Liquid level sensing is based on the theory of a ratiometric measurement, using three sensors as shown in Figure 2: 1. LEVEL – The capacitance of the LEVEL electrode is proportional to the liquid height (hw). It has to be as high as the maximum (MAX) allowed liquid level. 2. REFERENCE LIQUID (RL) – The REFERENCE liquid electrode accounts ...

Learn an example PLC program to control a pump based on level sensors using ladder diagram logic with a video explanation.

Dec 3, 2017 · In industry, the water level control problem is a typical process control problem, and has been extensively studied in the literature. This report focuses on the design and implementation of a PLC-based water level control system. In this project, we have two primary objectives: the overall mechanical design of the system, and the

By using the sensory test and circuit of the tank, the water level regulator creates a difference in controlling the amount of water naturally. This system does not just simply monitor the water level in the tank; it also controls the motor when the space above the tank is empty.

Block diagram of liquid level control system. The aim of this paper is to use an economical technology to built the liquid tank level control the liquid level using arudino UNO...

In this laboratory exercise, the students model, calibrate, and control a two-tank level control system. In particular, this experiment exposes the students to the fundamental modeling principle of fluid mass balance, pressure sensor calibration, and a feedback control design methodology for a state-coupled, two-tank level control system. 2.

To developed this system, ATMEGA32 starter kit board is use to control pumping unit (motor), continuous fluid level sensor to measure the liquid level with LED display circuit, and temperature sensor is used to measure the current temperature of liquid inside tank.

The document provides block diagrams for several digital control systems, including: - A water level and temperature control system - DC motor position and velocity control systems - A missile angle of attack control system - A dual actuator hard disk drive position control system - A robot manipulator contour tracking control system - An ...

Fig 1 Block Diagram of water tank level monitoring and pump control system. The proposed system uses five sensors to sense various levels of the storage.

This also covers step-by-step procedures for designing a block diagram of this water level indicator in LabVIEW’s VI purpose. This helps us understand the principle of level detection for application.
