Arrow
WAN
is a radio module with pulse input
compatible with
Maddalena water meters
and with those of other brands. The device
allows for measuring, transmitting and re-
motely reading the consumption values and
the alarms using a wireless transmission
technology.
Arrow

169 uses the wM-Bus transmis-
sion protocol and also conforms to AFNOR

certified by LoRa Alliance®.
This guarantees a high level of interopera-
bility with various reading systems on the
market, including third-party systems.
