This tool is made for controlling the water level to remain stable using NI-myRio 1950 with Proportional Integral Derivative (PID) control. This tool has an ultrasonic sensor input US-18 which produces a current output that is converted to voltage and water flow which is monitored with a flow sensor and programmed using LabVIEW software. Selection of the initial PID parameters using a combination of kp, ki, and kd which is set by the manual tunning method. The control results are focused on Proportional Integral Derivative (PID) based control with control performance criteria based on: overshoot and steady state error. The test results show that the PID control provides the best output response with a steady state error of close to 0.
