Flow meters and the connection method for MFCs
Common connection methods for flow meters
Flow meters are used to measure the flow rate of fluids—they can measure gases, liquids, and even steam. Depending on specific needs, various types of flow meters have been developed, including rotor flow meters, electromagnetic flow meters, vortex flow meters, orifice plate flow meters, and mass flow meters, among others. Each type of flow meter comes with its own set of usage requirements, and depending on the actual operating conditions, the installation methods may also differ. This article provides a brief overview of the different connection methods for flow meters.
1. Flange Connection
Flange connections are a relatively common type of joint. Most of our company's mass flow meters / Flow controllers can all be equipped with flange connections—simply secure the flanges at both ends to the pipe flanges using bolts. When placing an order, users can choose either a single-piece flange or a matched pair of flanges according to their specific needs.
II. Threaded Connections
Some flow meters also use threaded connections—glass rotor flow meters, gold rotor flow meters, and turbine flow meters all feature this type of connection. Additionally, certain mass flow meters / The flow controller may also opt for a threaded connection under certain operating conditions.
III. Clip-on Connection
Some flow meters that don’t have flanges themselves use this type of connection, which allows them to be clamped securely between the pipe’s base on both sides using bolts. This connection method is relatively simple. Many vortex shedding flow meters also rely on this kind of connection.
4. Clean-Type Clamp Connections
Today, some small-caliber pipelines operating at low working pressures use this type of connection. This connection method allows for quick installation and removal of flow meters, making daily cleaning and maintenance particularly convenient. It is ideal for handling liquids that are uniformly rich in solid-liquid two-phase suspensions, such as mud, mineral slurries, pulp, and other similar fluids.
V. Common Connections for Mass Flow Meters/Flow Controllers
Mass Flow Meter / The flow controller is directly radially connected to the pipeline; for applications involving relatively small pipe diameters, the most commonly used connections are: Ferrule connection, pagoda joint latex tube connection, quick-connect fitting, and quick-tightening mechanism. VCR Connections, etc. For pipes with relatively large diameters, the primary connection method is also flange coupling.
