1.3 Device description
ArrowWAN MVM is a compact radio module
for Maddalena series MVM and MVM Plus
C water meters that enables measurement,
transmission and remote reading of the
consumption values and alarms using wire-
less technology.
ArrowWAN MVM is available in two versions:
ArrowWAN MVM169 andArrowWAN MVM 868.
The two versions dier for their transmis-
sion frequency (respectively 169 MHz and
868 MHz) and for the protocol used.
ArrowWAN MVM 169 uses the wM-Bus trans-
mission protocol and also conforms to AF-
NOR E17Z v2.
ArrowWAN MVM 868 uses the LoRa protocol
and is certied by LoRa Alliance®.
This guarantees a high level of interopera-
bility with various reading systems on the
market, including third-party systems.

5
The following alarms are managed: exces-
sive consumption (congurable parame-
ters), backow (limit set and congurable),
leak (congurable parameters), device ge-
neric alarm, battery almost at (below 10%),
electronic fraud and mechanical fraud (re-
moval).
The factory set-up can nonetheless be mod-
ied:
- through the NFC port and relevant app in-
stalled on a device with Android operating
system;
=- through the NFC port and relevant app
via a suitably formatted conguration le
installed on the module.
- OTA if ArrowWAN MVM is already active and
connected to the xed network.
The main technical specications of the
ArrowWAN MVM design are:
– internal sensor that identies rotation of
the pointer on the meter using the prin-
ciple of induction (immune to magnetic
interference), calculates the volume (in
both directions), manages alarms and
stores data in a non-volatile memory;
– wireless radio communication inter-
face:
-ArrowWAN MVM 169 wM-Bus N2 (a, b,
c, d, e, f) conforming AFNOR E17Z V2
which allows for remote reading in both
scenarios, mobile (walk-by) and xed
(AMR);
-ArrowWAN MVM 868 LoRa t 868 MHz
which allows for remote reading in
xed mode only (AMR);
– lithium battery which guarantees a
power supply for up to 15 years. For
ArrowWAN MVM 169 MHz in xed mode
and default parameter conguration.
1.4 Usage limits
The product may be used exclusively with
compatible meters and in line with the cor-
responding usage limits (see paragraph “
Technical specications”).

1.6 Identication
The ArrowWAN MVM module, identied by
the label (A), is strictly associated with a sin-
gle meter. Two elements are required for
this association, performed during installa-
tion: the serial number of the mechanical
meter and the serial number of module
ArrowWAN MVM.

3 Use
The fully operational phase involves remote
meter reading via the radio modules. In
AMR (xed) mode, each radio module tran-
sits the reading with a programmable fre-
quency (default: 3 transmissions per day). In
mobile mode (Walk-By/Drive-By), the radio
module emits a data web with the measure-
ments when it receives a call from the read-
ing kit Maddalena. To receive the signal of
the radio module, go near the meter with
an appropriate receiver, or if a xed (AMR)
reading system is present, the data is col-
lected automatically.
lWARNING!
Reading of data can be per-
formed using various software.
Please consult the metering oper-
ator for more information on the
specic use of reading software.
3.1 Synchronisation of
mechanical reading
The radio module stores the volume record-
ed via an inductive sensor. The module is
set-up in the factory with initial volume at
zero.
If the meter on which the radio module is
installed has a reading other than “zero”, it
may be appropriate to synchronise reading
of the mechanical meter and that of the
radio module using the programming kit.
Simply read the value in litres on the me-
ter and set the reading using the activation
software (refer to the “Activating the radio
module” paragraph).
3.2 Activating the radio module
The radio module is activated through the
NFC port located under the small label
showing the “entry point” logo located be-
side the module’s antenna.
1
lWARNING!
It is necessary to use a smart-
phone with the Android operat-
ing system and the relevant app
provided by Maddalena S.p.A..
The app must be installed and set
correctly before proceeding with
the activation of ArrowWAN MVM.
Refer to the app’s manual for the
details.

