ABSTRACT:
A sensor which is installed in a waste tank to determine when the tank is full includes a shroud having a body with a curved surface and a leading edge which is mounted flushly to the inner surface of the tank wall and a trailing edge which is spaced apart from the sensor face. As waste material is swirled about the inside surface of the tank wall, the shroud causes the waste material to be transported above the sensor face without disrupting the flow of the waste material along the tank wall. The cover is sized and configured appropriately to allow convenient rinsing when the waste tank is emptied.
