Abstract
A method and apparatus for detecting a fouled fluid filter are disclosed in which the fluid pressure at the outlet of the fluid filter is corrected by a correction pressure to determine a corrected pressure drop. Such a corrected pressure drop has a mathematical function which passes through a maximum magnitude before the fluid flowing through the fluid filter reaches a maximum value. The corrected pressure drop is monitored during the operation of the fluid filter and when the corrected pressure drop reaches a predetermined threshold value, before the engine with which the fluid filter is associated reaches its maximum power, an alarm will be actuated.
