Abstract:
A system for monitoring fluid quality within a fluid flow in real time, is disclosed. The system comprises (a) a fluid filter incorporated into the fluid flow; the filter is adapted for filtering the fluid flow; (b) sensor means adapted for measuring a difference between an upstream pressure and a downstream pressure of the fluid flow; and (c) control means. The control means is adapted for estimating the fluid quality on a base of measuring a time period of rise in the pressure difference at the filter over a predetermined value.
