Angled port differential pressure flow meter

摘要

An aspect provides a flow metering apparatus, comprising: a fluid conduit having a differential pressure producer therein; at least one pressure port angled between 0 and 90 degrees in a wall of the fluid conduit; and at least one other pressure port; wherein the at least one pressure port and the at least one other pressure port provide pressure signals. Other aspects are described and claimed.

1. A flow metering apparatus, comprising:
a fluid conduit having a cone shaped differential pressure producer therein; a support member securing the cone shaped differential pressure producer to a wall of the fluid conduit; at least one angled pressure port in a wall of the fluid conduit; the at least one angled pressure port being angled downstream of the cone shaped differential pressure producer; the angle of the of the at least one angled pressure port being selected such that the centerline of the at least one angled pressure port extends across the flow in a relatively undisturbed region; and at least one other pressure port; wherein the at least one angled pressure port and the at least one other pressure port provide pressure signals.
