| Abstract | The paper presented a method to optimize the excitation coils in the electromagnetic flowmeters (EMFs). The optimized coil size was obtained by minimizing the standard deviation of the induced voltage for different asymmetrical flow profiles. The voltage detected between the two electrodes was calculated based on the weight function. A pair of parameters, i.e. circular span angle and axial length, was selected as the optimized parameters of the excitation coils. The optimization was then implemented with different values of the parameter pairs. As a result, the parameter pair that leads to the minimum deviation of the induced voltage for different asymmetrical flow profiles was selected for the optimized coil. The model of EMF with diameter of 150mm was established. The results showed that the EMF composed of the optimized coils was less sensitive to the flow profiles than the EMF composed of the un-optimized ones. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
