Abstract
A system for calculating and reporting slump in a delivery vehicle having a mixing drum () and hydraulic drive () for rotating the mixing drum, including a rotational sensor () configured to sense a rotational speed of the mixing drum, a hydraulic sensor () coupled to the hydraulic drive and configured to sense a hydraulic pressure required to turn the mixing drum, and a communications port () configured to communicate a slump calculation to a status system () commonly used in the concrete industry, wherein the sensing of the rotational speed of the mixing drum is used to qualify a calculation of current slump based on the hydraulic pressure required to turn the mixing drum.
