This is a PID regulator app which regulates the fluid level in a simulated tank with flow in and flow out. The regulator controls the flow out, and when turned on will adjust the flow out setting so that the tank fluid level matches the set value.
Controls for flow in and set value (point value) to emulate disturbance.
The user can control gain for Proportionate, integrative, and derivative to get increased understanding for how these parameters affect the regulator action
