Device description
Arrow
EVO
Standalone is a radio module with
pulse input compatible with
Maddalena
wa-
ter meters and with those of other brands.
The device allows for measuring, transmit-
ting and remotely reading the consump-
tion values and the alarms using a wireless
transmission technology.
The following alarms are managed: maxi-
mum flow exceeded (limit can be activated
and configured), backflow (limit set and con-
figurable), leak and mechanical fraud (cable
cutting).
Arrow
EVO
Standalone is compliant with the
wM-Bus data communication protocol de-
fined at European level by Standard EN
13757. This guarantees a high level of inter-
operability with various reading systems on
the market, including third-party systems.
Arrow
EVO
Standalone is also OMS certified
(www.oms-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
Ar-
row
EVO
Standalone design are:
–
input via four-pole cable of the follow
-
ing signals:
pulses (flow meter revolu-
tions), flow direction, anti-fraud, earth.
Thanks to these data, the module calcu-
lates the volume (both directions), man-
ages alarms and memorises the data in a
non-volatile memory;
– M-Bus (EN 13757) 868 MHz
radio wire-
less communication interface that
allows remote reading in both
mobile
(walk-by) and
fixed (AMR) scenarios, us-
ing the same factory set-up (transmission
interval);
–
lithium battery that guarantees long-
term power supply (15 years + 1)
–
support ring nut
that allows the module
to be attached to the QuadraPlus sensor
easily. Alternatively, it can be fixed to the
wall using the two plugs supplied or to the
pipe using clamps.
