Abstract:

The automatic DAM DOOR opening systems is a system where the DAM DOORS is controlled on the speed of the raising water. A situation araises where the raising water in the river may be very fast as the rainfall increases. If the river is blocked by a DAM then the speed of the raising water will obviously rise very soon. To prevent this raising and to prevent flooding of the river bank the DAM DOORS has to be opened but with a controlled speed because there is no point on opening the DOOR slowly if the water is raising at a quicker pace.

It is a circuit to measure the flow rate of water .Using this device one can determine the total volume of water raised in the river. The instrument is a microcontroller based system. It can have a optional of manual operation.

In manual method of measuring the flow rate of water, we need to observe the rise of water in river .As soon as water reaches a fixed point in the river , we press start button on the stopwatch .After the water reaches another fixed point, we need to press stop button on the stopwatch. The observed time and level are used to calculate the flow rate of the water.
Flow rate = volume/time

But in this procedure there are chances of errors . The device eliminates the errors and has the following features.

• Automatically senses the level and generates triggering pulses for counting of the elapsed time there by providing basis for calculation of the flow rate of waters.

• Includes the circuit for digital display of the elapsed time using MICROCONTROLLER as well as a 7-segment display.
