PROJECT CERTIFICATION

It is certified that batch (2013-2014) of B-Tech (pass) comprising the following members:

1. MUHAMMAD ALAMGIRMP-130132. AZMAT-UL-ALLAHMP-130053. BASIT NISARMP-130064. AHMED ALIMP-130045. MUHAMMAD HASSANMP-130156. MUHAMMAD MANNAN RAFIQMP-13017

Has successfully completed the assigned task of fabrication of Level/Temperature/Flow Control Trainer under the supervision of Mr. Babar Sayeed.

Mr. Babar Sayeed(Project Advisor)

Engr. Ejaz Hussain Khan (Director of PSTC, Karachi)

PREFACE This project is prepared to provide knowledge about control of flow, level and temperature of liquid stored in tank. After completely studying the report and working on training module. He/she can easily understand about controlling the rate of flow, level and temperature of water under prescribed conditions. The process unit and the control loops used in measuring experiments for level, flow and temperature are described in detail.The monitoring and control of level, temperature and flow of liquid are an integral part of most of the processes in industry. The project Level/Temperature/Flow control Trainer is an effort to introduce the measurement, monitoring and control of level, Temperature and flow by means of a simple trainer utilizing water as a medium.The characteristics and term have been described from basic, making it easy for reader to understand the technology and the components used in the project.The project report is well illustrated by drawing and images to make it easier for the reader to understand.We hope that the short comings may be waived helping in view that project and report was completed in a short period of time. ACKNOWLEDGMENT

All praises and thanks to Almighty ALLAH. The lord and creator of this universe whose power and glory all things are accomplished. He is the merciful, who bestowed on us the potential, ability and an opportunity to work on this project.Our first experience of project has been successfully, thanks to the support staff of many friends & colleagues with gratitude. We wish to acknowledge all of them. However, we wish to make special mention of the following.First of all we are thankful of our project advisor Mr. Babar Sayeed under whose guideline we were able to complete ourproject. We are whole heartedly thankful to him for giving us hisvalue able time, attention and for providing us a systematic way for completing our project in time.We express our special thanks to honorable Engr. EjazHussainKhan (Director of Pak Swiss Training Centre Karachi) for extending his good support. We are thankful to our institute and all our faculty members without whom this project would have been a distant reality. We are also appreciate and thankful to our family for their moral and monetary support.
