Water Savings – ET-based (multiple weather station options)
Eective ET-based system management can lead to water savings of
25% to 30% per year. As an additional source of savings, pipeline breaks,
malfunctioning valves, and missing heads are automatically detected and
shut down, preventing excessive water loss.

Distributed Intelligence
Each Sentinel
®
controller is a fully intelligent unit with program data stored
at both the field satellite and within the central computer. In the event a
computer or master controller goes o line, there will be no loss of irrigation.
True two-way communication allows programming changes to occur at the
on-site field controller and uploaded to the central computer. Protection from
unauthorized changes is ensured as the controller program can be easily
compared to the program saved in the central computer.
