Abstract
A system and method for determining pressure differences of a fluid flowing through a differential pressure conduit positioned in a wellbore. The system comprises a first pressure measurement circuit positioned at a first pressure measuring station and including a first pressure sensor to generate a first pressure measurement signal indicative of the pressure measured by the first pressure sensor at a first signal point, and a second pressure measurement circuit positioned at a second pressure measuring station and including a second pressure sensor to generate a second pressure measurement signal indicative of the pressure measured by the second pressure sensor at a second signal point. The calculation of the pressure differential between the first and second pressure measuring stations is based on the first and second pressure measurement signals taken or read from the first and second signal points, wherein the first and third second points are symmetrical.
