Abstract:
1. A system for monitoring the operation of a vacuum loader truck including a storage tank and a vacuum source in fluid communication with the storage tank, wherein the vacuum source operates to create a partial vacuum within the storage tank to draw debris into the storage tank, the system comprising: a debris level sensor mounted at a top end of the storage tank, wherein the debris level sensor generates a sensing beam downward toward a bottom end of the storage tank to sense a distance to a top surface of the debris in the storage tank; a control module connected to the debris level sensor to receive a signal from the debris level sensor and determine a level of debris in the storage tank, wherein the control module generates an output signal to a visual display that visually indicates the determined level of debris in the storage tank; and a flushing device positioned to direct a flow of water onto the debris level sensor to clear the debris level sensor, wherein the flushing device is in communication with the control module.
