PORTABLE CAVITOMETER

Designation

The cavitation meter is used to measure and regulate the cavitation activity inside powerful ultrasonic fields and hydrodynamic cavitators.

The system may be used for optimization of ultrasonic technological processes, for detection of the presence and intensity of cavitation in hydraulic systems, for measurements of cavitation thresholds.

Application

 

Industry:

  • - control and optimization of the operation procedures in suspension purification, infiltration and processing technologies, in particular, suspensions of nanoparticles; emulsification and emulsion processing, crystallization, degasifying treatment of liquids, etc..

 

Chemistry, sonochemistry:

- acceleration of sonochemical reactions;

- improvement of reactive ability in metallic surfaces;

- scission of high-molecular compounds (depolymerizing);

- catalytic effect in reactions with powders (for instance, catalytic effect of Nickel powder is intensified under ultrasound by several orders of magnitude);

- cracking processing of paraffins into smaller fragments under room temperature;

- increasing the yield rate in Ullmann and Wurtz reactions, as well as in other types of reactions.

 

Biology and medicine:

- enhancement of the membrane permeability in cells (sonoporation) without any serious impact on the cell life;

- inhibition of the cell growth and expansion;

- destruction of cells without the possibility of further recovery of functions.

Specialized sensors and cavitometers (cavitation meters), in particular, high-temperature and high-frequency ones can be produced on the technical specifications, provided by the Customer.

A high-temperature cavitometer (cavitation meter) makes it possible to measure the cavitation activity in liquid-alloys of metals under temperatures up to 1000 °.

A high-frequency cavitometer (cavitation meter) is used to measure the cavitation activity in ultrasonic fields with frequencies ranging from 0.5 up to 4 MHz.

Operation principle

The zone of cavitation (cavitation noise) generates an acoustic signal, which is received by the sensor incorporated into the system and converted into an electric signal. The latter is process by the electronic component, and the cavitation activity value is visible on the indicator.

The value obtained is the initial parameter needed to control and regulate the industrial processes or the extent to which the ultrasound affects the biological structures.

 

The physics of the cavitation measurement procedure is described here.

The following measurement modes are implemented in the basic model:

  • Full cavitation activity;
  • Transient cavitation activity.
