Working process of an enraf level gauge

Question

Write down the working process of an enraf level gauge?

Answer 1

Enraf level gaug e is depends on the ser powered null balance method. A displacer serves as continuous level sensing part. A two phase ser motor handled by capacitive balance system winds un-winds the evaluating wire till the tension in the weight springs is in balance with the weight of the displaced division immersed in the liquid. The sensing system in balance evaluates the two capacitance formed by the moving central sensing rod offered by the two the si plates and capacitor plates.
