AVI-Mag™
Full Pipe Electromagnetic Flow Meter Technical Specifications
The AVI-Mag™ 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 pipe. The specific design of the multi-
electrode sensor compensates for variable flow profiles, including
swirl and turbulent condition.
The AVI-Mag™ 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-
Mag™ is the most economical flow metering solution for medium
and large pipe sensor sizes, reducing drastically installation costs.
The AVI-Mag™ 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-Mag™ comes in 2 different sizes in order to be used with
1 inch or 2 inch ball valves. The 1 inch AVI-Mag™ is available for
pipe sizes ranging from DN100 up to DN1500. The 2 inch AVI-
Mag™ is available for pipe sizes ranging from DN500 up to
DN2500. For larger pipe sizes, please contact FLOW-TRONIC.
