Official abstract text for this publication.
Systems and methods for determining a flow rate or volume of fluid. The system includes a positive displacement meter including a plurality of non-contact sensors and gears configured to rotate in response to fluid flow through the meter. The gears may include detectable areas that may be sensed by the plurality of non-contact sensors to determine a rotational direction of the gears. The plurality of non-contact sensors may also be configured to generate respective detection signals indicative of a rotation state of the gears. The controller may be configured to receive the detection signals, determine a current rotation state, and increment a rotational count based on the changes in the current rotation state. The controller may use the rotational count to determine a flow rate or volume of fluid.
Opening claim text (preview).
What is claimed is: 1. A system comprising: a flow meter having a housing that defines a chamber having a fluid inlet and a fluid outlet and having a first gear and a second gear installed within the chamber, the first gear intermeshing with the second gear so that the first gear and the second gear rotate together in response to fluid flow through the chamber, and at least one of the first gear and the second gear having a detectable area for detecting a rotational position of th…
