Full Profile Electromagnetic Averaging Insertion Flow Meter with Multiple Electrodes

The AVI-MAGTM (or MULTI-MAG for Russia & CIS-countries) is a hot tap full profile electromagnetic insertion flow meter. Multiple electrodes placed across the entire sensor body at equal area, measure and report the average flow rate over the full diameter of the pipe. The specific design of the multi-electrode sensor compensates for variable flow profiles, including swirl and turbulent conditions and allows installation without calibration on site.

The AVI-MAGTM 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.

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, calibrating or verification. It is particularly cost-effective for retrofit application.

The AVI-MAGTM comes in 2 different sizes in order to be used with 1,5 inch or 2 inch ball valves. The 1,5 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.
