TRANSDUSERS: Which is used to convert Physical Changes into
Electrical Measures(Resistance, capacitance, inductance).

TRANSMITTERS: It converts Input signal(electrical measures)

or change in resistance to 0-10V)

Why is it necessary to use compensation leg to measure the liquid level in a closed or pressurized tank?
