This project involves developing a PLC-based tank fill control system using a single feedback control loop with a strain gauge load cell. The system uses an Allen-Bradley SLC-500 PLC to control tank filling based on the load cell signal. The user sets the fill level setpoint from 5-100% via input. The tank fills and drains automatically based on the setpoint and feedback from the load cell signal conditioning circuit.
The slides in this presentation are used to review a solution to Lab 02 - Cascade System P&ID. The presentation provides a very basic overview of the cascade control system used to create the Lab 02 P&ID.

PLC based Multichannel Automatic Liquid Level ControllerVijay Badgujar
PLC based Multichannel Automatic Liquid Level Controller aims to control the level of liquid automatically so that water going waste due to overflow of tanks can be saved easily.
In this project , Two liquid level sensors are provided for overhead tanks and source tanks. Those liquid level sensors are low level sensors and high sensors. These sensors sense the level of liquid and operate relays and serves inputs to Programmable Logic Controller (PLC). Programmable Logic Controller (PLC) is programmed to control liquid level and maintain it at specific level in overhead tanks automatically.

User setpoint: 5 – 100% via input,
System activates via start PB #1,
Tank fill valve opens, pump starts
Tank fills to setpoint,
Pump stops, fill valve closes,
Tank drain valve opens after 10 seconds,
Tank drains to 5% level,
Tank drain valve closes, pump restarts, fill valve opens
Tank fills back to initial set point,
Process repeats; deactivates via stop PB #2
