Will be provide - Essay Example red to the flow loop since the level loop is just pegged on the level valve just as where the flow loop also depends on both the flow and level valve. The level sensor’s gain was recorded at 121.28% m. Rationally an increase in the level percent led to an increase in the level as the tank increased. The effects of the derivative, integral and proportional actions on the system were observed with the turning of the flow level trainer. It was established through the turning that the system responded faster with a gain in the system. Involvement of the integral led to a decreased and went from slow reactions to unstable ones. Addition of the derivative caused the higher rate to do an overshoot. Tuning rules are critical part of learning how to manage a system. In this section of the experiment, familiarization with the operation of flow level trainer as well as data V system was acquired. The set point reactions and tuning parameters of the flow as well as level loop were observed. The first tuning parameters of the system are as indicated in table 2.3.1. The reaction to a set point alteration of the flow loop was examined by setting the rate of flow to 2.5 USGPM and level set point to 50 %.There was time allowed for the system to be able to settle so that its water level and flow rates were approximately at the allocated set points. Recording was done for the positions of the level and flow valves. Thus, changes were made for the flow set point from 2.5 USGPM to 3.0 USGPM. The system’s response was examined by recording the new level and flow valve positions in table 2.3.2. There was observation of the response to a set point change of the level loop by setting tank water level to 60% as well as the flow set point at 3.0 USGPM. Once again the system was given time to settle with the recording of valve and flow positions being done. Thus there was a reduction of the set point to 30% from 60% and the new flow ad valve positions were put down in table 2.3.3 The
