Pipeline connection methods of electromagnetic flow meter

Electromagnetic flow meter is a high-precision, high reliability and long life flow meter, with flow sensor by direct contact with the pipe and the upper end of the signal converter. It is based on Faraday’s law of electromagnetic induction work and is used to measure the conductive liquid flows whose conductivity is more than 5μs/cm. In addition to the general conductive liquid flow, strong acids, alkalis and other corrosive liquids can also be measured. It’s also suitable to measure two-phase liquid-solid suspensions, such as mud and pulp.

Customers have to connect the necessary pipes after they receive the magnetic flowmeters. Usually the connection methods include the following:

  • Flange Connection.
    This connection method is more traditional. Both ends of the magnetic flowmeter can be connected to the pipe flanges with bolts fixed on them. This connection can be unidirectional installed. The sensor volume is relatively small which is only suitable for use in small pipes.


  • Clip Connection.
    This connection method is relatively advanced. Some electromagnetic flowmeter without flanges itself uses this connection and can be clipped in between two flanges of the pipeline with bolts in a relatively simple way. We need to know the the electromagnetic flowmeter installation method so there’ll be mistake during clip connection.


  • Thread Connection.
    There are also some small caliber electromagnetic flowmeters which use the thread connection. This connection is used generally in the medical and food industries. You can also find its application in the petroleum and exploration fields.


  • Sanitary Connection.
    Some small diameter piping uses this connection. Sanitary connection is often called clamp connection as they use clamps to fasten the magnetic flow meters. By using this connection, quick installation and removal, daily cleaning and maintenance are very convenient.
