A PXI based Operating-Strategy-Configurable ERT for Gas-Water Horizontal Flow Regime Identification
Electrical Resistance Tomography (ERT) technique has great prospective in industrial measurement and monitoring with merits of non-intrusive, non-radiant, visualization and etc. However, the application of this technique is restricted by its real-time performance. In this paper, the scheme of the Opetating-Strategy-Configurable ERT system based on PXI module instruments has been proposed. The Operating-Strategy-Configurable ERT System can work in different working Strategies including 16electrodes mode, 8-electrodes mode and 4-clectrodes for different flow regime, 16-electrodcs mode is used for imaging, 8-electrodes and 4-elcctrodes mode for regime identification and monitoring The result shows that, when the ERT system is working in dual-plane mode, the sampling speed of each plane is 625 frames/s at 16-electrodes mode, 1562frames/s at 8electrodes mode, and 3125 frames/s at 4-electrodes mode. It has improved the system real-time performance. The characteristic value which is extracted by the wavelet from the measured data of each cross section shows that the system has a good capacity of identification flow regimes.
