The successful point development and design is a qualitative leap in the principle of differential pressure flowmeter. It uses the throttling effect caused by V cone in potential flow to measure the total flow according to the pressure difference between upstream and downstream. Compared with general throttling parts, it changes the reasonable layout of throttling, from the orifice throttling of management center to the annular throttling.

Practical application proves that compared with other instruments, V-cone Flowmeter has the advantages of long-term high accuracy, good reliability, small limitation of installation standard, wear resistance, wide detection range of bar flowmeter principle, small pressure loss and suitable dirty medium. And the accuracy of the bar flowmeter itself as a potential flow ballast has become an outstanding new flowmeter with unique characteristics. The V-cone Flowmeter, composed of V-cone controller and differential pressure transmitter, can accurately measure the total flow of various media in the wide range of Reynolds number (8 × 103 ≤ re ≤ 5 × 107).
