Density Meter DS7000 – How it works

Density measurement with a u-tube oscillator

- The sample is filled into the u-tube oscillator which is electronically excited to vibrate at its natural frequency

- The resonant frequency of the u-tube oscillator changes as a function of the density of the filled sample

The ratio of density to resonant frequency examplified with air and water

- The density is determined by measuring the resonant frequency that occurs

- Roughly speaking, the greater the density / mass of the sample, the lower the frequency

- The measuring cell is tempered with high precision to ensure a highly accurate measurement
