Abstract

(Performance Test of Second Order Non Interacting Capacities Dynamic Process with Manipulated Variable –½, – ⅜, and – ¼) Dwidya Vania Putri* 21030114060020 Measurement of fluid flow rate is a very important variable in industrial process. This measurement is needed to determine the amount of fluid used in a process (flowing in and out of the process). One way of measuring fluid flow rate is by using Dynamics Process system or manual control system. The second order process contains two capacity elements, non-interacting capacities and interacting capacities configuration. In the second order process of non-interacting capacities, thelevelin both tanks clearly does not affect each other. The test was performed using a valve opening (interference) of –½ (-50%), – ⅜(-37,5%), and – ¼ (-25%). The change of the fluid flow rate from the steady state conditions is observed over a period of time and observation of the elevation level every 10 seconds. The resulting response is a kind of overdamped stable response (slow response). Keywords: level height, flow rate, dynamics process
