The EchoSmart Sludge Blanket Monitor is an underwater, interface-level analyzer built on a digital platform with technology that allows us to locate the analyzer in the sensor. Sensors generate and process the ultrasonic signal for continuous, real-time measurement, resulting in greater flexibility in equipment configuration options, enhanced communication capabilities and reduced installation costs.
EchoSmart is an underwater interface-level analyzer technology that is built on a digital platform. This allows the analyzer to be located in the sensor. The result is greater flexibility in equipment configuration options, enhanced communication capabilities and reduced installation costs. EchoSmart Interface Level Analyzers are unique in that our Smart-Sensor technology enables the control and monitoring of up to 16 Smart Sensors from one EchoSmart Controller. This allows for field networks of sensors, thereby lowering the ‘per-tank’ cost. These field networks can also be created wirelessly, eliminating costly conduit and cabling runs.
EchoSmart is adaptable and can be programmed to suit various tank sizes and designs. Three sensor models provide a solution for most applications: the standard sensor with multi-flex assembly for when surface skimmers are present, the self-cleaning sensor for applications without surface skimmers, and the sensor with turbidity that offers further insight into water clarity.
How do I calibrate the EchoSmart sensors?
The sensors require no calibration. The sensor’s ultrasonic design is already customized for the application and therefore requires no calibration.
How often do the EchoSmart sensors need to be cleaned?
It is recommended that the sensors be inspected frequently the first 3 to 6 months to establish the necessary cleaning regimen for the specific application. Ensuring the measurement surface of the sensor remains clear of any buildup (and that the wiper arm is allowed to rotate freely, when applicable) will allow for uninterrupted performance.
Is it possible to see both the blanket level and the dispersed solids above the blanket?
When the sludge is well-settled, yes. The displayed measurement will be the sludge level and the dispersed solids can be visually observed on the Tank View screen and is additionally available for output via Modbus or a 4-20mA output.

Is it possible to utilize the wireless field network and get the measurement at our control system via 4-20mA outputs?
Yes. A digital-to-analog (Modbus to 4-20mA) sixteen-channel converter is available for purchase. This device utilizes the Controller’s ability to wirelessly retrieve data from each sensor and then converts those values to individual and configurable 4-20mA outputs.
