ADS Model 4000
A permanent flow monitor for sanitary sewer applications
The ADS Model 4000 is a battery powered flow monitor that has set the industry standard for open channel flow measurement performance and reliability. In a permanent network often number over 100 individual units, the Model 4000s acquire highly accurate depth and

velocity data in sewerlines from 8" to 110" in diameter.
The Model 4000 communicates through standard telephone telemetry or wireless services to a remote computer or Web-hosted software interface. For a standard configuration, the Model 4000 operates with ADS Quadredundant ultrasonic depth, peak velocity and pressure depth sensors. The Model 4000 flow monitor specifications for accuracy have been tested and verified by the EPA's
Environmental Technology Verification (ETV) program.
Features of the Model 4000:
- Monitor Level Intelligence (MLI) for optimizing sensor accuracy
