The basis of the measurement method is a time measurement that can be implemented very accurately and with long-term stability. From the sonic velocity, the concentration or density of a liquid is calculated. Other parameters can also be determined, such as the Brix content, solid content, dry mass, or suspension density.
Ultrasonic measuring devices have no mechanical parts that can wear out or age. They offer outstanding advantages over competing measurement methods.
The measurement method only requires precise time measurement. The sonic velocity is calculated from the transit time and the known distance between the transmitter and receiver. The typical sensor design includes the transmitter and receiver in a compact housing.
The measurement method is independent of the conductivity, color, and transparency of the liquid and is characterized by high reliability. The measurement accuracy of the devices is between 0.05 m% and 0.1 m%. In addition to sonic velocity measurement, all LiquiSonic® sensors have an integrated measurement of the process temperature.