lWARNING!
ToactivatetheArrowWAN MVM169
module, set the radio type in wM-
Bus
ToactivatetheArrowWAN MVM868
module, set the radio type in
LoRa.
To set the type of radio, click on the three
dots at the top right-hand side (2) and
choose SETTINGS. Check that the correct
radio type (wM-BUS or LoRa) was selected
in the “Application Mode” eld. Moreover,
make sure that the “Headend Mode” is not
agged, since the ArrowWAN MVM radio
does not use this option.
lWARNING!
When changing the type of radio,
it is necessary to close the app
and repeat the login
2
During activation, 3 parameters are re-
quested: the serial number of the mechani-
cal meter, the pulse weight and the reading
of the volume measured by the meter ex-
pressed in litres.
Once these preliminary operations have
been completed, proceed as follows:
– Enable the smartphone’s audio function;
– Open the “Wirgrid NFC” application;
– Enter the “Login” and “Password”;
– Verify that the correct radio was set in the
“Application mode” eld under SETTING;
– Place the smartphone above the radio
module (3) to allow the NFC communica-
tion;
3
– Wait for the “beep”. This will signal that
the NFC communication is active. At this
point, the smartphone can be moved;
– Make sure that “Headend not use for in-
stallation” (4) appears on the display;

12
– Enter the missing parameters (indicated
with a red icon);
-“Index” (reading of the mechanical me-
ter)
-“Pulse value” (pulse weight: 1 l for DN
up to 32 mm and 10 l for DN 40 mm)
-“Meter ID” (serial number of the me-
chanical meter associated with the ra-
dio)
– If necessary, modify the entered default
parameters (indicated with a green icon)
“Fluid type”, “Installation delay”, “Collect
mode”;
lWARNING!
The “Collect mode” parameter is
set by default to “Fixed”.
If module ArrowWAN MVM 169
is activated, the radio type can
be set to “Fixed” (AMR mode for
xed network), “Mobile” (mobile
reading mode) or “Both” (AMR
mode for xed network and mo-
bile reading mode)
If module ArrowWAN MVM 868 is
activated, the radio type can be
set solely to “Fixed” (AMR mode
for xed network)
– Place the smartphone above the radio
module to allow the NFC communication;
– Click “INSTALL MODULE” (5) once all the
parameters have been inserted correctly;
5
– Wait for the activation (6) to terminate;
6

13
– Once completed, the “Installation suc-
cessful” (7) message will appear.

lWARNING!
The radio module is pre-cong-
ured. To change the settings,
refer to the manual of the activa-
tion and programming app.
3.3 Verication of the entered
parameters
Use the “Summary” function to verify that
the “module serial number”, “reading” and
“pulse weight” values have been entered
correctly.
From the “Install” menu, click “Summary”
(1) to view the information of the installed
modules (2).

4 Maintenance
4.1 Battery
The radio module is equipped with a 3.6 V
lithium-thionyl chloride (Li-SOCl2) battery
that is not rechargeable but can be replaced.
Its useful life varies between 12
(ArrowWAN MVM 169 mobile + xed) and
15 years (ArrowWAN MVM 169 xed, three
transmissions per day of the measurements
plus one weekly transmission on the status
of the module) with the factory set up in the
following operating conditions:
– between -10°C and +0°C for 10% of
lifespan
– between 0°C and +30°C for 80% of lifespan
– between +31 °C and +55 °C for 10% of
lifespan
lWARNING!
Humidity and intense heat may
damage the battery and reduce
its lifespan.
The radio module calculates the residual
lifespan of the battery on the basis of stored
parameters, such as estimated consump-
tion of the electronic board in stand-by
mode, transmitter consumption and num-
ber of transmissions performed.
Battery life depends largely on the frequen-
cy of data transmission set.
4.2 Cleaning
No particular cleaning procedures are
required. However, the installation area
should be kept clean and periodic checks
should be performed to ensure the re-
quired environmental conditions are met.
dPROHIBITED
Use of abrasive products, petrol
or trichloroethylene is not per-
mitted.
4.3 Disposal
The device is composed of materials of vari-
ous nature including metal, plastic and elec-
trical and electronic components. It must be
disposed of in compliance with applicable
local laws regarding special and industrial
waste. The device cannot be disposed of as
domestic waste.
At the end of the product’s life, ensure safe
removal and responsible disposal of com-
ponents, including recycling of batteries, in
compliance with applicable environmental
laws in the country of installation.
