Patent ID: 6855249

Claim:
A filtration health monitoring system comprising: a filter module including a filter element, said filter element having an inlet side, an outlet side, and a membrane separating said inlet side from said outlet side such that there exists a differential pressure across said membrane when said filter element is in service; a first micro-electro-mechanical systems (MEMS) pressure sensor disposed proximate said inlet side for measuring a first pressure on the inlet side; a second MEMS pressure sensor disposed proximate said outlet side for measuring a second pressure on the outlet side; and a processing device, said device being configured to: receive measurement data from said first and second MEMS pressure sensors; calculate the differential pressure across said membrane based on said measurement data; calculate a remaining contaminant capacity of the filter element based on a correlation of said differential pressure to an amount of contaminant removed by said filter element; calculate a rate of contaminant removal; and determine the remaining service life of said filter element.
