fluid flow total pressure, fluid flow measurement and airspeed measurement devices, and method for measuring total fluid flow pressure

摘要

A device is disclosed for measuring total pressure of a fluid flow comprising 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 transition chamber between the inlet chamber and the outlet chamber. Total pressure can be measured in the inlet chamber.
