Abstract
An oscillation period of an oscillating tube of an oscillatory densimeter is detected while the oscillation of the oscillating tube is maintained by applying an external force in the form of a pulse signal to the oscillating tube in one direction each time the tube passes the original place in that direction so that a stable oscillation free from any influential distortion can be obtained.
