Patent ID: 7221279

Claim:
A sensor for use with an elimination-absorber monitoring system, said sensor comprising: sensing means and a flow-baffling layer disposed to divert direct flow of a liquid to be sensed around said flow-baffling layer prior to detection by said sensing means; a first liquid-permeable flow-conducting layer disposed adjacent said flow-baffling layer on the side of said flow-baffling layer opposite said sensing means, to collect and conduct a liquid to be sensed across said flow-baffling layer; and a second liquid-permeable flow-conducting layer, disposed opposite said first flow-conducting layer relative to said flow-baffling layer, to conduct liquid from said first flow-conducting layer, around said flow-baffling layer and toward said sensing means, wherein adjacent portions of said first and second liquid-permeable flow-conducting layers extend beyond an outer edge of said flow-baffling layer and are in fluid communication to conduct liquid around said flow-baffling layer and into said second flow-conducting layer.
