IMPROVED APPARATUS AND METHODE FOR MEASURING AND MONITORING THE WATER HEIGHT LEVEL AND CORRESPONDING VOLUME OF OVERFLOW WATER IN SEWER OVERFLOW CHAMBER

摘要

A video apparatus for measuring and monitoring the water height level of overflow water in municipality's sewer overflow chambers. More specifically, a video camera taking multiples pictures during the occurrence of an overflow with a large scaled ruler positioned beside the area of the overflow. Whereas the video information produced by said video apparatus is analyzed to provide the needed additional information to calculate with higher precision the volume of overflow water in sewer overflow chamber for a corresponding measured overflow water height level.
