In modern industry, the measurement of fluid flow is often required, which gives rise to flowmeters. Different directions of industrial development have led to various types of flow instruments, such as rotameters, electromagnetic flowmeters, vortex flowmeters, and so on. The connection methods for each type of flowmeter are not necessarily the same. According to customer requirements, even for the same type of flowmeter, the connection method may vary. The following briefly discusses several connection methods with pipelines.
1. Flange connection: This connection method is the most commonly used. Many glass rotor flowmeters, metal tube rotor flowmeters, electromagnetic flowmeters, and so on, all adopt this connection method. Simply fix the flanges at both ends to the flanges on the pipeline with bolts.
2. Threaded connection: Some flowmeters also adopt threaded connection, which is commonly used in the medical and food industries.
3. Clamp connection: This connection method is relatively advanced, and some flowmeters that do not have flanges themselves choose this connection. It can be clamped between the two sides of the pipeline base with bolts, and this connection method is relatively simple. Many vortex flowmeters adopt this connection method
4. Clean clamp connection: Nowadays, some pipelines with small diameters and low working pressures opt for this type of connection. With this connection, flowmeters can be quickly installed and removed, and daily cleaning and maintenance are also very convenient. It is uniformly rich in liquid-solid two-phase suspensions, such as mud, ore pulp, paper pulp, etc.
For flowmeter manufacturers, communicating with customers is crucial for the correct selection of flowmeters. During this process, it is inevitable to inquire about the required connection method. Besides clarifying the connection method, it is also necessary to specify the size, such as the size of the flange and the standard size of the flange; the type of thread, whether it is internal or external thread, and the size of the thread, etc. Choosing the correct connection method can ensure proper installation.
