Originální abstrakt
The paper is concerned on a new mass method of measurement of small flow of two-phase media, where the solid particles are carried by a carrying gas (air). The method exploits the fact that the solid particles being carried by a flowing air impacting a properly formed obstacle generates an acoustic surface wave (acoustic emission). The acoustic signal is indicated by the aid of a high sensitive transducer, which converts the acoustic signal to an electric one. The magnitude of the electric signal is proportional to the (average) mass of particles having a constant (unified) velocity. In general, this way we get the information about the magnitude of particles being measured and about their quantity. The electric output signal of the transducer is processed in the electric section of the meter, using up-to-date electrical devices being able to carry out amplitude or frequency analyses of the signal and performs its another processing.
