Reliable Flood warning and Disaster management communications

ERT-A2 Network


ELPRO’s Industrial Wireless Solutions has 30 years of expertise in
solving critical industrial communications in flood warning applications.
The ERT-A2 is a new generation ground up redesigned
product that extends on the successful ERRTS™ product line.

Designed to meet local conditions the ERT-A2 provides a single
product to support remote stations, repeater and base receiver
applications. Supporting a large variety of environmental sensors,
critically rain fall, river height gauging data collection to
support environmental, flood warning and SCADA applications.

The ELPRO ERT-A2 remote station-repeater in a single unit provides
the flexibility in mounting, sensors and power sources required
to support installations in sometime very remote or citybased
situations in traditional tree, platform, or cabinet.
