COMBINING INSPECTION SENSORS, CAN HELP TO REDUCE REPAIR COSTS AND MINIMIZE DOWNTIME BY IDENTIFYING ISSUES MORE ACCURATELY AND QUICKLY. MUNICIPALITIES CAN MAKE REPAIRS MORE EFFICIENTLY AND WITH LESS DISRUPTION TO THE SEWER SYSTEM.

AquaCoustic’s camera is designed for ocean deployment; as such, back scatter from suspended particles has been minimized. Where fogging in the pipeline is an issue we have also added lights that are positioned to minimize backscatter and pick up pipe wall details.Our lights also produce illumination that has the same color temperature as sun light on a partially cloudy day. This produces more accurate substrate colors.

Benefits of Time of Flight laser:

Distance measurements are acquired by measuring the time it takes for the laser light to bounce off a target and return to its origin. Because light speed is constant, distance can be determined from the so-called “time of flight.” of the laser pulse. Measurements are made with respect to line-of-sight to the laser origin, so it allows for large changes in range such as traversing manholes. The unit reliably detects objects independent of the surface and ambient light. An accuracy of 8 mm is consistent no matter the range (from 5 cm to 25 m). The strength of the reflected light can be used to identify cracks, water infiltration and even spray-painted information in the pipe. (Light materials reflects more energy than dark material and a grey scale image can be produced)
