Abstract
A system for measuring the height of paving material distributed by an auger of a paving machine in front of a grading implement, such as a screed, is disclosed. The system includes a sonic sensor and a laser pointer. The sonic sensor generates a sonic signal which is directed at the paving material distributed by the auger. The laser pointer generates a laser beam which is similarly directed at the paving material that has been distributed by the auger. The laser beam and the sonic signal meet at a common position on the paving material.
