Why do you need a long enough straight pipe section to install a flow meter?

Abstract: The information on why a long enough straight pipe section is needed to install a flow meter is provided by the excellent flow meter and flow meter manufacturer and quotation manufacturer. Although there are many types of flowmeters, their measurement principles are the same. The accuracy of the measured flow rate is not only related to the accuracy of the flowmeter itself, but also to its installation position. The ideal installation position of the flowmeter is that the flow state of the upstream and downstream fluids is single-phase stable. flow, this. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details of why a long enough straight pipe section is required to install a flowmeter. Although there are many types of flowmeters, their measurement principles are the same. The accuracy of the measured flow rate is not only related to the accuracy of the flowmeter itself, but also to its installation position. The ideal installation position of the flowmeter is that the flow state of the upstream and downstream fluids is single-phase stable. Therefore, the influence of the upstream and downstream local resistance pipes of the flowmeter on the fluid flow state does not directly affect the measurement accuracy of the flowmeter. In short, the fluid must form a typical flow velocity distribution (laminar flow velocity distribution and turbulent flow velocity distribution) in a circular pipe before it can be calculated and measured accurately using a mature mathematical model. However, this typical flow velocity distribution must be formed only when the flow in the pipe is fully developed, that is, there is a long enough straight pipe section to form. However, if the fluid flows through the blocking parts (elbow, tee, valve, etc.), the flow velocity distribution will be distorted and vortex will be generated. In this case, the fluid will become an insufficiently developed pipe flow. A section is all different and changing over time. Only at the end of a very long straight pipe section or after adding a rectifier can the velocity distribution return to a fully developed pipe flow, which is the fundamental reason why many flow meters require a long enough straight pipe section. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
