Working Principle

The sensor operates on the principle of component vibration. The component part is the tuning fork immersed in the liquid to be measured. The tuning fork part senses the vibration through an internal piezoelectric device fixed to the bottom end of the fork. The oscillation frequency is detected by a secondary piezoelectric device fixed to the other end of the fork, and then the signal is amplified by the circuit at the top.
The liquid concentration and the vibration frequency of the measured liquid during flow are closely related. When the concentration of the measured liquid changes, the vibration frequency of the liquid flow also changes. The concentration of the measured liquid can be accurately calculated using the following equation.
D = K0 + K1T + K2T2
D = Uncalibrated density of the measured medium (kg/m3)
T = Vibration frequency (μs).
K0, K1, K2 = Constants
