Rotary concrete volume determination

A method is disclosed for determining the volume of concrete mix load in a mixer drum based on the use of entry and exit sensor probes that are submerged into and exit from concrete during drum rotation and providing data to a processor for calculating the volume based on the data. To provide concavo, convexity, and/or cascade surface flow effects that may hinder accurate determination of concrete load volume, the processor may be configured to compare rheology of concrete load and/or original batch volume monitored during drum rotation. Calibration of load volume values, which is very useful for monitoring or admixture dose purposes, may be done based on comparing real-time data to historical data collected over time and stored in processor-accessible memory. Additional exemplary embodiments also take into account the speed and/or inclination of the drum (due to road conditions), concrete mix design, and other factors. 公开了一种用于基于进入和离开传感器探头的使用来确定搅拌机筒中的混凝土混合料荷载的体积的方法，所述传感器探头在筒旋转期间浸没到混凝土中以及从混凝土中离开，并且向用于基于所述数据来计算
