Introduction
Insertion type electromagnetic flow meter is a type of electromagnetic flow meter has been used throughout industries for more than 50years.  Insertion type electromagnetic flow meter comprise an electromagnetic sensing probe in  ABS or Polypropylene mounted on the end of a support rod. Q&T is a company that design and manufacture flowmeters with more than 15 years of experience. One piece Q&T insertion type electromagnetic flow meter can be used for pipe sizes between DN100mm and DN3000mm. It is an economic option for large pipeline applications. With hot-tap structure, it can achieve online installation easily. 
Advantages
Insertion Type Electromagnetic Flow Meter Advantages and Disadvantages
The main advantages of using electromagnetic flow meter is that it is with no moving parts, no pressure loss and require very less maintenance.
Insertion type electromagnetic flow meter provide more economical option for large pipelines flow measurement, while preserving the advantages of common type magnetic flow meter. Q&T insertion electromagnetic flow meter with simple structure and no moving parts. It is totally independent from the pressure, temperature and mechanical vibrations, density, viscosity etc. No scheduled maintenance required. It can achieve hot-tapping online installation.
Comparing with flange type electromagnetic flow meter, the limitations of insertion type electromagnetic flow meter is that it can only be used for larger sizes. It can only be used for size above DN100mm, for smaller sizes below DN100mm it is not available. The accuracy of insertion type electromagnetic flow meter is lower than flange type.

Insertion Electromagnetic Flow Meter Installation Requirement

  • In order to obtain a stable and accurate flow measurement, it is very important that the flow meter is installed correctly in the pipe system
  • Do not install the meter near equipment that produces electrical interference such as electric motors, transformers, variable frequency, power cables etc
  • Avoid locations with pipe vibrations for example pumps
  • Do not install the meter close to pipeline valves, fittings or impediments which can cause flow disturbances
  • Place the meter where there is enough access for installation and maintenance tasks
