Mag-FLEX - Flexible Probe for Vertical Tanks


The flexible Probe Mag-FLEX is ideal for measuring liquid stocks in vertical tanks up to 15m length.

When connected to the Veeder-Root Systems, all the management and inventory control can be automatic, allowing an efficient remote and local stock control.

Once the Mag-FLEX Probe offers a high level of accuracy and reliability, it is designed for establishments that gather liquids in high volume tanks as basis for fuel distribution depots, marine terminals, aviation fueling installations, food, beverage and pharmaceutical industries.

It’s also recommended for high volume measurement of petroleum products, since it drives low electricity conductivity.

The Mag-FLEX Probe has a flexible corrugated design, which allows it to be wrapped up and packed in a compact way, guaranteeing low cost and easy transportation to the top of the tank where it will be installed.

Know the main benefits of the Flexible Mag-FLEX Probe.


  • After the Mag-FLEX Probe has been installed, the corrugated shaft is vertical oriented, maintaining its operational position to the determined weight installed in its lower end and to the magnet that holds itself into the tank basis.
  • The product measuring float registers precisely the changes in the tank level, and the water level measuring float, when installed, registers the volume of existing water. The Mag-FLEX probe operates with magnetostrictive measuring technology.


  • Veeder-Root proven quality and reliability, the market leader in fuel level measurements systems.
  • Low transportation cost. 
  • Simple installation, with no need of hiring lifting services.
  • Doesn’t require tank degassing for probe installation and maintenance.
  • Uses a single tank entry for level, temperature and water measurement.
  • A single measuring system can be used for subterraneous and aerial tanks.
  • Connects to other devices for a better stock management.
  • Reduces risk exposure by avoiding operator access in hazardous area and working at heights.
