Abstract: A fluid sensor arrangement (20) includes a sleeve (32) that is adapted to be placed within a container (24). A plurality of conductors (46, 48) and a channel member (50) within the sleeve cooperate to provide a measurement of conductivity of the fluid within the sleeve (32). The conductivity measurement provides an indication of a level of fluid within the container (24). A disclosed example includes a non-conductive channel member (50) having an opening or a channel (52) for directing selected portions of a conductivity field within the sleeve (32) between the conductors (46, 48) for making the conductivity determinations.

Abstract: A sensor (40) includes a single capacitor (42) that operates in two different modes to obtain capacitance and conductance information when a mixture flows between the electrodes (44, 46) of the capacitor. The inventive sensor is particularly well-suited for making methanol content determinations within a mixture used to provide hydrogen to supply a fuel cell. Two different oscillators (180, 182) are selectively used to obtain the conductance and capacitance information. In a disclosed embodiment, a capacitor includes an outer electrode (44) that is received around an inner electrode (46) such that there is a spacing between the electrodes through which the mixture flows. The mixture acts as a dielectric of the capacitor allowing the conductance and capacitance measurements to be made. The example sensor includes a temperature sensor (76) conveniently supported within the inner electrode (46).

Abstract: A sensor device (10) for making at least one determination regarding a selected characteristic of a fluid includes a support post (32) that is adapted to be exposed to the fluid. A capacitor has electrodes (66, 68) that are supported near one end of the support post (32). A housing (40) for containing electronics (120) is supported near an opposite end of the support post (32). In a disclosed arrangement, a level sensing element such as a conductive polymer rod is at least partially supported by the support post (32). A disclosed assembly procedure includes overmolding portions of the device onto other portions to provide stable and secure connections between the various portions of the assembly.
