<p>The invention provides an apparatus and method for monitoring the volume of material loaded into a truck body. Apparatus is provided for sensing the volume of material held in the truck body and indicating, visually or audibly, when a predetermined volumetric loading has been accomplished. Such an indication informs the appropriate personnel that, if the material being loaded is of high density, loading should be stopped. Several different embodiments for the sensing apparatus are disclosed, one of which is a plurality of horizontal holes in the side of the truck body located at a level corresponding to the maximum loading level for a high density material. A cover plate is provided for covering these holes when not being used as a horizontal sight gauge for monitoring the volume level of the material being loaded. Each of the plurality of holes includes a mechanism for preventing material flow through the holes when the cover plate is lowered to expose them to view for use as a horizontal sight gauge.</p> |
