Vijayalakshmi, C. Anuradha, R. C. Ilambirai, Viswanathan Ganesh Department of Electrical and Electronics Engineering, SRM Institute of Science and Technology, India Article Info ABSTRACT Article history: Received Nov 14, 2019 Revised Apr 26, 2020 Accepted Jun 26, 2020 In this paper, a Matlab based GUI and Propotinal Integral Dervative (PID) controller is designed to automatically regulate the flow-rate of the circulating fluid. When fluids are transported over long distances, the pressure and flow rate have to be monitored remotely in a control room. Using an HMI or Control Panels the flow rate can be increased or decreased to compensate for pressure drops or disturbances. This paper attempts to demonstrate such an Industrial Control Operation in a scaled-down environment. A Graphical User Interface or GUI is constructed which enables the Operator to monitor, as well as control an electronically actuated Control Valve which can efficiently regulate the flow-rate. Automatic operations have also been implemented using a PID controller algorithm, which tries to track the Set-point in Real-time.

INTRODUCTION Globally when transporting large volumes of fluids over long distances, pipeline provides the most commercially and economically sustainable solution for transportation. They find widespread adoption across all industries, from petroleum and fuels, to sewage and slurry, as well as clean water for irrigation or drinking purposes. Only requiring a pump for providing the pressure at one end, effortless transportation from remote locations become possible with very little additional manpower and monitoring. Thus, pipeline transportation beats traditional options such as trucks, or the railroad, with prices of the former being 2-3 times lesser. The only downside with pipelines is detecting the location of leaks, which are often very small and hard to track- down. But with the current generation of highly precise sensing equipment, and machine-learning aided tools, even that problem is being effectively tackled. An ultrasonic type flow meter is used along with linear array transducer for metal pipe sytem [1]. However, concentration of bubble has an effect due to ultrasonic. Proportional integral derivative (PID) is used to control flow of liquid and verified with lypanpuu stability analysis [2]. Comprehensive control for micro fluid is implemented using fabrication techniques [3]. An analytical numerical method is developed for finding error in flow of fluid when it crosses the bends for dufferent diameters of pipe [4]. Outlet pressure of pipe is controlled with PID controller using LabView software tool [5]. Time dependent method for different porous material for transportation of fluid is presented [6]. A reduction algorithm is introduced for ultrasound detection of flow rate [7].
