A Mathematical Model of an Inductive Type Sodium Level Meter and Some Applications

A mathematical model of an inductive type liquid sodium level meter has been developed, which simulates behavior of the level meter in various environmental conditions. A test model was made to confirm experimentally the accuracy of the mathematical model. It was recognized that the mathematical model shows fairly well the behavior of an actual level meter. Error estimations were accomplished with this mathematical model. Errors are caused by the change of ambient temperature and by the surface tension of sodiumr.
