Concentration and density measurement

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



Typical applications

  • concentration monitoring and blending



  • limit value monitoring
