On the project

Description in English
The project 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 the flowing air impact aproperly formed obstacle and an acoustic wave rises (acoustic emission in ultrasonic range). 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 electricsignal 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 possible to carry out amplitude or frequency analyses of the signal and its another processing. Powder technologies are the main area where this technology
