1. A system for calculating and reporting slump in a delivery vehicle having a mixing drum and hydraulic drive for rotating the mixing drum, comprising:

  • a rotational sensor mounted to the mixing drum and 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 processor computing a slump value using the sensors, 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.
