How do you describe water level indicator project?
When water level increases and touches the sensor, the Red LED will glow indicating that there is water within the tank. As the water level continues to rise and reaches half the tank, Yellow LED will glow. When the water in the tank rises to full an alarm is made by the buzzer as an indication that the tank is full.
What are the applications of water level indicator?
The uses of a water level indicator include the following applications:
- Can be used in water tanks to control water levels.
- Automatically turn ON/OFF pumps.
- Can be used in factories, commercial complexes, apartments, home,
- Fuel tank level gauging.
- Oil tank level control.
- High & low-level alarms.
- Pool water level control.
What is simple water level indicator?
Simple Water Level Indicator. When water is rising the base of each transistor gets electrical connection to 6V AC through water and the corresponding probe. This, in turn, makes the transistors conduct to glow LED and indicate the level of water.
Which sensor is used in water level indicator?
A magnetic float sensor is a device used to detect the level of liquid within a tank. The switch may be used in a pump, an indicator, an alarm, or other devices. Magnetic float sensor is an electromagnetic ON/OFF switch. It helps to sense the level of water present in the overhead tank or sump.
Why bc547 transistor is used in water level indicator?
Water tank overflow is a common problem which leads to the wastage of water. In this project I am using the transistor based water level indicator circuit is very useful to indicate the water levels in a tank. If the water level is full, then the circuits beeps through the buzzer notifying that the water level is full.
How do water alarms work?
A common design is a small cable or device that lies flat on a floor and relies on the electrical conductivity of water to decrease the resistance across two contacts. The device then sounds an audible alarm together with providing onward signalling in the presence of enough water to bridge the contacts.
Why are resistors used in water level indicators?
When the water level reaches to Point A in the tank, the positive side of the battery gets connected to the base of the Transistor Q1 through the water. You can see resistors (R1, R2, R3) at the base of each transistor, which is used to limit the maximum Base current.
What is water level tool?
Water levels are a simple tool that have been used for a long, long time. Though their low-tech compared to fancy laser levels, they can actually be more accurate over long distances. They work because the water in the tubing will try to find an equilibrium, which you can use to find a level measurement.
How do water levels work?
A water level works on the principle that a liquid always seeks its own level, it doesn’t matter if the body of water is a bathtub or a lake. As long as there are no outside influences at work (such as the wind or tides), the water at one end of the body of water is the same height as the water at the other end.
How does water level indicator work?
Water level indicators let people know how much coolant or water their radiator can access. They are useful when fixing cooling system hose leaks. Water level indicators can also indicate if there is a slow leak.
What is a water level indicator?
The water level indicator is defined as a system which gets the information about the water level in reservoirs or in tanks which is used in homes. By using the water level indicator we can overcome the overflow of water from the tankers.
What is a water level sensor?
A water level sensor is a system designed to detect the flow of water in a container. The latest water level systems use digital sensor for determining the volume of water in a tank.
What is a water flow indicator?
Water meters also have a low flow indicator. This is usually a small, triangle or wheel that spins when water is flowing through the meter. Look for movement on the low flow indicator while all water used has been stopped. If there is movement, water is still flowing through indicating a leak.
