Abstract
A system for calculating and reporting slump in a delivery vehicle having a mixing drumand hydraulic drivefor rotating the mixing drum, including a rotational sensorconfigured to sense a rotational speed of the mixing drum, a hydraulic sensorcoupled to the hydraulic drive and configured to sense a hydraulic pressure required to turn the mixing drum, and a communications portconfigured to communicate a slump calculation to a status systemcommonly 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.
