A positive displacement (PD) flowmeters has been used for long years as it can measure volumetric flow directly. Since features of PD's are most exerted in oil related flow measurements, in present society which environmental issues are emphasized, they are required for high accuracy fuel consumption measurements in transport equipment industry such as automotive industry, as well as assuming an important role in cross-border transactions. Also, in recent years, development of secondary standards for JCSS registration is an urgent need; verification of our Screw PD Flowmeter is made, corresponding to such necessity.
