Method of determining a fill level of an oscillator of an oscillator tube, and oscillator tube

Abstract

A method determines a degree of filling of an oscillator tube of a frequency oscillator with a fluid to be examined, in particular related to the density measurement of fluids with the frequency oscillator. By adjustment or calibration standards for the fluid to be examined, or for fluids possessing various viscosities, the relationship between the damping and/or oscillation amplitude of the frequency oscillator and the degree of filling of the oscillator tube is determined. In the course of determining the degree of filling, a parameter relevant for the damping and/or oscillation amplitude of the frequency oscillator is measured, and the measured value is considered as relevant and functionally related to the degree of filling and can be used for evaluating or determining the degree of filling.
