    Abstract: A method for determining condition of a highly resistive fluid in transportation and industrial equipment. The method uses apparatus that applies a high frequency oscillating voltage signals to electrodes immersed in the fluid and quantifies fluid response to the signals. Apparatus can further include means to control the temperature of the fluid, or a temperature sensor to monitor the temperature of fluid at the electrodes. The method monitors response of the fluid to the electrical signal applied by the apparatus. The frequency of the applied signal for the method is predetermined as a function of apparatus electrode geometry, fluid temperature or temperature range, and chemical composition of the fluid being monitored. The magnitude of fluid response relative to initial and the rate of change of the fluid response as a function of equipment use are used to essentially continuously determine fluid condition while in use. In particular, the method can determines approximate contaminant content of the fluid and can determine when the fluid has reached the end of its useful life due to the approximate contaminant content and/or due to loss or ability to disperse additional contaminants as very finely divided suspended particles. For apparatus or applications where the monitored fluid is not controlled to constant temperature, the method includes correcting the temperature sensitive fluid responses for temperature variations for the fluid quality and condition determination. The method can also include determining when essentially complete fluid exchanges are made to the equipment without need for additional input. ® KIPO & WIPO 2007
