Abstract
The present embodiments provide methods, apparatuses, and systems for use in measuring volume of fluid flow and/or pressures. Some embodiments providing apparatuses for use in measuring pressures include a manometer comprising a conduit with a curved portion that is substantially half parabolic in shape. A pattern of markings is spaced along the curved portion of the conduit, and a displacement fluid is maintained within the conduit such that the displacement fluid is forced along at least a portion of the curved portion of the conduit when the manometer is subject to a pressure difference.

An apparatus for use in measuring pressure, comprising:
- a manometer comprising a conduit having a curved portion that is substantially half parabolic in shape;
- a pattern of markings spaced along the curved portion of the conduit;
- and
- a displacement fluid maintained within the conduit that is forced along at least a portion of the curved portion of the conduit when the manometer is subject to a pressure difference.
An apparatus for use in measuring fluid flow, comprising:
- a manometer comprising a conduit having a curved portion;
- a pattern of markings substantially linearly spaced along at least a portion of the curved portion of the conduit;
- and
- a displacement fluid maintained within the conduit that is forced along at least a portion of the curved portion of the conduit when the manometer is subject to a pressure difference.
A method for use in calibrating a scale of a manometer, the method comprising:
- positioning a pattern of markings on the curved portion of the conduit;
- directing a flow of fluid at a plurality of different flow rates to pass through a first orifice;
- measuring a pressure difference across the first orifice for each of the plurality of different flow rates;
- comparing the measurements across the first orifice with reference pressure differences;
- determining an accuracy of the pattern of markings relative to results of the comparison of the measurements;
- and
- adjusting at least a range of the markings on the curved portion of the conduit when a difference the accuracy of the pattern of markings in at least the range of markings has at least a predetermined relationship with respect to an accuracy threshold.
