Abstract

PURPOSE: To offset errors owing to distribution capacities of coils and improve the safety of the apparatus by closely coupling a primary coil and a secondary coil and grounding these on the side opposite from the respecitve measuring faces of the levels of conductive liquid.
CONSTITUTION: The primary coil of a resistance 7 and the secondary coil of a resistance 7' are wound coaxially and are contained in a pipe form case, whcih is then dipped in liquid Na being conductive liquid and the liquid level thereof is thereby measured. Here, the resistance value of the resistance 7 on the primary coil side is let R, netural point A, distribution capacity 8, low level side B and high level side C and the resistance value of the resistance 7' of the secondary coil side is let R', neutral point A', distribution capacity 8', low level side B', high level side C'. Here, while the low level side B of the primary coil side is grounded, the high level C' side is conversely grounded on the secondary coil side. Thereby, the voltage being induced in the secondary coil may be linearly changed without being affected by the distribution capacities of the coils and the voltmeter 5 which is linearly graduated may be used for level indication
