SCADA system in water storage tanks with NI vision LabVIEW

Advances in technology have driven the need for efficient water
management systems. This study presents a SCADA-based water
management system that integrates LabVIEW and Arduino to monitor and
regulate water levels and flow rates in a storage tank. The system uses an
HC-SRF04 ultrasonic sensor for water level measurement with 99.77%
accuracy and an HX710 pressure sensor, which achieves 98.54% accuracy.
The LabVIEW interface displays real-time data, giving users an intuitive
view of system performance. A proportional integral derivative (PID)
algorithm optimizes the water pump through pulse width modulation
(PWM), achieving water flow rate control. The Ziegler-Nichols method
tunes the PID parameters to Kp = 16.59, Ti = 1.102, and Td = 0.2755. This
tuning ensures the system maintains a consistent target flow rate of 4 liters
per minute (L/min) with minimal variation. Initial testing showed a 2.5%
overshoot but stabilized at the desired flow rate within 10 seconds,
indicating effective control. This SCADA system reduces water and energy
waste by enabling continuous real-time monitoring and control. The system
provides accurate data through a LabVIEW interface, ensuring effective and
informed operational decisions. This robust solution supports efficient water
management for industrial and environmental applications, contributing to
sustainability and resource optimization.
