ABSTRACT:
An oscillation period of an oscillating tube of an oscillatory densimeter is detected while liquids of which densities are to be measured are introduced into the oscillating tube. When the oscillation period exceeds a predetermined threshold, a time for which the introduction of liquids should be further continued is determined by multiplying the time from the start of the introduction to occurrence of the exceeding by a predetermined ratio.
