Estimating the term…
An electrical property sensor for a low-conductivity fluid that includes a laminated structure including a conductive layer, an insulating layer, and a conductive trace, the laminated structure having a first face separated from a second face by a thickness, the first face having a length and a width. The sensor includes a first and second aperture, each of the first and second apertures extending from a first face of the laminated structure to a second face of the laminated structure, the first and second aperture each include a receiving electrode and a transmitting electrode. When a fluid flows through the first aperture and an electric field is generated, an electrical property signal is received for the low-conductivity fluid.
An electrical property sensor for a low-conductivity fluid, the sensor comprising:
The sensor of claim 3, wherein the first aperture has a first distance from an edge connector of the laminated structure, wherein the second aperture is parallel to the first aperture, and wherein a second center of the second aperture has a similar distance from the edge connector as a first center of the first aperture.
The sensor of claim 4, wherein the second aperture is parallel to the first aperture and wherein the second aperture is at a second length from an edge connector, different from a first length of the first aperture from the edge connector.
A dispensable mixture kit, the kit comprising:
20-30. (canceled)
A method of detecting an inconsistency in a low-conductivity fluid, the method comprising:
32-40. (canceled)
