Portable Tuning Fork Density Meter working principle

The tuning fork density/concentration meter is used to measure the density or concentration of liquid media. Density or concentration measurement is an important process control in the product manufacturing process.

Tuning fork densitometers can be used as indicators for other quality control parameters such as solids content or concentration values. It can meet various measurement requirements of users for density, concentration and solid content.

A tuning fork portable density meter that uses an acoustic frequency signal source to excite the metal fork. And make the fork vibrate freely at the center frequency. This frequency correlates with the density of the contacting liquid. Therefore, the density of the liquid can be measured by analyzing the frequency, and then the temperature compensation can eliminate the temperature drift of the system.

As for the concentration, the concentration value at a temperature of 20°C can be calculated according to the relationship between the corresponding liquid density and concentration.

This device integrates density, concentration and Baume into one. And has a variety of liquids to choose from.

Particle limit		Gas	Maximum Liquid Viscosity
Particle diameter	Suspended particles%
<10 microns	＜=40%	Generally do not use	＜1000cp
10~50 microns	＜=20%
