2.Hydrometers and Irrigation Controllers ARAD Hydrometers (electronic flow meters/ master valves) monitor and measure the flow rate remotely. Old generation irrigation controllers (Scorpio, MIR 500) were upgraded to new generation (XM, ACE, M) which have Ethernet and radio capabilities and have reliable communication.

3. Software Update Benefits and advantages of the new Motorola ICC Pro 3: • Muti-User programming for Housing and Athletics • Improved data collection • Monitoring water use down to the valve level • User friendly and easy to navigate • & more!
The user-friendly interface of the new software makes it easy to look at the parameters measured at each weather station
The new software is able to graph and chart metrics like ET daily
