Vibrating Fork Density Meter in different density solution with different resonant frequencies, the resonance frequencies was different, according to the relationship of different vibration and density to calculate the density. The resonance frequency of the tuning fork density sensor is between 1600-2400. The higher the frequency the smaller density.
