Abstract

Crude oil is a mixture of gas, oil and water. Knowing the ratio of these three components can help to optimize the production process. Multiphase flowmeters have therefore been designed and constructed in recent years. However, the costs of current multiphase flowmeters based on radiation techniques are too expensive. In order to overcome this drawback, a low-cost electrical impedance-based multiphase flowmeter is investigated in the research. -- After numerical simulations and experiments, this thesis develops a DSP-based impedance measuring instrument that can obtain the impedance data from crude oil in real time. Experimental data show that the performance of this DSP-based impedance measuring instrument has good resolution and good linearity. -- The work completed to date acts as a starting point from which improvements and extensions can be easily made and incorporated. In this regard, suggestions for future work are also presented.
