摘要： A technique related to a fermentation process; where a signal processor receives a signal containing information about an amount of entrained air in a mixture forming part of a fermentation process in a tank; and determines a level of foam in the tank based at least partly on the amount of entrained air in the mixture. The signal processor may also provide a control signal for controlling an amount of defoamer (or antiforming agent) added to the mixture in the tank so as to control the production of foam within the tank by controlling the amount of defoamer added to the mixture in the tank.

摘要： Apparatus is provided having an acoustic-based air probe with an acoustic source configured to provide an acoustic signal into a mixture of concrete; and an acoustic receiver configured to be substantially co-planar with the acoustic source, to respond to the acoustic signal, and to provide signaling containing information about the acoustic signal injected into the mixture of concrete.

摘要： 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.
