Concentration and Density Measurement

The ultrasonic analyzer LiquiSonic measures the concentration and density of liquids. In a typical application, the device measures the sound velocity and compares it to a calibration curve to generate a concentration value.

Typical Applications

 

Concentration monitoring and blending

 

Limit value monitoring
