The liquid motion control device has a control unit with an acoustic resonator (30) that is positioned in the path of SAW, and having a resonance cavity (30) between a pair of acoustic reflectors (31a,31b), which is arranged consecutively with respect to one another in the propagation direction of SAW. The acoustic resonator normally allows transmission of SAW having frequency equal to resonance frequency, and reflects SAW when quantity of liquid is present within the acoustic resonator.

Abstract
The liquid motion control device has a control unit with an acoustic resonator (30) that is positioned in the path of SAW, and having a resonance cavity (30) between a pair of acoustic reflectors (31a,31b), which is arranged consecutively with respect to one another in the propagation direction of SAW. The acoustic resonator normally allows transmission of SAW having frequency equal to resonance frequency, and reflects SAW when quantity of liquid is present within the acoustic resonator.File in questo prodotto:
