Hi,
I am working on Level Indicator projects.I want circuit to match one requirement.
About the project.
We are measuring Level of liquid by the amount of output current.
The o/p current varies linearly with load resistance.The load resistance varies with level of liquid. Load resistance is inversely proportional to Level of liquid.
So in short-
Level increases->load resistance decreases->o/p current increases
So i want to design circuit to meet the above situation.

So specifications are as given below
Input voltage-any voltage between 5 to 20 volts DC (Constant)
Output current-varying linearly between 4 milliamps(DC) to 20 milliamps(DC) with load resistance.
Load resistance-varies between 1k to 2k linearly
