Abstract: The information on how the superior performance of the V-cone flowmeter is realized is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. (1) The effect of uniform velocity on the fluid The fluid flow in the pipeline is actually such a state. When the fluid flow reaches the state of confiscated development without any obstruction and interference, its velocity distribution is: the closer to the center of the pipeline, the faster the flow velocity, Reach zu at the center. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the article details of how the superior performance of the V-cone flowmeter is achieved. (1) The effect of uniform velocity on the fluid The fluid flow in the pipeline is actually such a state. When the fluid flow reaches the state of confiscated development without any obstruction and interference, its velocity distribution is: the closer to the center of the pipeline, the faster the flow velocity, It reaches the fastest speed in the center, the flow velocity becomes slower near the wall, and it is close to zero at the wall. When most flow instruments measure the flow rate, they cannot change this uneven state, so they can only ignore the actual situation of the speed difference in the pipeline and assume that the flow rate is equal. The tower-type (shaped) flowmeter, because the cone is in the center of the pipeline, directly separates the fluid from the center of the high-speed flow, so that the fast-flowing fluids move toward the surrounding slow-flowing fluids and pull them to mix and flow together. The result of fast and slow mixing is that the difference in the original flow rate disappears, and the fluid becomes a truly uniform flow. The benefits brought about by the homogenization of the fluid flow rate are: the measurement signal truly reflects the actual value of the fluid being measured, and enables a sufficiently accurate differential pressure before and after the tower (shape) flowmeter at low flow rates. The reduction of , this effect is more significant, and this situation may have long been impossible to measure for traditional differential pressure instruments. (2) It has a strong anti-interference (vortex flow) ability. Everyone knows that when the fluid flow encounters obstacles Will produce“vortex flow”, which is the famous“Karman Vortex”Phenomenon, the vortex flowmeter works based on this principle. In the same way, throttling parts such as orifice plates and conical openings are also obstacles in the pipeline. In addition to the static pressure generated at the rear of the throttling part, a vortex flow must also be generated. However, this vortex flow is a useful signal for a vortex flowmeter, but it is a register interference for a differential pressure meter, see (Figure 4). This disturbance occurs downstream of the throttling (negative pressure side)“signal beating“phenomenon, it will seriously interfere with the measurement of normal signals. The tower-shaped structure is a side wall throttling, and the distribution of the disturbing flow at the rear of the throttling piece is equal and opposite (symmetrical distribution) and cancels each other, thus greatly reducing the degree of disturbance. Traditional throttling parts such as orifice plate are central throttling, and the direction of the generated interference flow directly points to the pressure taking port, which seriously interferes with the measurement signal, especially when the flow is small, the interference is even greater than the measurement signal and cannot work normally. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'How to achieve the superior performance of V-cone flow meter'
