Measuring method of the LiquiSonic® system
The sonic velocity depends on density and on the compressibility of a material. The distance between the sonic transmitter and sonic receiver is known. The sonic velocity can easily be calculated by measuring the travel time of the sonic signal.With the sonic velocity the device calculates the concentration or density of the liquid. But other concentration values are also possible to measure, e.g. Brix, turbidity, conductivity, solid contents or gravity.
The electronics require a time measurement that can be realized digitally with outstanding accuracy and long time stability. Sonic velocity analyzers have no moving parts; therefore there is no long time degradation of their mechanical properties. Using this sensor technology, the user will have several advantages against competitive methods.
The sensor firmware calculates the sonic velocity by using the known distance between the transmitter and receiver.
The typical sensor design includes transmitter and receiver within one rough construction.
The method works without contact, regardless of color and transparency of the liquid and has excellent reliability. All sensors have an integrated temperature measurement. The user achieves a typical accuracy of 0.1% by weight.
Typical applications are:
- phase interface detection,
- multi-component analysis,
- monitoring of polymerization,
- crystallization processes.
