Techniques for sensing the volume and/or viscosity of concrete in a rotating container
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.

FLUID PROPERTY MEASUREMENT BY REFLECTION OF VIBRATIONAL WAVES
Systems and techniques are described making use of a vibratory transducer and a reflector spaced from the vibratory transducer to form a cavity for receiving a fluid between the vibratory transducer and the reflector, wherein the vibratory transducer is vibrated to generate a wave in the cavity, which propagates through fluid in the cavity from a surface of the vibratory transducer and is being reflected by the reflector to generate a counter-propagating wave in the cavity. Based on the wave generated at the vibratory transducer and the counter-propagating wave generated at the reflector in combination, an indication of the energy returned to the vibratory transducer by the reflector is determined. One or more material properties of the fluid are determined based on the determined indication of the energy returned to the vibratory transducer.

Ultrasonic time of flight flow measuring device and method
A method for operating a measuring device determining a fluid quantity relating to fluid or fluid flow uses a measuring tube receiving the fluid or conducting the flow and oscillation transducers spaced along the tube. A first flight time is recorded, then an ultrasound signal excited by a first transducer, after travel on a propagation path including only components of the measuring device to a second transducer, is recorded at a second transducer. A second flight time is recorded, then an ultrasound signal excited by the second transducer, after travel on the propagation path to the first transducer, is recorded at the first transducer. Then fulfillment of a report condition depending on a difference between flight times is checked. Upon fulfillment, a report is output to a user or a report message is sent to an external device or a correction parameter for determining the fluid quantity is adapted.
