Abstract:
A method for determining a property of a multiphase fluid, comprising the following steps:(a) directing the multiphase fluid through a first flow passage, wherein the first flow passage includes a first elbow for chancing the direction of the multiphase fluid;(b) monitoring the multiphase fluid with a first pressure transducer in communication with the first flow passage and positioned at the first elbow as the multiphase fluid passes through the first elbow, to obtain a first signal representing a variation in a first pressure as a function of time;(c) directing the multiphase fluid through a second flow passage, wherein the second flow passage includes a second elbow for changing the direction of the multiphase fluid and wherein the multiphase fluid passes through the first flow passage and the second flow passage in different directions relative to gravity;(d) monitoring the multiphase fluid with a second pressure transducer in communication with the second flow passage and positioned at the second elbow as the multiphase fluid passes through the second elbow, to obtain a second signal representing a variation in a second pressure as a function of time; and(e) determining the property of the multiphase fluid by comparing the first signal and the second signal with a set of calibration maps.
