1.An Adaptive Calibration Circuit for Level Measurement Using Optimized ANN

2.Outline
Capacitance Level Sensor
  Present scenario of level measurement 
  Limitation on present techniques
  Objective of proposed work 
  A solution using Optimized ANN 
  Results & Conclusion 
  Further improvement 
  Any questions ???

3.Capacitance Level sensor
Liquid level in a storage vessel is one of the important variable to be measured.

Capacitance level sensor is the most commonly used level sensor.

Capacitance level sensor is nonlinear.

Capacitance level sensor output depends on permittivity of liquid under measure.

4.Expressions used

5.Present scenario of level measurement using CLS

6.Characteristic of the present technique

7.Limitation on range
Datasheet suggests that only 10% to 60% of the full scale of input range is considered for practical measurement.

8.Can level be measured with the same set-up if liquid is changed ???

9.System output i.e. level measurement with different liquid yields inaccurate results.

10.Can level be measured with the same set-up if the liquid temperature is varied???
