US 2026/0298694 A1 · MULTIPHASE FLOWMETER (MPFM) LIQUID REFERENCING VEHICLE

Abstract

A multiphase flowmeter (MPFM) liquid referencing vehicle having a portable multiphase flowmeter (MPFM). A multiphase flowmeter (MPFM) coupled to a pipeline may be calibrating using the portable multiphase flowmeter (MPFM) and without opening the upper flange coupled to the multiphase flowmeter (MPFM). The nuclear energy rate from the multiphase flowmeter (MPFM) may be measured and compared to a threshold decay margin. If the nuclear energy rate is below the threshold decay margin, the multiphase flowmeter (MPFM) liquid referencing vehicle may be used to calibrate the multiphase flowmeter (MPFM).

Dependent claims

A method for calibrating a multiphase flowmeter coupled to a pipeline, comprising:

isolating the multiphase flowmeter from an inlet and an outlet;
opening a drain valve to remove liquid in a Venturi section of the multiphase flowmeter;
initiating an empty pipe calibration for a time period;
measuring a nuclear energy rate generated from a radiation source in the multiphase flowmeter over the time period;
determining that the nuclear energy rate is within an error range as compared to a previous empty pipe reference measurement;
and
using a portable multiphase flowmeter located in a vehicle to calibrate the multiphase flowmeter without opening an upper flange connected to the multiphase flowmeter.
