Abstract
Methods and systems are provided for measuring pressure drop through a filter in the flow path and then using the measured pressure drop, possibly at a normalized state and in conjunction with time and/or other data from the system, to estimate characteristics of the fluid, the filter, and/or a working component supplied with the filtered fluid. Such characteristics could include an operating condition of the filter, the remaining useful life of the filter, the relative contaminant concentration in the fluid, and/or the remaining useful life of a working component supplied with the filtered fluid.
