The application principle of online tuning fork density meter

A tuning fork density meter is a liquid density measurement device commonly used in pipelines, open or closed storage tanks, which can continuously and real-time monitor liquid density online. Its working principle is based on the correlation between the vibration of sensor components and the density of the medium. During operation, the tuning fork generates a fixed vibration frequency, and as the density of the measured liquid changes, the vibration frequency during liquid flow also changes accordingly. The density of the current medium can be calculated through circuit calculations.

Tuning fork densimeter is widely used, mainly in petrochemical industry, liquor making industry, food industry, pharmaceutical industry and mineral processing industry (such as coal slurry, syrup, starch lotion, lime slurry, etc.). It can achieve plug and play continuous and uninterrupted measurement without interrupting material flow. Due to its constant vibration during operation, there is no need to worry about the measured liquid sticking to the fork, ensuring the accuracy of the measurement results. In addition, it also offers a variety of material options, enabling effective detection even for corrosive media.
