DEVICE FOR MEASURING TOTAL PRESSURE OF FLUID FLOW

摘要

A device is disclosed for measuring total pressure of a fluid flow comprises a tubular member having an inlet chamber with an inlet opening at a first end of the tubular member. The tubular member also comprises an outlet chamber having an outlet opening at a second end of the tubular member. The inlet opening has a diameter transverse to the longitudinal axis and the outlet opening has a second diameter transverse to the longitudinal axis. The ratio of the first diameter to the second diameter is from 3:1 to 10:1. The tubular member also includes a transitional chamber between the inlet chamber and the outlet chamber. Total pressure can be measured in the inlet chamber.

1. A device for measuring total pressure of a fluid flow, comprising:
a tubular member having a central longitudinal axis, comprising
an inlet chamber having an inlet opening at a first end of the tubular member, the inlet opening having a first diameter transverse to the longitudinal axis,an outlet chamber having an outlet opening at a second end of the tubular member, the outlet opening having a second diameter transverse to the longitudinal axis, wherein the ratio of the first diameter to the second diameter is from 3:1 to 10:1, anda transitional chamber between the inlet chamber and the outlet chamber, the transitional chamber having a third diameter transverse to the longitudinal axis at an end toward the inlet chamber, and a fourth diameter, smaller than the third diameter, transverse to the longitudinal axis at an end toward the outlet chamber; and a total pressure sensor in communication with the inlet chamber.
