ABSTRACT:
A densitometer (10) provides a chamber (24) within which a ferromagnetic bob (27) is shuttled back and forth by alternate driving of two coils (32 and 34). Measurement circuitry (FIG. 2) determines the density of the fluid inside the chamber (24) by comparing the stroke times in opposite directions.
