1.3 Device description

Arrow is a compact radio module for
EVO
Maddalena MVM, MVM Plus C and WMAP
Evo cold water meters that allows for re-
motely measuring, transmitting and reading
the consumption values and the alarms us-
ing wireless technology.
The following alarms are managed: maxi-
mum flow exceeded (limit can be activat-
ed and configured), backflow (limit set and
configurable), leak, electronic fraud and me-
chanical fraud (removal).
Arrow is compliant with the wM-Bus data
EVO
communication protocol defined at Europe-
an level by Standard EN 13757. This guar-
antees a high level of interoperability with
various reading systems on the market, in-
cluding third-party systems.
Arrow is also OMS certified (www.oms-
EVO
group.org).
The factory set-up can be modified via radio
signal at a later point using the special con-
figuration kit (USB transceiver and relative
software), supplied separately.
The main technical specifications of the
Arrow design are:
EVO
– internal sensor that identifies rotation of
the pointer on the meter using the princi-
ple of induction (immune to magnetic in-
terference), calculates the volume (in both
directions), manages alarms and stores
data in a non-volatile memory;
– M-Bus (EN 13757) 868 MHz radio wireless
communication interface that allows
remote reading in both mobile (walk-by)
and fixed (AMR) scenarios, using the same
factory set-up (transmission interval);
– lithium battery that guarantees long-
term power supply (15 years + 1)
