A Review on Liquid Level Detection using Programmable Logic Controller

Prof. Ravindra Lohar, Sanika Kumbhar, Ganesh Patil, Siddesh Patil, Gaurav Sawant

Abstract


In industries, effective liquid level control is essential. Sensors are used by PLC-based SISO and MIMO systems to provide precise automatic regulation, high dependability, and ease of use. [1] A PLC–VSD motor control system to lower energy and water loss in pumps is presented in the paper. VSDs improve efficiency and cost-effectiveness by adjusting motor speed based on demand, saving 15–20% energy and 10– 15% water. [2] A Mitsubishi PLC with pressure sensors and Omron SCADA over Ethernet is equipped with a swarm optimization- based PID controller. It guarantees quick reaction times and little variation in the water level.[3] ESP32 and ESP are used in a low-cost smart water pump system for water level display and real- time local control. Without relying on the internet, it guarantees reliable, low-latency functioning. [4]
