Fuel filter monitor for fuel streams

摘要

It has been discovered that the function of a fuel filter monitor can be accomplished without the use of SAP. The present invention provides a fuel filter monitor comprising an ePTFE membrane, a support structure adjacent to said ePTFE membrane wherein the membrane is disposed upstream of the support and said monitor prevents penetration of water to the downstream of said fuel wet monitor, where the water can be in the form of discrete water drops in the fuel, or a bulk water stream which displaces the upstream fuel.

主权项

1. A fuel filter monitor for use in a fuel stream having a flow direction comprising:
(a) a ePTFE membrane, wherein said ePTFE membrane has a Bubble Point >50 PSI; (b) a support structure adjacent to said ePTFE membrane; (c) said ePTFE membrane disposed upstream of said support structure in said fuel stream; (d) wherein said monitor prevents penetration of water to the downstream of said fuel wet monitor, where the water can be in the form of discrete water drops in fuel, or a bulk water stream which displaces the upstream fuel; (e) wherein said monitor stops fluid flow when challenged with a bulk water stream; and (f) wherein said monitor contains no super absorbent polymer for water.
