The Badger Meter EchoSmart Sludge Blanket Monitor is an underwater interface-level analyzer designed for continuous sludge blanket level measurement.
Its digital Smart-Sensor design places the analyzer technology within the sensor, where ultrasonic signals are generated and processed.
The system supports flexible equipment configurations for tanks of different sizes and designs.

A single EchoSmart Controller can control and monitor up to 16 Smart Sensors, with wired or wireless field-network options available for connecting multiple monitoring points.
