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.

Installation

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

Electromagnetic Flow Meter Maintenance
No routine maintenance is required
