Resumen
In this document it is shown the design and performance of laboratories equip with a system through which students can perform physical practices of industrial automation and control, such as measurement, control and monitoring of process variables. To meet the goal set, it was designed and built an automated prototype with the ability to control flow and level, the prototype has a system of pipes through which water flows driven by a pump. The pump speed is regulated by an inverter.
In both, flow control and level control, water flows from the reservoir into the test tank, and then into the reservoir again thus forming a closed water circuit.
For flow measurement it was used a KOBOLD turbine sensor with a measuring range from 2 to 40 [l / min], a measurement accuracy of 1.5%. The increase or decrease of the flow was made by varying the speed of the pump through the SINAMICS G110 drive speed.
