Pipeline vortex flowmeter for the reasons of low requirements for the site of the reserved piping

Project Overview

Compared with other types of flowmeters, pipeline vortex flowmeters have relatively lower requirements for on-site reserved pipelines. This is mainly due to the following reasons:

1. Short sensor length: the core component of the vortex flowmeter - the sensor part , designed to be relatively compact. Since its working principle is based on the Karman vortex phenomenon generated when the fluid passes through the cylinder, this mechanism does not rely on long-distance direct contact measurement, so the sensor body can be designed to be very short. The sensor makes its installation in existing pipeline systems more flexible, reducing the need for major changes to the pipeline layout.

   

2. The requirements for straight pipe sections are relatively loose: although the vortex street Flow meters still require a certain amount of straight pipe to ensure fluid stability and improve measurement accuracy, but the required upstream straight pipe length is generally shorter than some other types of flow meters (such as orifice flow meters). Generally recommended. The length of the upstream straight pipe section is 15 to 40 times the pipe diameter (DN), and the downstream straight pipe section is shorter, only 5 times DN. This means that the vortex flowmeter is a shorter length in situations where space is limited or modification costs are sensitive. Good choice.

3. Installation flexibility: The vortex flowmeter can be installed both horizontally and vertically, and when installed vertically, the medium flow direction is recommended from bottom to top, so that The installation flexibility further reduces the dependence on specific pipeline configurations and adapts to more on-site environments.

   

4. Anti-interference ability: Although the vortex flowmeter is resistant to flow velocity distribution distortion and rotation. Sensitive to flow and flow pulsations, modern designs optimize sensingThe sensor structure and signal processing algorithm improve its anti-interference ability and can adapt to less than ideal pipeline conditions to a certain extent.

To sum up, the vortex flowmeter due to its design features, such as short sensor length, relatively loose straight pipe section requirements, flexible installation method and enhanced resistance The interference performance makes it relatively low in requirements for on-site reserved pipelines, making it easy to install and maintain.
