1.0 Introduction
1.1 Background of the Project
There are two traditional methods for finding the level of water in a tank:
- Tapping down the side of the tank until the sound suddenly changes
- Removing the tank cover and dipping in a measuring stick.
The first method is unreliable, while the second method can be awkward and time-consuming. After all, who wants to climb to the top of a tank each time you want to find out how much water is inside it? For a long-life water level sensor, Bob Barnes of RCS Radio suggests that the probe be made out of 19mm plastic conduit fitted with stainless-steel radiator or fuel pump hose-clamps for the sensors
Suitably sleeved nichrome or stainless steel wire (“up the spout”) can then be used to make the connections between the clamps and the resistors. You will need to use Multicore Arax cored solder or Litton Arax cored solder (available from Mitre-10) when soldering nichrome or stainless steel wire (i.e. a corrosive flux is needed).
1.2 Objectives of the Project
The main objective of this project is to have a device which displays information based on the level of water in a tank or reservoir. It also ensure a stress free situation in the sense that the user can always be relaxed and just look at a display to know the level of water in the tank.
Other apparatus can be attached to the circuit so that it can turn ON a water pump when the tank is empty and turn it OFF when the tank is filled. With this apparatus on ground, one can be sure of regular water supply from the water tank.
1.3 Importance of the Project
The project, water level indicator is of vast importance with some of them listed below;
- It eliminates the stress of climbing a water tank just to determine its water level
- It ensures a constant water supply
- It can also be so constructed so that one don't have to always go and turn ON or OFF a water pump
- It also indicates the level of water in the tank at all time via the display device
1.4 Applications of the Project
The project can be used in homes, offices and industries. Wherever it is used, its primary aim is to check the level of water in a tank outside and display information on a digital read out. At homes, the project can be coupled to our water tanks. Here, three probes dipped inside the water determine the level of water and relay information to a microcontroller chip inside the project box.
With this information, output signal is sent via the output ports to a 7-segment display device. The information on this display tells the house owner the level of water in the tank.
The project can also be used in industries where it can be connected to a big reservoir tank from which water is supplied to areas where they are needed. Here, it can be further automated so that a water pump is turned ON whenever the water level is low. With this project, the industry can hardly go short of water as water is continually pumped whenever the level is low.
