V-cone flow meter principle and application

Differential flow meter is the traditional flow meter which has passed 100 years of history, in fact, of which there are many problems in the Venturi tube which could hardly be solved as the representative of the first generation flow meter. However, the experiment proved that the Venturi flow meter has lots of flaws, such as lack of precision measurement and over-pressure resistance. If we let V-Cone flow meter to the use of large industrial site, will greatly improve the accuracy of flow. The author also appeals to work out national standard of V-Cone flow meter in China as early as possible.
