Abstract
A liquid fluid level sensor responds to differential pressure forces exerted on a diaphragm as produced by exposure of liquid fluid to one side and of atmosphere to the other side. An arched resistance card is movable with the diaphragm to engage the mid-portion of a metal spring which progressively overlies greater portions of the card as the diaphragm moves thereby changing the resistance of a circuit including the card and the spring.
