Abstract
A flow gauge scale assembly includes a first scale and a second scale. The first scale is configured to be disposed in a first radial position on a generally cylindrical flow tube through which a ball can move to indicate a flow rate of a flow of gas. The second scale is configured to be disposed in a second radial position that will be at least partially optically misaligned from the first scale when the flow gauge scale assembly is installed in the generally cylindrical flow tube.
Claims20
A flow gauge comprising:
- a generally cylindrical flow tube that extends from a first end to a second end, the first end being fluidly coupled to a flow path through a regulator or flowmeter;
- a ball that is movable within the generally cylindrical flow tube in response to a flow of gas moving along the flow path;
- a first scale disposed on the generally cylindrical flow tube;
- and
- a second scale disposed on the generally cylindrical flow tube in a position that is at least partially optically out of phase from the first scale, wherein the first scale and the second scale are offset with respect to a radial zone of the generally cylindrical flow tube such that an axis extends through the first scale, a centroid of a cross-section of the generally cylindrical flow tube taken along a plane defined by radii of the generally cylindrical flow tube, and the radial zone, the radial zone is devoid of any markings, and the radial zone is transparent.

- and
- a second scale configured to be disposed in a second radial position that will be at least partially optically misaligned from the first scale in an installed configuration of the flow gauge scale assembly in the generally cylindrical flow tube, wherein the first scale and the second scale are offset with respect to a radial zone of the generally cylindrical flow tube such that an axis extends through the first scale, a center of a cross-section of the generally cylindrical flow tube taken along a plane defined by radii of the generally cylindrical flow tube, and the radial zone, wherein the radial zone lacks any markings, and wherein the radial zone is transparent.
