Device and method for weighing solid waste with an angle-correction scale

A device (10) for correcting for the out-of-level condition of a weighing apparatus (20), which includes a scale (22) and a clinometer (24) to provide an accurate weight measurement of a load disposed thereon whenever the tilt of the scale (22) is within preselected out-of-level angles. The device (10) is configured such that the scale (22) and the clinometer (24) provide respective analog weight (23) and angle (60) signals to an analog-to-digital ratiometric converter (70) which generates a proportional digital output signal (72) to a microcomputer (40) for storing the weight in memory (42) and visually displaying the weight on a weight display (48). The device (10) also provides a method for correcting the angle of a weighing apparatus (20) which includes providing a vehicle (12) with a scale (22) mounted thereon, monitoring the weight of any object disposed on the scale (22) and providing a weight signal (23) proportional thereto, monitoring the angle of the scale (22) and providing an angle signal (60) proportional thereto, conditioning the angle signal (60), converting the weight signal (23) and angle signal (60) to an output signal (72), and displaying and storing the output signal (72).
