Water-Level Controller
In most houses, water is first stored in an underground tank (UGT) and from there it is pumped up to the overhead tank (OHT) located on the roof. People generally switch on the pump when their taps go dry and switch off the pump when the overhead tank starts overflowing. This results in the unnecessary wastage and sometimes non-availability of water in the case of emergency. The simple circuit presented here makes this system automatic, i.e. it switches on the pump when the water level in the o..............etc

Simultaneous Noncontact Measurement of Water Level and Conductivity
water level and conductivity measurement is important in many applications. geophysics, ocean engineering, and the oil industry also rely on this. The gas/oil/water separation can be an example for this. for those application, the method of Noncontact measurement is suitable. For measuring the level, techniques such as Capacitance, radar, ultrasonic, and laser have been used. measurements of level and conductivity simultaneously has no tbeen possible. a novel inductive ..............etc

Components
The system comprises a Transmitter, converter module, float chamber, a feedline modulating control valve and an electronic microprocessor based PID/FUZZY controller.

Operation
A positive change of water level in the boiler alters the level transmitter inductance value of coil causing an imbalance in the system. This signal is transmitted through the electronic control box and connected to PID controller. Then the microprocessor-based PID level controller transmitted an electr..............etc

AUTOMATIC WATER LEVEL MONITORING SYSTEM


In most houses, water is pumped up to the overhead tank located on the roof from the ground. People generally switch on the pump when their taps go dry and switch off the pump when the overhead tank starts overflowing. This results in the unnecessary wastage and sometimes non-availability of water in the case of emergency.

Automatic Water Level Monitoring System presented here makes this system automatic, i.e. it switches on the pump when the water level in the overhead tank goes low and switches ..............etc

DIGITAL WATER-LEVEL METER
Digital Electronics Unit
In many applications a digital value is desired (for storage, analysis or accuracy). Although the above circuit can be used as an input to an analogue to digital unit, a more elegant and robust solution is to go directly to digital from the probe.

The capacitance probe is connected to an ICM7555 running in astable mode. The 7555 has an advantage as an oscillator for this application because the timing capacitor is grounded. The probe will be the timing capacitor.
The period of oscillation..............etc
