BACKGROUND

The significance of power factor (PF) correction is reflected in the large number of documents addressing this subject, in the engineering design effort, and in the numerous industrial plants that manufacture equipment for the control of reactive power and filtering of current harmonics . Some of the benefits derived from correct PF adjustment are:
1. reduced energy loss;
2. released generation, transmission, distribution, and substation cap ....etc

REMOTE BILLING OF ENERGY METER/WATER METER USING GSM MODEM
ABSTRACT:
Every month we can see a person standing in front of our house from Electricity board whose duty is to read the energy meter and handover the bills (electric or water) to the owner of that house . This is nothing but meter reading. According to that reading we have to pay the bills. The main drawback of this system is that person has to go area by area and he has to read the meter of every house and handover the bills. The Electricity board aut ....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
