Abstract
A method and system for contact potential sensing of dielectric properties of a fluid. The method and system include a contact potential sensor, an open or closed loop for passing a fluid past the sensor, measuring a contact potential to characterize dielectric properties of the fluid and outputting the dielectric property information for analysis and response thereto.
Claims20
A method of monitoring chemical changes of a fluid, comprising the steps of:
- providing a contact potential difference sensor;
- flowing a fluid past the sensor to generate a contact potential;
- and
- characterizing the contact potential as a measure of chemical changes of the fluid.
