这个小型企业创新研究(SBIR)第一阶段项目将评估开发具有电阻抗断层成像(EMFEIT)的电磁流量计的可行性，该流量计将满足多相流测量的需要。在理论分析的基础上，设计了基于电阻抗成像的电磁流量计的初步总成；(2)搭建了流量计硬件，并在PC机环境下开发了流量计的数据采集和处理算法；(3)在两相流回路中验证了新型流量计的性能。该研究的成功将为多相流研究提供有用的工具，为工业过程监测提供可靠的手段。如果成功，建议的流量计将用于石油、核、废水处理、化工、食品和生化加工行业。

This Small Business Innovation Research (SBIR) Phase I project will evaluate the feasibility of developing an electromagnetic flowmeter with electrical impedance tomography (EMFEIT), which will meet the need for multiphase flow measurements. Three major tasks are planned to demonstrate the feasibility of this development: (1) design a preliminary assembly of an electromagnetic flowmeter with an electrical impedance tomography based on theoretical analysis, (2) build the flowmeter hardware and develop its data acquisition and processing algorithm in a PC environment, (3) validate the performance of the novel flowmeter in a two-phase flow loop. The success of the proposed study will provide a useful tool for multiphase flow research and a reliable instrument for industrial process monitoring. If successful, the proposed flowmeter will be utilized in the petroleum, nuclear, wastewater treatment, chemical, food, and biochemical process industries.
