WATER LEVEL INDICATOR

Introduction

Water level indicator is used to measure the level of water in tank reservoir. Works on the basic principal of transistor. When the water level increases the no. of led’s on circuit glows. Water present in tank can easily be measure.

 

—COMPONENTS

—470 R*4, 1k*4 resistors

—A1015*4 transistors

—Buzzer (12v)

—LED*4

—12 volt battery source(DC)

 

—PROCEDURE

—In this circuit transistor switching is being processed. When any wire dipped in water N through water providing negative voltage on the BASE. Current begins to flow through collector  and LED’s starts glowing. When the water level reaches to maximum level buzzer will operate and starts giving alarm signal. This circuit has four levels(LOW, MID, NORMAL, HIGH).

 

—APPLICATIONS

—No need to go on the roof and check the water level.

—Same circuit can be used for under ground water storage.

—It is used to predict the arrivals of floods.

—It can be used to incoming and out going water in large water reservoirs.
