ARM
Multiprobe MP ARM Automatic River Monitoring DR discharge radar
   
ARM is the first product of Extratech dedicated to remote monitoring of surface water and groundwater. The combination of multiple sensors makes ARM a versatile monitoring system and extremely configurable according to specific customer requirements.

With ARM you can handle both analog and digital sensors and what makes this innovative system a useful garrison and structural environmental safety, for example, you can also check any rotations, movement or subsidence of hydraulic infrastructures.

The measuring and monitoring system consists of:
- A turbidity sensor for the measurement of suspended solids with the back-scattering technique
- A dual radar for measuring the water level and the surface speed
- Acquisition and remote control unit
- Multiparametric probe (optional)
- Other choice sensors (optional)
- Photovoltaic power supply kit (optional power supply)

A modular hardware architecture and expandable ago ARM a higher-level monitoring station with the best quality / price on the market.

ARM is controllable by the customer through a platform Web and even from smartphones using Android application. THE measured data are sent via the GPRS module Integrated, Web portal, where customers can query the active monitoring system and display the measures both tabular and graphic.
ARM - Automatic River Monitoring
 
The Automatic river monitoring system ARM is controllable via secure access from web or smartphone apps.
