working principle

The Intelligent On-line Density uses the sound wave frequency signal source to excite the metal tuning fork, and makes the tuning fork vibrate freely at the center frequency. This frequency has a corresponding relationship with the density of the contact liquid, so the liquid can be measured by analyzing the frequency. Density, and temperature compensation can eliminate the temperature drift of the system; and the concentration can be calculated according to the relationship between the density and concentration of the corresponding liquid at a temperature of 25 ℃.
