Abstract

The analysis of self-oscillatory system of the mechanical resonator of a liquid densimeter consisting of the magnetoelectric exciter, parametric capacitor receiver, and the nonlinear amplifier is performed. The generalized transfer function of the resonator, transfer functions of the exciter and the receiver are obtained. Conditions of stability are investigated. Measurement errors are estimated.
