Velocity-enhanced flow measurement |
摘要 |
A process fluid flow measurement device includes a fluid flow member having an inlet with a first diameter and a throat with a second diameter that is smaller than the first diameter. A first process fluid pressure tap is disposed proximate the inlet and a second process fluid pressure tap is disposed proximate the throat. A differential pressure sensor is operably coupled to the first and second process fluid pressure taps. Differential pressure measurement circuitry is coupled to the differential pressure sensor to provide a differential pressure signal related to a difference in pressure between process fluid pressure at the first and second taps. A process fluid velocity measurement device is positioned in the throat to measure a velocity of process fluid flowing therethrough and provide a fluid velocity indication. The differential pressure sensor signal and the fluid velocity indication are used to provide a calculated indication of fluid flow. This calculated indication can be relative to multiphasic fluids such as two-phase or three-phase fluids.
