Abstract

This article describes a vibroacoustic device for measuring the composition of the multicomponent liquid. The device operation is based on the property of resonance type construction such as changing the vibration parameters when changing the external acoustic load. Construction which allows to detail the parameters of the flowing liquid over the cross section of the measuring part of the device and the measuring technique which is based on tracking the amplitude-frequency response of the pre-selected mode shapes, which has showed persistence in different environments or their combinations are unique. The modal analysis is carried out and optimality criteria of mode shape of a sensor for this task are formulated. Researches of sensitivity of the design frequency are carried out.
