Today all of us recognize the importance of sump tanks. In many places such as hostels, apartments, hospitals or even for household purposes, we use sump water. Hence, it is very necessary to control the sump tank. We bring forth an efficient Sump Tank Controller for our customers. Sump Tank Controller is a simple and inexpensive sump tank controller, which requires only one IC1, which consists of four NAND gates. The motor turns OFF when water level in the tank goes below low level and it becomes on when water level reaches to low level and it remains on until it goes high level. The motor turns OFF again as the water goes below low level.About the Circuit : As shown in the circuit diagram sensors HIGH and LOW are connected to the inputs of one of the NAND gate in IC1. Output of this NAND gate is given to the RS flop-flop build around two NAND gates in IC1. The output of RS flip-flop at pin4 is given to transistor T1, which drives the relay. The reference sensor denoted by ADJ is given positive potential through resistor R5/P3. When tank is full or at HIGH level, flip-flop gets set. Transistor T1 turns on which switches on the relay. Relay remains on as the water level goes below HIGH because of the flip-flop action. As the level goes below LOW, flip-flop gets reset and T1 turns off which makes relay off. Here LED D1 is used to give visual indication. When it glows indicates that the motor is on. When it turns off indicates that the motor is off.
