Digital Sensors and Sensor Sysstems


Abstract: Various process tomography techniques have been developed to assist the multi-phase flow monitoring process. Generally, these systems are single-modality approach. Many times, single-modality is not able to provide sufficient information for multi-phase flow measurement. The spatial resolution and accuracy of methods like ECT and ERT is limited due to the inherently ill-posed inverse problems that have to be solved for image reconstruction. This limitation cannot be overcome by simply increasing the number of sensing elements. This paper presents a design and an overview study of a multi-modality system emergence of ultrasonic transceivers and electrical capacitance sensor. The composite dual-modality tomography system should provide complementary information to perform multiphase phase flow measurement.
