FLOW CONTROLE DEVICE
[attachment=32738]
SPECIALITIES:-
This project display the level of water or fuel tank in a tank. By using this project we can put on/put off the motor as per lavel of water in the tank. Thus the water and electric consumsion is saved.
DESCRIPTION
The circuit mainly depends on the IC CD4049. This is a IC with 6 inverter. The pin no.1 of IC is positive supply pin and pin no.8 is negative supply pin. The cathode of LED are connected at pin no.2,4,6,10 and 12. The anode of the LED is connected to the ground through the resistance 100E. Generally the output of the inverter gates are kept high through all these pins. The input pins of the inverter are connected to the sensor connect wire through the pins 3,5,7 and 11. All these wires are touching at different lavel of water in the tank. This is shown in the diagram. Beside this a conector wire from positive supply goes to the deepest level of water in tank. The LED a starts glowing when output at pin no.2 is low due to high lave at the pin no.3. This happens when water level in tank is at a and sensor connector wire works. In the same way LED B, LEDC, LED D and LED E gets on reaching the water level at B, C, D and E.
The sensor connector wires from A to E and Q should be thin matelic rod and this should be on a non conductin frame tied closly with a clamp.
Working
A flow control structure is a device that alters the flow of water in a stream, drainage channel or pipe. As a group these are passive structures since they operate without intervention under different amounts of water flow and their impact changes based on the quantity of water available. This includes weirs, flow splitters and proprietary-design devices that are used for stormwater management and in combined sewers.[1]
Flow-control structures are known to have existed for thousands of years. Some built by the Chinese have been in continuous use for over 2,000 years. The Chinese used these structures to divert water to irrigate fields and to actually deposit silt in specific areas so that the channels were not blocked by silt build-up. Structures like this required yearly maintenance to remove the accumulated silt.
More modern structures add to these basic principles. In Hawaii, there are numerous flow-control structures that have been built to irrigate thepineapple and sugar cane fields. The purpose of these structures is to divert water into the various canals and to keep them full. When over full, they dump excess water back into either streams or other canals. Among the simplest is a low dam across a shallow stream, forcing all of the water to one side to allow it to be easily collected in a canal. This can keep a canal full even with very low flows in a stream.
