What connections are available for pipeline vortex flowmeters?

Project Overview

Pipeline vortex flowmeter, as an instrument widely used in fluid flow measurement, the choice of its connection method is directly related to the accuracy of measurement and the stability of the system. This article will introduce in detail several common connection methods of pipeline vortex flowmeters and discuss their applicability in different application scenarios.

1. Flange connection Flange connection is one of the most common connection methods for pipeline vortex flowmeters. It installs flanges on both ends of the flow meter and uses bolts to tightly connect the flow meter and the pipeline. This connection method has the advantages of simple structure, convenient installation, and good sealing performance, and is suitable for pipes of various diameters. In flange connections, flanges of different materials and specifications need to be selected according to different pipeline pressures and temperatures to ensure the reliability and safety of the connection.

2. Snap-on connection Snap-on connection is a fast and convenient connection method, suitable for small and medium diameter pipes. It uses chucks, seals and fasteners to work together to achieve a stable, sealed installation. The chuck is placed on the pipe, and the sealing ring ensures no leakage. After tightening, it facilitates the rapid installation, disassembly and maintenance of the flow meter. It is suitable for multi-scenario applications and ensures measurement accuracy and system safety.

3. Welding connection

Welding connection is a connection method that directly welds the flow meter and the pipeline together. It has the advantages of firm connection, good sealing, and strong corrosion resistance, and is suitable for application scenarios with high pressure, high temperature, or corrosive media. However, welding connections have high requirements on welding process and welding quality and need to be performed by professionals. At the same time, since the welded connection is irreversible, it cannot be easily disassembled and repaired once the installation is completed.

4. Threaded connection

Threaded connection is a connection method suitable for small diameter pipes. It processes threads on the pipe and flow meter, and uses the engagement of the threads to connect the two together. Threaded connections have the advantages of easy installation and easy disassembly. However, in applications with high pressure, high temperature or corrosive media, special thread materials and seals are required to ensure the sealing and safety of the connection. In addition, due to the relatively poor sealing of threaded connections, measurement accuracy and system stability are easily affected by media leakage. When selecting the connection method of the pipeline vortex flowmeter, factors such as the measurement medium, pipeline pressure, temperature, and caliber need to be comprehensively considered. For application scenarios with high pressure, high temperature or corrosive media, you need to choose a connection method with excellent sealing and corrosion resistance; for small and medium diameter pipes, you can choose a connection method that is easy to install and disassemble; for large diameter pipes, you need to choose a connection method Strong connection and good sealing.
