Design And Construction Of An Intelligent Overhead Tank Water Level Indicator With Display And Alarm

ABSTRACT

This project is on intelligent overhead tank water level indicator with display and alarm.

This circuit detects and controls the water level in an overhead tank or any other container. This system monitors the water level of the tank and automatically switches ON the motor when ever tank is empty. The motor is switched OFF when the overhead tank or container is FULL. Here the water level of the tank is indicated on LCD (Liquid crystal Display) and alarm (buzer). Using this system, we can avoid the overflow of the water. But, here we are designing the circuit which is used to detect and control the water level automatically in overhead tank using 8051 microcontroller

An intelligent overhead tank water level indicator with display and alarm is an Electronic Equipment which when electrically connected to the starter of any given pump -set motor will control the operation of the pump- set depending upon the water level in the Source and Destination Storage Tanks. It Switches ON the Pump-set when Water level drops below pre-set level in Overhead Tank, Switches OFF the Pump-set when Water level in Overhead Tank becomes full thereby giving an indication through an LCD and alarm.

CHAPTER ONE

• INTRODUCTION

The Water Level Controller System is an Electronic Equipment which when electrically connected to the starter of any given pump -set motor will control the operation of the pump- set depending upon the water level in the Source and Destination Storage Tanks. It Switches ON the Pump-set when Water level drops below pre-set level in Overhead Tank, Switches OFF the Pump-set when Water level in Overhead Tank becomes full ,Switches OFF the Pump-set when Water level is low in tank , and Switches ON the Pump-set when there is sufficient water in the tank.

Automatic water level controller circuit is a engineering project. It can automatically switch ON and OFF the domestic water pump set depending on the tank water level. You can implement this motor driver circuit at your home or college using less costly components. The main advantage of this water level controller circuit is that it automatically controls the water pump without any user interaction.

The automatic pump controller eliminates the need for any manual switching of pumps installed for the purpose of pumping water from a reservoir to an overhead tank. It automatically switches on the pump when the water level in the tank falls below a certain low level, provided the water level in the reservoir is above an overhead level . Subsequently, as the water level in the tank rises to an upper level (M), the pump switched off automatically. The pump is turned on again only when the water level again falls below level in the tank, provided the level in the reservoir is above R. This automated action continues.

There are Four parts in this project:-

(i) The Sensor Part

It is generally a fixed support inside the tank having some nuts and bolt with wires coming out.

(ii) The Circuit Part

It comprises the brain of the module, where in all the various inputs from the sensors are fed. It is the unit from where you will get all the information of how much of water is in the tank.

(iii) The Power Supply 

It is the part where in you will be converting the A/C voltage to a regulated voltage of 12V to the Circuit.

(IV) The Buzzer Part

It is responsible for bringing up the sound when the water level fills up in the tank. It will also be having a speaker or a buzzer to alert.

1.2                         OBJECTIVE OF THE STUDY

• To institutionalize social regulations level that govern the allocation, use and management of water for the different purposes.
• To achieve equitable and sustainable access to groundwater to all farmers through sharing of resources and socially regulated demand management of the resource.
• To achieve equitable and secure access to water for drinking, sanitation and domestic needs at affordable costs for all households or company within the project area and project period

1.3      SIGNIFICANCE OF THE STUDY

This device produces a beep sound when the water tank is completely filled by water. The advantage of this project circuit is that it saves water from accidental over flow .Other advantages are as follows:

• Suitability: These water level controllers are ideally suited for normal water as well as for ultra low conductivity water with less than 1 micro/moh.
• Easy to Operate: this system come fitted with sensitivity setting which can be provided externally on a dial or with internal settings.
• Settings : It is equipped with technology which works on low or high sensitivity settings on the same machine and thereby saves costs of buying and using two different machines.
• Materials of Construction : this water indicator system is  protected the against corrosion.
• Safety : This system is highly insulated, leakage proof and works without creating any noise.

• Save roofs
• Save water
• Save electricity

1.4           FEACTURES OF WATER LEVEL INDICATOR

1.5      APPLICATIONS OF WATER LEVEL CONTROLLER CIRCUIT USING 8051

• Used in big buildings where the manual monitoring is difficult.
• Used in industries to control the liquid level automatically.
