Water is an essential resource in the world and currently household drinking water is an important asset to save the life due to shortage of water in the earth. This paper describes the design and development process of an automatic control system for tap water using floatless water level sensor which can save wastage of water without the presence of any operator physically. This sensing system utilizes a combination of a solenoid valve, electromagnetic relay (a type of electrical switch), floatless level controller (61F) and electrodes (used to sense the watery level electrically). The developed system can automatically control the water tap accordingly when level sensor can sense the lower level of water tank. Also, the system has ability to activate the relay which starts solenoid valve. The entire process can continue until sense the upper level of water. After that the system deactivates the relay as well as the solenoid which can stop the water flow through tap, when the upper level is sensed. In summary, the developed system is able to control the water tap to protect the wastage of valuable water by this mechanism. This system is low-cost compare to other commercial systems, was tested to assess the success rate of the development . The result shows an autonomous plus robust monitoring system with satisfactory result which is relatively simple to install.

CHAPTER ONE
1.0 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 a certain 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.
1.1 OBJECTIVE OF THE PROJECT
The objective this work is constructing a device that will control the flow and pumping of water in the overhead tank or underground tank. This sensing system utilizes a combination of a solenoid valve, electromagnetic relay (a type of electrical switch), floatless level controller (61F) and electrodes (used to sense the watery level electrically).
1.2 ADVANTAGES OF WATER LEVEL CONTROLLER
Advantages of automatic intruder 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: these systems 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 control 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 APPLICATION OF THE PROJECT
It can be installed in
- hotels,
- hospitals,
- industries such as automobile,
- irrigation,
- and also at homes, or wherever water is pump either underground or overhead.
1.3 LIMITATION OF THE PROJECT
i. Automatic Water Level Controller (AWLC) will automatically START the pump set as soon as the water level falls below the predetermined level and shall SWITCH OFF the pump set as soon as tank is full or water level in the lower tank is at below minimum level. |

1.5 SCOPE OF THE PROJECT
This device saves wastage of water without the presence of any operator physically. This sensing system utilizes a combination of a solenoid valve, electromagnetic relay (a type of electrical switch), floatless level controller (61F) and electrodes (used to sense the watery level electrically). The developed system can automatically control the water tap accordingly when level sensor can sense the lower level of water tank. Also, the system has ability to activate the relay which starts solenoid valve
1.6 PROBLEMS OF THE PROJECT
Sensors used are built with conductive material, which means that they are subject to rusting or corrosion. When rusting occurs the sensors will stop conducting thereby causing this device will stop working.
1.7 PROJECT WORK ORGANISATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
Chapter one of this work is on the introduction to Water level controller. In this chapter, the background, significance, objective limitation and problem of Water level controller were discussed.

Chapter three is on design methodology. In this chapter all the method involved during the design and construction were discussed.
Chapter four is on testing analysis. All testing that result accurate functionality was analyzed.
Chapter five is on conclusion, recommendation and references.
CHAPTER FIVE
5.0 CONCLUSION
The course of undergoing this project has disclosed numerous important things about an automatic water level controller. Ranging from its economic importance and recommendation based on the use of this automatic water level controller. Hence with the successful design and construction of this project, a more efficient way of ensuring continuous flow and pumping of water is provided even in the absence of the operator. This provides the possibility that is can still put on his/her appliance (pump) in the absence of the user.
5.1 RECOMMENDATION
