InfoSense

InfoSense, Inc. is a technology-driven C-corporation spun out of the University of North Carolina at Charlotte to commercialize a promising acoustic inspection technology developed by a faculty member in the electrical and computer engineering department. This patented technology uses sound waves to non- invasively detect blockages in segments of sewer collection pipe by quickly inserting a portable transmitter and receiver into either end of the pipe or through a network of stationary devices that can maintain continuous assessment. The innovation of the underlying technology lies in the fact that this product uses an active transmit and receive process to assess pipe blockage conditions as compared to the reflective nature of similar applications such as SONAR. The active transmit and receive process works extremely well in gravity-fed sewers and pressurized pipes to detect abnormalities in a simple, low cost, and straightforward way.

InfoSense’s name is derived from a blending of the words “Information” and “Sensors” reflecting their motivation to create new acoustic sensor applications. When developing new applications, InfoSense partners with water and wastewater industry leaders to jointly find unique and exciting solutions to their problems. An example of this is their Award Winning Sewer Line Rapid Assessment Tool, or SL-RAT, which was created in partnership with a leading utility to provide critical sewer system condition assessment information quickly and efficiently. The SL-RAT has inspected over 2.5 million feet of pipe and won the prestigious Water Environment Federation Innovative Technology Award in 2012. Utilities around the world have begun using the SL-RAT to objectively focus their sewer cleaning and camera inspection activities on “problem” pipes thus reducing Sanitary Sewer Overflows, improving operational efficiency, and bettering our global environment.

SL-RAT

The SL-RAT is a highly portable onsite assessment tool that provides a sewer line blockage assessment in less than 3 minutes. The SL-RAT is composed of two components – the Transmitter (or TX unit) and the Receiver (or RX unit). Each SL-RAT device is sold or leased as a uniquely configured “pair” – with the TX providing the active acoustic transmission through the pipe (think of the TX as “yelling” down the pipe) and the RX providing the microphone and signal processing capabilities to listen and interpret the received acoustic signal (think of the RX as the brain “listening” for the blockage and processing the blockage assessment result). Additionally, each SL-RAT component is equipped with GPS and the ability to communicate between the TX and RX via RF – thus providing your organization with world class data labeling, data registration, and test validation capabilities.
