
Allowable water pressure (ISO 4064-1)
The maximum allowable pressure (MAP) is
16 bar, and is displayed on the meter dial. If
not indicated on the dial, it must be 10 bar.
These values must never be exceeded.
The maximum allowable pressure (MAP)
downstream of the meter must be greater
than or equal to 0.03 Mpa (0,3 bar).
Commissioning
Before putting the meter into operation,
completely vent the air from both the pipe
and the meter itself (rotate it if necessary).
The interception/adjustment valves must be
fully open when doing this. Open the valve
at the start rst and then the valve at the
end.

15
3 Use
ElecTo SONIC is ideal for domestic and in-
dustrial usage and, thanks to the absence
of moving parts, it is resistant to wear and
ensures constant functioning over time.
The measurements taken by the meter are
shown cyclically on the display and are also
available on other communication interfac-
es.
The water meter is not suitable for installa-
tions where the water is particularly heavy,
sandy, rich in algae, sludge and debris, or
contains air.
The normal operating phase is remote me-
ter reading through radio modules. In AMR
(xed) mode, each radio module (wMBus
and/or LoRaWAN) transmits the reading at
a programmable frequency.
In mobile mode (Walk-By/Drive-By), the ra-
dio module wMBus emits a data frame with
the measurements. To receive the radio
module signal, hold a suitable receiver near
the meter. The xed (AMR) system reads
data automatically.
lWARNING!
Data can be read using a variety
of software. Please refer to the
accounting manager for specic
usage information on the reading
software.
lWARNING!
It is recommended to keep the lid
closed once the installation steps
are completed.
4 Conguration
ElecTo SONIC is supplied with a default
conguration.
The radio is activated after the passage of
10 litres of water.
The NFC programming interface is available
at all times by positioning the special set-
tings kit above the designated area. The to-
tal available cumulative programming time
is 18 hours.
NFC Ar
ea
The radio settings, such as the type of ra-
dio frame and data transmission frequen-
cy, have a default factory setting. However,
they can be changed, if necessary, after
making the device programmable, via the
appropriate kit:
– App ElecTo SONIC (Android, downloada-
ble from Google Play Store);
– Smartphone with NFC or UniCo Tool inter-
face.
For further information, contact the manu-
facturer.
The app allows the following parameters to
be read and programmed:
– Radio settings
– Radio AES key
