Answer / sandeep tripathi
c=s/d where s= surface area , d=distance between core &
magnetic field
when level is high then DP is low and when level is low
then DP is high

Answer / ramanathan
C=€A/D
Here € is relative permittivity of the material we going to measure
A- area of the probe
D- distance between the probe
here A and D are constant , so change in permittivity is directly proportional to level

Answer / nitin ku.sharma
since C=ka/d,here we can't change the area(a) so we are changing (d)the distance between them in order to change the capacitance of the capacitor,thus results in change in voltage and in case of transmitter we get change in currentdue to change in capacitance.
