Topic of project:
logic based automatic water level
Introduction
The water level alarm circuit is a simple mechanism to detect and indicate
the level of water in the overhead tank and also in the other containers.
Nowadays, all the householders/owners are storing the water in overhead
tanks by using the pumps. When the water is stored in the tank, no one can
identify the level of water and also, no one can know when the water tank
will fill. Hence there is an overflow of water in the tank, thus there is a
wastage of energy and water. To resolve this type of problems by using the
water level alarm circuit it helps and indicated the level of water in the
overhead tanks. The cost of the water level alarm circuit low and its use full
for the overhead water tanks, swimming pool boilers, etc.. The water level
alarm circuits are used in the factories, chemical plants, and electrical
substations and also in other liquid storage systems
Applications of Water Level Indicator
The water level indicator is used in Hotels, Home apartments,
commercial complex, and in factories.
The pumps used in the water level indicator are single phase motor,
submersible motor, and in three phase motor.
By using the two motors, two sumps, two overhead tanks we cannot
control by a single circuit.
Automatically the pump will switch ON/OFF when the water level in the
tank is empty and full.
We can also measure the fuel level in motor vehicles
The liquid level containers are huge in the companies
Advantages of Water Level Indicator
The water level indicators are low cost in the market
Any person can identify the water level easily by hearing the beep
sound
By using this we can control the water level safely and easily
Methodology:
The LOGIC GATE BASED AUTOMATIC WATER LEVEL INDICATOR as is
implemented on the proteas software to check what operations can be
performed and what kind of outputs are obtained. It can then be
implemented in the daily life applications.
The AUTOMATIC WATER LEVEL INDICATOR circuit which has been
implemented on the proteas software which helps to perform operations
with respect to daily life operations to some extent.
The circuit consists of:
A Water Tank device, called as Water Level Tank
4 inputs and 4 output pins attached to the water tank device
4 logic toggles for 4 different water level conditions at input
4 NOT GATES to limit the current flow
4 LEDS to indicate the water level
Grounds at the ends of LEDS
4 Buzzers with each led to indicate increased water level
Wires to join the components
Following is the working for LOGIC GATE BASED WATER LEVEL
INDICATOR CIRCUIT,
First of all, a tank of water will be placed either filled or unfilled depends
upon performer. Appropriate way is to start with an empty tank. After this in
the circuit, the 4 input pins are used which are attached with logic toggles.
At the output pin which is connected to the NOT gate and then with LED
will start glowing if the logic toggle for LOW WATER LEVEL is 1. If the logic
toggle state is 0 then the LED will simply not glow and no sound for low
water level will be listened.
Secondly, another logic toggle is attached with the input pin number 2. This
will show weather the water in tank is decreasing or going towards LOW
LEVEL. As soon as the water level reach this state the logic toggle state
will become 1 and the respective LED will start glowing. Also the buzzer
attached will sound for indication.
The third input pin is attached with logic toggle for REACHING HIGH
WATER LEVEL. If the toggle state becomes 1, it means that the water
level has start rising and is going towards the HIGH LEVEL. When the
water in tank reach this state, the respective LED will glow and it will be
observed that water level is rising. A buzzer will also ring for this state.
The forth and last input pin is used for indication of HIGH WATER LEVEL
in tank. The logic probe for this is if 1, it means water has high level in tank.
In order to stop the water to overflow after this level, an LED can be used
as is used in the circuit below. Led will immediately indicate for this level
and a buzzer will also tell that water has reached its high level in the tank.
Following is the circuit diagram for this whole process:
RESULTS:
Following are the results for WATER LEVEL INDICATOR CIRCUIT with
help of software implementation:
1) First, the water level in tank is LOW. So logic toggle at pin will be 1.
Other water levels are 0 at this time. So only led for low level will glow
and buzzer for this state will ring only.
Here is circuit
2) Now the water level will go up. This is an indication that water level is
now reaching at low level but hasn’t reached yet. The led and buzzer
will indicate only for this situation.
Here is the circuit
3) At this stage now water is going up and is indication for high level
reaching state. Led and buzzer will activate for this.
Here is the circuit
4) Now the water has reached its HIGH state in the tank. Respective led
and buzzer will activate for its indication.
CONCLUSION:
So it is concluded that DIFFERENT WATER LEVELS have been detected
with the help of this circuit. It will help in indication for water levels from
LOW to HIGH.
One can control the water level automatically so no need for manual
operation. It can also be used at large scale. in these circuits above only
one input state is in working for each level of water.
By the help of this useful results or beneficial results can be obtained.
