Diseño y construcción de un equipo para control de caudal de líquidos

Abstract

An equipment to measure and control the amount of liquids for tha processes control laboratory of Science Faculty at Escuela Superior Politecnica de Chimborazo has been designed and constructed, so that students can use it as a didactic and research material since there wasn’t any one equipement which controls a process variable.

Theoretical aspects were studied to understand the equipment working; to identify the unit, a experimental study was designed to definy the variable to be measured and the signal stimulus to be applied the system.

The main components of the process control were identified: sensor - transmitter will be in charged of the measurement in the control system and transmit the corresponding transmission value, the controller will be the brain of this system and the bump will show the different speeds of fluid applied to the system.

Sampling was at random simple in periods of time without changing the time of it because with this equipment tha variables could be taken directly. As a result from the research, an automatic equipment to control the sensor of flow was gotten.

From the selection process and gauge operation, it is concluded that the equipment got efficient results up as 90% of its total capacity. They materials which were used will be useful to expetience at the Faculty. It is recommended to implement equipment like this one which can serve as a didactic material for the students. In addition, the it will be able be used in different faculties because it thas laboratory practice programming. It is also recommeded to take several steps to carry out a better calculus in the laboratory practices.
