Abstract

A method for temperature compensating data relevant to the quality and/or condition of a fluid in use in transportation and industrial devices and/or processes. The method includes collecting and determining the temperature dependence of fluid quality and/or condition relevant data from a first fluid threshold temperature to at least a second fluid threshold temperature when change of fluid temperature is equal or greater than a preset rate, and using the determined dependence to compensate the relevant data to a standard temperature while the fluid is in use.

Claims

1. A method to temperature compensate data of a fluid while in use that comprises:

a) collecting data when fluid temperature changes from a first threshold temperature to at least a second threshold temperature at least at a threshold rate;

b) determining the temperature dependence of the collected data; and

,

c) using the determined data-temperature-dependence for temperature compensating data of the fluid'"'"'s condition.

5. The method of claim 1 wherein the method further comprises determining at least one of the following selected from the group consisting of:

threshold temperature, threshold rate or combinations thereof.

12. The method of claim 1 wherein a property of the determined data-temperature-dependence not being within at least one property is selected from the group consisting of:

the determined data-temperature-dependence alone;

a function of the determined data-temperature-dependence and the current data-temperature-dependence and combinations thereof.
