The V-cone flowmeter can improve the velocity distribution of the fluid. The flow of fluid in the pipeline is actually such a state that when the flow has reached a fully developed state, its velocity distribution is also uneven, that is, the flow velocity is faster near the center of the pipeline. The fastest in the center. The nearer the flow velocity is, the closer to the wall, the closer to zero at the tube wall.
Most flow meters involve the flow rate of the fluid when measuring the flow rate, assuming that the flow rate of the fluid in the pipeline is equal, without considering the difference between the speed of the actual flow, which is limited by the working principle of the instrument. To do so, the results can only be sacrificed at the expense of measurement accuracy (currently multi-channel ultrasound is developed to try to resolve the inhomogeneities in flow velocity).
This uneven flow rate has been well resolved in the V-cone flowmeter . Because the V-cone flowmeter throttle is installed in the center of the pipeline, it directly separates the fluid from the center of the high-speed flow, so that the fast-flowing fluids are brought close to the fluids with slower flow speeds and pull them together to flow together. As a result, the difference between the flow velocity and the flow velocity disappears, and the fluid becomes a true uniform flow.
