ADS Model 4000 WR (Wireless-Ready)
The ADS Model 4000 WR flow monitor is designed to
communicate through an external, wireless communication device.
Wireless communication occurs through a connection between the
monitor and a CDPD device called the ADS Model 3800
 .
Note: Since the 4000 WR does not communicate using
telemetry, it contains neither a modem board nor a
lightning protection board.
Processor Board
The processor board contains the central processing unit (CPU).
As the source of all monitor activity, the processor board is
responsible for all of the monitor's high-level functions, including
the following:
Controlling user communication with the monitor
Scanning the sensor interface boards and the rain gauge input
to retrieve and store data
