US 2022/0178806 A1 · TECHNIQUES FOR SENSING THE VISCOSITY OF CONCRETE IN A ROTATING CONTAINER

Abstract

A system for sensing the volume and/or viscosity of a slurry (e.g., like concrete) contained in a rotating container or drum, having a sensor and a signal processor. The sensor is configured to attach inside a rotating container or drum having a known geometry, sense angular positions of the sensor and also sense associated entry and exit points when the sensor enters and exits the slurry, including concrete, contained in the rotating container or drum, and provide signaling containing information about the angular positions and the associated entry and exit points. The signal processor receives the signaling, and determines corresponding signaling containing information about a volumetric amount, or a viscosity, or both, of the slurry in the rotating container or drum, based upon the signaling received.

A system for sensing the viscosity of concrete in a rotating container or drum, comprising:

a sensor configured to attach inside a rotating container or drum having a known geometry, sense angular positions of the sensor and sense associated entry and exit points when the sensor enters and exits concrete contained in the rotating container or drum, and provide signaling containing information about the angular positions and the associated entry and exit points;
and
a signal processor configured to
receive the signaling,
determine an amount of “tilt” of the concrete in the rotating container or drum based upon the angular positions and the associated entry and exit points when the sensor enters and exits concrete contained in the rotating container or drum;
receive further signaling containing information about the known geometry;
and
determine corresponding signaling containing information about a viscosity of the concrete the rotating container or drum, based upon the signaling and the further signaling received.
