Sewer measuring boat

The sewer measuring boat can be used in sewers from DN 700 (28'') to DN 2000 (80''). It floats on the wastewater and uses sensors to measure the height of the wastewater and the settled deposits in the pipe. The stored sensor data is later processed to obtain a precise determination of the deposit situation within the sewer line.

However tough, the sensors do need to be manually re adjusted when the size and shape of the pipe changes. The use of the measuring boat is not possible when wastewater level is too high or too low [Loren98b].
