Abstract
A vibration type liquid density meter comprising a base, a connector having a mass substantially smaller than said base, two hollow cylindrical elongated pipes each having two ends, one end of each pipe connected to the base, and the other end of each pipe connected to the connector with the pipes disposed substantially parallel to each other and a piezoelectric element attached to the connector for driving the pipes into self excited oscillation at their natural frequency. The liquid to be measured is supplied through the base, pipes and connector and the density of the liquid is measured by the frequency of oscillation with corrections for temperature.
