Abstract:
A sensing element for measuring a fluid composition comprising:an electrode base being disposed about an axis, said electrode base having an inner surface defining an aperture extending through the electrode base for allowing a fluid to flow therethrough; and a first electrode and a second electrode coupled to said electrode base and electrically isolated from one another, said first electrode having a first plurality of electrode teeth extending radially inwardly from said inner surface of the electrode base into said aperture, and said second electrode having a second plurality of electrode teeth extending radially inwardly from said inner surface into said aperture, said first plurality of electrode teeth being electrically connected together, and said second plurality of electrode teeth being electrically connected together, wherein said second plurality of electrode teeth are arranged in a substantially alternating pattern between said first plurality of electrode teeth to form a plurality of gaps between each of said first plurality of electrode teeth and said second plurality of electrode teeth, wherein electrical conduction through the fluid between said plurality of gaps is indicative of the composition of said fluid.
