Desenvolvimento de um sistema de controle de vazão do canal hidráulico.

Abstract

This work describes the project and implementation of a flow control system for the hydraulic channel located in the engineering and environment laboratory at UFSM. Flow is among the most measured quantities in industrial processes, and within the laboratory, it is performed manually employing, among other methods, pourers. In the case of the environmental engineering laboratory, the options of studies for teaching, research and extension to the academic community are many, and the need for flow control for a better work efficiency becomes necessary. Therefore, case studies and equipment related to closed-loop control of the hydraulic channel appear as important mechanisms for future work in the laboratory. Finally, the flow control method employing ultrasonic sensors to measure the flow and its wireless communication with the frequency inverter responsible for driving the pump, proved to be a relatively effective and met the proposed requirements with an acceptable margin of error between the traditional method and the flow measurement method proposed in this work allowing flow control in the channel.
