A Reliable and Economically Feasible Automatic Meter Reading System Using Power Line Distribution Network (TECHNICAL NOTE)
International Journal of Engineering, 2005Co-Authors: S K Wong, Mahmoud MoghavvemiAbstract:Automatic Meter Reading (AMR) is the remote collection of consumption data from customer’s Utility meters over telecommunications, radio, power line and other links. AMR provides water, electric and gas Utility−Service companies the opportunities to streamline metering, billing and collection activities, increase operational efficiency and improve customer Service. Utility company uses technologies that were developed several decades ago with the majority of the meters being read visually. With manual readings, considerable time is used to physically check out each unit. AMR becomes a viable option to overcome this problem of time wastage to obtain the meter readings. There are many different forms of communication links that can be utilized as the communication medium in an AMR system. One such link is the power line carrier or PLC. The advantages of using the PLC as the communication medium are readily apparent since the power line network is the property of the Utility company and its infrastructure is already there. However, power lines are never meant for communication and creates much noise and therefore, various modifications has to be made to make the PLC suitable to be the AMR communication channel. The AMR system consists of three major components: the meter interface module, communications system, and data concentrator. This paper details a feasibility study on the creation of a robust bi-directional/two-way communication system between an electricity meter and a distant control unit (data concentrator) over the low voltage (LV) distribution grid. Basic functions of the AMR system include the provision for remote connection and disconnection of meter and fraud detection features at both the meter interface and the data concentrator. As a support system to the entire AMR, batteries are utilized. They are especially important in the cases of power failures. Lithium-ion batteries are the type of batteries that are used as these batteries tend to last longer than most other batteries. The main advantage of this system is that it is a low cost system that produces very encouraging results and it can be implemented upon existing electro-mechanical meters without the need of purchasing new meters. With many existing meters being the electromechanical meters, the need for a high-cost, large-scale implementation of new electronic device meters to enable implementation of the AMR system is unnecessary. The cost of implementation is low and the benefits, especially economically, that it brings to the Utility company are immense.

A component based unified architecture for Utility Service in cloud
Future Generation Computer Systems, 2018Co-Authors: Mansura Habiba, Rafiqul Islam, A. B. M. Shawkat AliAbstract:Abstract The world is moving into a new era, Internet of Things (IoT) that means everything surrounding us will have their corresponding virtual image in the cloud and they will communicate with each other. In this research, a component based unified architecture for Utility Service in the cloud has been proposed for deploying Service and use of the application in an optimum way to make the maximum availability of Service within the limited duration of time and minimum configuration overhead. Our proposed architecture is divided into several layers and each layer is designed based on several components. Experimentally we observe through IBM Bluemix [ 28 ] proposed Utility Service system along with its working procedure and corresponding performance evaluation, which is promising. Therefore, we found proposed architecture is also capable to protect Utility Service and corresponding resources from external threats.

A unified architecture for Utility Service in cloud
Asia-Pacific World Congress on Computer Science and Engineering, 2014Co-Authors: Mansura Habiba, Rafiqul Islam, A. B. M. Shawkat AliAbstract:Today our world is ready to make the maximum use of cloud computing facility as like other daily most common utilities such as electricity, gas and water. However, currently the cloud is showing its limited effect in case of Utility Service system. The main lacking in cloud is the absence of unified architecture for deploying Service and use of application in an optimum way to make the maximum availability of Service within the limited time frame duration and minimum configuration overhead. In this research a cloud based unified architecture has been proposed for Utility Service system. In addition, the working procedure of proposed architecture with performance description is also added in this paper.

selecting a butterfly valve instead of a globe valve for fluid control in a Utility Service in the offshore industry based on an industrial experience
American journal of mechanical engineering, 2018Co-Authors: Karan SotoodehAbstract:Straight pattern globe valves are widely used in the oil and gas industry to regulate and control the flow of fluids. During operation, these valves are exposed to problems such as cavitation. Cavitation happens when the pressure in a liquid suddenly drops, leaving behind a bubble of gas. There are some strategies that can be used to mitigate the risk of cavitation, such as designing the valves as per API 623 standard, selecting a different valve type such as Y-Type or axial valves, or hard facing the valve internals. These solutions increase the cost of valve selection and are more suitable for the valves in process Services, such as valves containing hydrocarbon. The main question this research seeks to answer is whether a butterfly valve (e.g., wafer type) is a good replacement for a straight pattern globe valve in Utility Services such as water. It is noticeable that wafer type butterfly valves are much cheaper than globe valves, especially when it comes to exotic materials. 12 control valves in water Services in titanium and duplex in an offshore unit were selected for research. The manual valves on the bypass of the control valves were evaluated for globe or butterfly valve selection. The data analysis included two methods of cavitation analysis and pressure drop analysis. The risk of cavitation for both butterfly and globe valves is almost the same. The analysis shows that butterfly valves are slightly more prone to cavitation risk. When it comes to pressure drop calculation analysis, none of the globe valves were suitable. On the other hand, 6 butterfly valves were suitable for the fluid control after pressure drop and cavitation analysis. In conclusion, butterfly valves are recommended for fluid control in Utility Services such as water.
