Abstract: The invention provides a signal processor that receives a signal containing information about an acoustic signal that is generated by at least one acoustic transmitter, that travels through an aerated fluid in a container, and that is received by at least one acoustic receiver arranged in relation to the container, including inside the container; and determines the gas volume fraction of the aerated fluid based at least partly on the speed of sound measurement of the acoustic signal that travels through the aerated fluid in the container. The signal processor also sends an output signal containing information about the gas volume fraction of the aerated fluid. The signal processor may be configured together with at least one acoustic transmitter, the at least one acoustic receiver, or both.

Abstract: A method for determining one or more fluid flow parameters for a fluid flowing within a pipe is provided. The fluid is a mixture of solid particles and gas. The method includes the steps of: a) providing a meter operable to determine the velocity of the fluid flow through the pipe, which meter is substantially insensitive to the particulate/gas mass ratio of the fluid flow; b) determining the velocity of the fluid flow within the pipe using the meter; and c) determining a particulate/gas mass ratio using a density value for the gas within the flow and the determined fluid flow velocity.

Abstract: A system features a combination of an acoustic sensor and a communication transmitter. The acoustic sensor is arranged on a rotating container or drum having a slurry contained therein, including concrete, and configured to provide an acoustic signal to sense an acoustic signal containing information about a characteristic of the slurry, and provide acoustic sensor signaling containing information about the acoustic signal sensed. The communication transmitter is arranged on the rotating container or drum, and configured to receive the acoustic signal, and provide the acoustic signal received from the rotating container or drum for further processing.

Abstract: The present invention provides a new and unique apparatus featuring a signal processor or processing module configured to: receive signaling containing information about a fluid flow passing through a pipe that is channelized causing flow variations in the fluid flow; and determine corresponding signaling containing information about a fluid flow characteristic of the fluid flow that depends on the flow variations caused in the fluid flow channelized, based upon the signaling received. The signal processor or processing module may be configured to provide the corresponding signaling, including where the corresponding signaling contains information about the fluid flow characteristic of the fluid flow channelized.
