A printed circuit board device includes: a first capacitive sensor configured to measure a first capacitance within a contained volume having known dimensions, wherein the first capacitance changes as a substance is received into the contained volume; a second capacitive sensor having a plurality of trigger points at a plurality of corresponding known heights within the contained volume, the second capacitive sensor configured to detect when the substance received into the contained volume has reached each of the corresponding known heights within the contained volume; and wherein at least one of a level of the substance within the contained volume, a volume of the substance within the contained volume, or a flow rate of the substance into the contained volume is determined based on data from the first capacitive sensor and the second capacitive sensor.

Capacitive measurement device with minimized sensitivity to manufacturing variability and environmental changes

A fluid analysis device including a fluid receipt chamber, a first capacitive element for measuring fluid flow into the fluid receipt chamber and a controller operatively coupled to the first capacitive element, wherein the controller is configured to measure a first capacitance of the first capacitive element.

Fluid analysis device and associated systems and methods

A substance measurement device includes: a container portion configured to receive a substance; a sensing device configured to measure a property of the substance related to at least one of a flow rate of the substance into the container portion, a level of the substance within the container portion, and a volume of the substance within the container portion; and at least one shield positioned within the container portion and configured to provide at least one of: a mechanical buffer between the substance entering the container portion and the sensing device; and an electrical shield between the substance entering the container portion and the sensing device.
