Working process of an electronic level troll

Question

Write down the working process of an electronic level troll?

Answer 1

The differences in level of buoyancy resulting from alter in liquid level differ the net weight of the displacer rising or declining the load on the torque arm. This amend is directly proportional to amend in level and particular gravity of the liquid. The resultant torque tube movement varies the angular motion of the rotor in RVDT give a rotor changes proportional to the rotor displacement that is amplified and switched to a D.C. current.
