Abstract
The invention relates to a method for determining the density of a fluid medium with a bending oscillator, the oscillator tube of which is flowed through by the measuring fluid. According to the invention, it is provided to use the period of the oscillation of the free and damped oscillating oscillator tube for density determination. For this purpose, the excitation of the exciter amplifier is alternately interrupted by means of a switch and switched back into the resonant circuit. The period of the damped oscillation is used together with its amplitude and or phase position for the output of a viscosity-corrected density.
