Positive Displacement Flowmeters

Positive displacement flowmeter

In principle, positive displacement flowmeters requires no external energy such as electricity. The flowrate is calculated from the number of revolutions of a rotor(s) activated by the energy of the fluid. Generally, positive displacement flowmeters offer high accuracy measurement and are suitable for totaling the flowrate. Accordingly they are used in various kinds of applications including industrial instruments. Especially, since their use was approved for taxable transactions of petroleum products by the National Tax Agency in Japan, positive displacement flowmeters have been assuming a significant role in the field of certified custody transfer.
