Ultrasonic Flow Meter

The bubbles in the liquid will scatter and absorb the ultrasound, therefore the existence of bubbles will seriously affect the ultrasound propagation in the liquid medium inside the pipeline. This paper analyzes the influence of bubbles in the liquid on the performance of the ultrasonic flow meter, and the gas-liquid two-phase flow rate measurement experiments are implemented. Experimental results show that with the increase of the bubble volume fraction in the liquid, the measurement error of the ultrasonic flow meter increases. When the bubble volume fraction exceeds 1%, the transit-time difference method of measuring the flow rate is nearly useless.

Image Fusion Method

The tomographic imaging of process parameters for oil-gas-water three-phase flow can be obtained through different sensing modalities, such as electrical resistance tomography (ERT) and electrical capacitance tomography (ECT), both of which are sensitive to specific properties of the objects to be imaged. However, it is hard to discriminate oil, gas and water phases merely from reconstructed images of ERT or ECT. In this paper, the feasibility of image fusion based on ERT and ECT reconstructed images was investigated for oil-gas-water three-phase flow. Two cases were discussed and pixel-based image fusion method was presented. Simulation results showed that the cross-sectional reconstruction images of oil-gas-water three-phase flow can be obtained using the presented methods.
