Monitor storage tanks that require flex probe solutions
Veeder-Root Mag-FLEX Tall Tank Probes are an ideal solution for fuel distribution depots, marine terminals, aviation fueling installations, and many other facilities where fluids are held in bulk. Compatible with both metal and non-metal tall tanks, the solution utilizes the proven Veeder-Root magnetostrictive probe technology installed in over 500,000 tanks worldwide. When paired with a Veeder-Root Automatic Tank Gauge (ATG), this creates a powerful inventory management system backed by the support network and reliability of Veeder-Root. It delivers accurate reconciliation of your most expensive on-site assets while eliminating the safety hazard of scaling formidable heights to determine inventory levels of aboveground storage tanks (ASTs).
Key Features & Benefits
- Probe Sizes: Provides monitoring capabilities from 5’ (1.5m) up to 72’ (22m) for tall tank applications in metal tanks; up to 41’ (12.5m) in non-metal tanks.
- Position Weight: A weight at the end of the probe cable ensures stable sensor positioning.
- Stainless Steel Probe Shaft: Protects the mag wire and improves probe durability.
- Single Point of Monitoring: Automate product level, water level, and temperature monitoring of storage tanks with a Veeder-Root fuel monitoring system.
- Water Detection: Identify possible water intrusion and ensure fuel quality with a water float system. The standard water float included detects water at the 5.5” (14cm) level. An optional low-level water float is also available for water detection at the 1.9” (4.8cm) level, which requires 4” (10.2cm) tank opening.
- Wireless & Wired Applications: For maximum flexibility, Mag-FLEX Tall Tank Probes are available for wired and wireless applications. When one is paired with a TLS-RF Wireless 2 system, it reduces installation time and cost by eliminating wiring between the probe and the ATG.
- Scalable Solution to Various Site Profiles: The Veeder-Root ATG portfolio offers a wide range of consoles to best suit various site configurations.
- Flexible Corrugated Probe Design: Enables easy transport and installation.

Flexible and Easy Installation
The flexible design of the Mag-FLEX Tall Tank Probes allows them to be coiled for compact, low-cost shipping and convenient transport to the tank top for easy installation.
After installation, these probes are held vertically in their operating position by an integral weight (for non-metal tanks) or magnet (for metal tanks). Their floats precisely track tank level changes and report the presence of water.
