Originální abstrakt

Cross correlation flowmeters with piezoelectric acoustic emission sensor are described. The new type of sensing elements exploits the fact that the solid particles being carried by a flowing air and impacting a properly formed obstacle generate an acoustic surface wave (acoustic emission - AE). The acoustic signal is indicated with the help of a high sensitive transducer, which converts the acoustic signal to an electric one. If we use two sensing elements in the flow channel with defined distance, we may use cross correlation technique to calculate transit time. From the time and distance of the obstacles the speed of particles may be calculated. Examples of measured data and method of data processing is presented.
