Designing and experimentally validating an autonomous liquid mixing and filling system based on a programmable logic controller (PLC) for small- and medium-sized industrial applications is the aim of this work. Within a single PLC framework, the suggested system combines automated filling, conveyor-based container handling, scheduled mixing, and liquid level management. Using ladder logic created in WPLSoft software, a Delta DVP-14SS2 PLC is used to coordinate sensors, solenoid valves, motors, and a pump. Stable operation, uniform mixing, and reproducible filling precision across several cycles are shown by experimental evaluation. The outcomes verify decreased human intervention and increased process efficiency. With potential for future growth through flow-based control, HMI/SCADA connectivity, and remote monitoring, the system provides a small and affordable automation solution.
