Abstract: A method for determining a fuel-dilution condition of a lubricant used in transportation and industrial equipment. The method uses apparatus that applies a high frequency and optionally a low frequency oscillating signal to electrodes immersed in the fluid and quantifies fluid response to the signals. Apparatus can further include means to control the lubricant temperature, or a temperature sensor to monitor the lubricant temperature at the electrodes. The method monitors response of the lubricant to the applied electrical signals and determines ratios of lubricant properties. The high-frequency lubricant property ratio or change of high frequency lubricant property as a function of a lubricant use-measure is compared to a predicted ratio based on lubricant use and an estimate of the lubricant's fuel dilution determined. The optional low-frequency lubricant property ratio is compared to thresholds to determine when the lubricant loses the ability to control fuel dilution. The method outputs information relevant to the fuel-dilution condition of the lubricant.

Abstract: A method for determining condition of a highly resistive fluid in transportation and industrial equipment. The method is suitable for determining the condition of a non-aqueous fluid including applying a high-frequency voltage signal between electrodes immersed in the fluid, measuring the fluid's response to the applied signal and determining a fluid property, and comparing the magnitude of the determined property, relative to the magnitude of that that property when the fluid is fresh.

Abstract: A method for determining quality and condition of a highly resistive fluid in transportation and industrial equipment. The method uses apparatus that applies a multitude of oscillating voltage signals at determined frequencies and offsets to electrodes immersed in the fluid and quantifies fluid response to the signals. The method monitors response of the fluid to a preferred three fixed electrical signals applied by the apparatus, a high and a medium frequency signal with zero offset voltage and a low frequency signal with an offset voltage. 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.

Abstract: An apparatus and method for monitoring a highly electrically-resistive fluid. The method includes applying across the fluid an AC signal that includes at least two different AC electrical potentials, with at least one AC electrical potential having a non-zero DC offset, measuring the fluid's electrical response at each applied potential, and analyzing the fluid quality and/or condition using the applied AC signal and the corresponding measured electrical responses. The invention finds application in conjunction with the on-line (i.e., while in use) monitoring a highly resistive fluids such as, e.g., lubricants, natural and/or synthetic motor oils optionally including standard additives and/or adjuncts, combustion engine fuels, other hydrocarbon-based fluids used in transportation and industrial applications, and the like.

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.
