Method of detection of oscillation period for oscillatory densimeter |
摘要 |
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.
