Spool Piece Multiphase Flow Meter

Introduction

The SP (Spool Piece) MPFM is a state-of-the-art technology for inline measurement of multiphase flow. The meter allows for accurate measurement of oil, water and gas flow rates, with a very compact mechanical solution. Depending upon requirement, the meter can either be a spool piece or a skid mounted design.

Working Principle

1. This compact unit is composed of a Venturi flow meter and dual gamma meter.

2. Total Flow Rate of the multiphase fluids (TFR) is measured by venturi flow meter.

3. Multi-Variable Transmitter (MVT) measures the differential pressure across the venturi along with temperature and pressure. The raw signals from the MVT are processed by the Data Acquisition Unit, and then used to calculate the total flow rate along with PVT parameters.

4. The Dual Gamma Meter is used to measure GVF and WLR of the multiphase fluids. The pulses from the dual gamma detector are collected and processed by the updated Sitan high speed dual gamma transmitter to provide high water cut accuracy at 0~95% GVF level.

The volumetric flow rates at standard conditions are computed from flow rates at line conditions using PVT software model . The PVT model developed by Sitan is a versatile tool for characterizing multi-component mixtures with emphasis on reservoir fluids.
