The AVI-MAG is an electromagnetic plug-in flowmeter. Multiple electrodes located in the same area over the entire sensor body measure and report the average flow rate over the entire diameter of the tube. The special design of the multi-electrode sensor compensates for variable flow profiles, including turbulence and turbulent conditions, and allows for installation without calibration.
The AVI-MAG can be installed without closing, draining or cutting the pipe (hot-tap installation). Welding flanges are not required and installation can take place in pressurized pipelines up to 16 bar.
The cost of installation is greatly reduced as it does not require heavy equipment (cranes, etc.) or extensive manpower. The AVI-MAG is the most economical flow measurement solution for medium and large pipe sensor sizes and reduces installation costs.
The AVI-MAG fits in tight spaces, can be submerged and offers complete accessibility. AVI MAG is available in two different sizes, 1.5 inches for pipe sizes from DN100 to DN1500 and 2 inches for pipe sizes from DN500 to DN2500. Larger pipe sizes on request.


  • Multi-electrode sensor that provides an accurate total flow profile that matches the performance of a full bore meter (0.5% accuracy)
  • Easy installation without interrupting operation
  • Cost-efficient solution for medium and large pipes
  • Removable in pipes under pressure for inspection, cleaning, calibration or verification
  • Sensor coated with food safe epoxy paint
