The Ultrasonic Density Meter/Concentration Meter utilizes the principle of ultrasonic sound velocity measurement and integrates multiple detection technologies for online, precise measurement of solution concentration, density, solid content, and Brix value.
Ultrasonic detection is unaffected by the turbidity, color, and conductivity of the medium, nor is it affected by flow conditions or impurities. The built-in high-precision resistance temperature detector and reliable sensor design ensure real-time, accurate measurements.

Ultrasonic Density Meter/Concentration Meter Measurement Principle
An ultrasonic transmitting probe emits a beam of ultrasonic signals. The signal travels through a liquid of a certain concentration and reaches another ultrasonic receiving probe on the opposite side. The total transmission time of the ultrasonic signal is measured, and the distance divided by the time gives the ultrasonic sound velocity.
Within a certain concentration or density range, the propagation speed (v) of the ultrasonic signal in the liquid medium is a function of concentration or density (c) and temperature (t), as shown in the figure.
The above figure shows the sound velocity-concentration dependence for 10-100 wt% alcohol.
When several media with different sound velocities are mixed, there is a definite relationship between sound velocity and concentration. After calibration and temperature compensation, the ultrasonic concentration and density analyzer can accurately measure the concentration of multi-component liquid media.
Based on the same principle, sound velocity and density are also highly correlated, thus allowing for accurate measurement of the density of single-component or multi-component liquid media.

More Density-Concentration Meters
The ultrasonic density meter/concentration meter measures liquid concentration using the ultrasonic sound velocity method. This is based on the principle that the speed of sound through a liquid varies with concentration and temperature. Each liquid is tested individually to create a unique sound velocity data model with temperature compensation. Combined with a unique algorithm, the instrument offers high measurement accuracy and excellent long-term stability.
