AVI-MagTM FULL PIPE ELECTROMAGNETIC INSERTION FLOW METER

The AVI-MagTM is a hot tap full profile electromagnetic insertion flow meter. The measurement method is based on Faraday’s Law of Electromagnetic Induction: when a conductive liquid moves through a magnetic field, it produces a voltage. The voltage is directly proportional to the velocity of the conductive medium.

This sensor has multiple electrode pairs placed along the axis of the sensor at equal area. The velocity measurements are averaged together providing the average velocity across the pipe centerline. Flow is calculated by multiplying the average velocity by the cross-sectional area of the pipe.

The specific design of the multi-electrode sensor compensates for variable flow profiles, including swirl and turbulent conditions.

The AVI-MagTM is intended for the measurement of the water and conductive liquids which are not loaded with fibrous contamination such as: potable water, cooling or process water.

It can be installed without shutting down, emptying or cutting the pipe (hot tap installation). It does not require welding flanges and installation can be done in pressurized pipelines up to 16 bar.

Its cost of installation is largely reduced by eliminating the need for heavy equipment (cranes, etc.) or extensive manpower. The AVI-MagTM is the most economical flow metering solution for medium and large pipe sensor sizes, reducing drastically installation costs.

The AVI-MagTM fits in confined spaces, can be submerged and offers complete accessibility. It can be removed in pipes under pressure for easy inspection, cleaning, calibration or verification. It is particularly cost-effective for retrofit applications.

The AVI-MagTM comes in 2 different sizes in order to be used with 1 inch or 2 inch ball valves. The 1 inch AVI-MagTM is available for pipe sizes ranging from DN100 up to DN1500. The 2 inch AVI-MagTM is available for pipe sizes ranging from DN500 up to DN2500. For larger pipe sizes, please contact FLOW-TRONIC.

The maximum number of coils and electrodes will depend on the pipe inside diameter: the bigger the pipe diameter, the more electrodes will be placed along the sensor.
