Working Principle:
V-cone flow meter is a differential pressure type flow measurement device. So far it is more than 100 years since all kinds of flow measurement device that based on pressure differential theory been used. Pressure differential theory is based on energy conversion principle in sealed piping, means that to the steady liquid, flux and flow velocity's square root is direct ratio. We know that pressure will reduce when velocity increase, when medium approaches to cone the pressure is P1, but when medium is passing to cone's throttled area, because passing area reduced, speed increased, pressure reduced to P2, both P1 and P2 are connected to differential pressure transformer through pressure mouth. When flow rate is changed, the pressure differential value will increase or decrease accordingly.
