Measuring principle
The density measurement is carried out according to the frequency oscillator principle.
Hereby a sample is filled into a swinging tube. The change in the oscillating frequency
following the changed oscillation mass enables the determination of the sample's density.
The following applies: r = A x T² + B
A and B are instrument constants of the oscillator.
A and B are determined through calibration.
A substance's density depends on the concentration
and the temperature.
