TFD-620 High-temperature Tuning Fork Densitometer

The resonant fork density meter operates based on the principle of component vibration. The component part is the fork portion that immerses into the measured liquid. The fork part induces vibration by the built-in piezoelectric device fixed at one end of the fork body. The oscillation frequency is detected by the secondary piezoelectric device fixed at the other end of the fork body and then amplified through the circuit on the top. Liquid density is closely related to the vibration frequency when the measured liquid flows. When the density of the measured liquid changes, the vibration frequency during liquid flow also changes accordingly. The density of the measured liquid can be accurately calculated through the following equation:

D= K0+K1T+K2T2

D= density of uncalibrated measured medium (KG/M3)

T= perturbation frequency (MS).

K0, K1, K2= constants
