Veeder-Root tank gauges and probes

Technical selection of Veeder-Root equipment: TLS-450PLUS, TLS4 and TLS4B consoles, USM and UIOM modules, MAG Plus probes, MAG-D density probes, Mag-FLEX probes and leak sensors.

TLS-450PLUS automatic tank gauge consoles

The TLS-450PLUS console handles fuel inventory and leak detection at fuel stations and depots. The standard configuration accepts up to 64 inputs, expandable to 256, and BIR reconciliation covers 32 tanks. It has a color touch screen, line leak testing on 16 lines and runs at 0 to +40 °C.

USM, UIOM and interface modules for TLS-450PLUS

The USM 0332812-001 module takes signals from probes and leak sensors, while the UIOM 0332813-001 handles discrete inputs and outputs. The 0333564-001 relay module is rated at 10 A. External systems connect over serial ports through RS-232/RS-485 modules such as 0332870-001.

TLS4 and TLS4B consoles for industrial tanks

TLS4 and TLS4B are compact consoles for commercial and industrial tank monitoring. TLS4 software supports 12 universal inputs and TLS4B supports 6. The multipoint tank chart holds up to 5,000 points, data is stored for at least 3 years, and TLS4 accepts one TLS-XB expansion box.

MAG Plus probes for fuel storage tanks

The MAG Plus probe, built from stainless steel tubing with a polymer canister, measures product level, water and temperature in underground and aboveground tanks. Versions cover inventory only or 0.1 or 0.2 GPH leak detection with 2 and 4-inch float kits. ATEX series 846367, UL series 846397.

MAG-D density probes 846367-9XX

The MAG-D probe measures fuel density during a delivery using a temperature-compensated density factor. The range is 690–800 kg/m³ for gasoline and 800–900 kg/m³ for diesel, accuracy ±2.0 kg/m³, minimum fuel height 200 mm. Code 846367-9XX is the ATEX inventory-only version.

Gasoline: 690–800 kg/m³
Diesel: 800–900 kg/m³
Accuracy ±2.0 kg/m³
Minimum fuel height 200 mm

Installation kits and floats 846400, 886001

MAG Plus kits include a product float, a water float, a probe insulation boot and cable. Gasoline and diesel kits include 846400-100 and 846400-001. Kits 886001-100 for gasoline and 886001-101 for diesel serve MAG-D probes only, as MAG-D floats do not fit MAG Plus probes.

Mag-FLEX probes for tall aboveground tanks

The corrugated Mag-FLEX probe serves aboveground tanks at fuel distribution depots, marine terminals and aviation fueling installations. It covers 1.5 to 22 m in metal tanks and up to 12.5 m in non-metal tanks. The standard water float detects water at the 14 cm level.

Leak sensors for sumps and interstitial spaces

Veeder-Root sensors monitor dispenser pans, containment sumps and the interstitial space of double-wall tanks. The Mag Sump Sensor detects hydrocarbons or water, while the dual-point hydrostatic reservoir sensor separates high and low level alarms in brine-filled tank walls.

Choosing a Veeder-Root console for the site

Veeder-Root builds automatic tank gauge consoles for fuel inventory and tank leak detection. TLS-450PLUS accepts up to 64 inputs, expandable to 256, and runs BIR reconciliation for 32 tanks; it fits large fuel stations and depots.

Commercial and industrial sites use the compact TLS4 with 12 universal inputs or TLS4B with 6 inputs. TLS4 accepts one TLS-XB expansion box.

Probes for underground and tall aboveground tanks

The MAG Plus probe serves underground and aboveground tanks, measuring product level, water and temperature, and leak detection versions also test tank tightness. The MAG-D probe adds fuel density measurement during deliveries: 690–800 kg/m³ for gasoline and 800–900 kg/m³ for diesel.

Tall aboveground tanks at depots and terminals use the flexible Mag-FLEX probe, covering 1.5 to 22 m in metal tanks.

Modules and console connectivity

TLS-450PLUS takes the USM 0332812-001 probe and sensor module, the UIOM 0332813-001 input/output module, the 0333564-001 relay module and RS-232/RS-485 interface modules.

The console connects over Ethernet, RS-232, RS-485 and USB, and the QuickServer MODBUS/BACnet gateway passes tank data to building automation systems.
