ABSTRACT:
A liquid metal level indicator is provided comprising a number of separate, substantially identical coils supported in a vertical array and adapted to be extended into a liquid metal bath. Means are provided for comparing the impedance of each coil to that of the next adjacent coil successively from one end of the array to the other to indicate the liquid level by the change in impedance of the coils due to the presence of liquid metal surrounding them.
