Automatic Water Level Control System Using Programmable Logic Controller

Abstract

Automation is an essential component of industries as it enhances precision, productivity, safety, and mitigates potential risks arising from human errors. This paper addresses the use of MITSUBISHI’S FX1N32MR PLC (Programmable Logic Controllers) and Float switches to monitor and control the water level in a tank. The PLC receives water level information as signals from the Upper and lower limit float switches then in turn activates the appropriate Indicator LEDs and Pump as specified by the ladder logic program running on the PLC. The goal is to demonstrate a cost effective, affordable and efficient method of automating water level and consumption in a tank
