NYDE - CR Tuning Fork Densitometer For Tank Pipe Density Measurement

Easy To Install And Use Tank And Pipe Density Measurement NYDE-CR Tuning Fork Densitometer

NYYC-MD type insertion densitometer can be used for real-time online density detection. It can be used in the process control of products with density as the basic parameter or quality control with solid percentage or concentration percentage as the reference. Using the insertion type installation, widely used in pipelines, open tank containers and closed tank containers in the media density detection fluid density depends directly on the vibration frequency received by the tuning fork inserted into the medium. Sensor built-in temperature sensor to provide temperature compensation. Widely used in petroleum, chemical, brewing, food, pharmaceutical and mineral processing (such as clay, carbonate, silicate, etc.), specific applications in the above industries in the multi-product pipeline interface detection, stirring mixture density detection, reactor endpoint monitoring, ionizer interface detection.

NYDE-CR Tuning Fork Densitometer Working Principle

The sensor works on the principle of component vibration, the component part being the tuning fork part immersed in the measured liquid. The tuning fork part senses the vibrations through an intrinsic piezoelectric device fixed at the bottom end of the fork body. The vibration frequency is detected by a secondary piezoelectric device fixed at the other end of the fork, and then the signal is amplified by a circuit at the top. The density of the liquid and the frequency of vibration when the measured liquid flows are closely related, and when the density of the measured liquid changes, the frequency of vibration when the liquid flows also changes. Through the equation D=Ko+KIT+KETz, the density of the measured liquid can be calculated accurately.

D = density of the measured medium without calibration (kg/m³)

T = frequency of vibration (μs).

Ko, Ki, K2 = constants

In the density detection process, NYYC-MD plug-in densitometer can automatically compensate for the effect of temperature on the density of the measured medium (D), and the pressure has no significant effect on the density.
