Veeder-Root TLS-350PLUS Automatic Tank Gauge (Legacy Console)

Name: Veeder-Root TLS-350PLUS Legacy Tank Gauge – Datasheet & Quote
Brand: Veeder-Root
SKU: TLS-350PLUS

Description

Legacy modular tank gauge for existing retail and commercial sites

The Veeder-Root TLS-350PLUS is an earlier-generation automatic tank gauge console offering in-tank inventory, leak detection and compliance for retail and commercial operations. This page is for sites that already run TLS-350 series equipment and need to identify consoles, modules and software options. It is a legacy product, so please read the status note below.

The datasheet in our library is the 2021 edition. Veeder-Root’s website presents the TLS-450PLUS and the TLS4 and TLS4B as its current automatic tank gauges, with an upgrade page for the TLS-450PLUS, and its obsolete-product notifications page lists an End of Sale notice for TLS-350 Series ATG systems (in the 2021 list) and an End of Life notice for TLS-350 systems in California (2025). Supply of consoles and modules therefore depends on remaining stock, and we confirm availability per enquiry.

Using the datasheet for spares and migration

The datasheet separates low-power compartment interface modules (probes and sensors) from high-power modules (relays and controllers), and lists the sensor part numbers each module serves. It also lists the communications and memory expansion modules and notes that a memory expansion is required for software version 27 or higher with more than eight tanks or with BIR on manifolded tanks. Features such as BIR and variance analysis are standard in the TLS-350R and upgradeable in the TLS-350PLUS.

For a new site, Veeder-Root’s current consoles are the TLS-450PLUS, TLS4 and TLS4B on our site. Mag Plus, Mag-FLEX and many sensors remain compatible with TLS-350 series consoles through the 4-input probe module, as the probe datasheets state.

Status and what to confirm

Legacy status: the manufacturer’s end of sale notice for TLS-350 series systems applies; confirm that modules or consoles can still be supplied.
Console model (TLS-350PLUS, TLS-350R or PC-350 variants), software version and installed modules.
Whether the site is better served by replacing the console with a TLS-450PLUS (the manufacturer’s own upgrade path).

About brand

Veeder-Root fuel tank gauging and leak detection

Veeder-Root is a fuel management specialist based in Simsbury, Connecticut, founded in 1866 and part of Vontier. It is best known for TLS automatic tank gauge consoles, Mag Plus magnetostrictive probes, interstitial and sump sensors for leak detection, and the EMR4 electronic meter register.

Typical applications

These products are used at petrol stations, fuel depots and airports to measure product level, water and temperature in underground and aboveground tanks, to monitor containment and to support inventory reconciliation and regulatory leak tests. Datasheets give probe lengths, product compatibility, communication options and approvals for each model, so the correct configuration can be defined before a quotation is requested. Where a model is discontinued, we say so on the product page.

Sourcing Veeder-Root products in Oman

Seven Star LLC lists Veeder-Root models from the maker's published datasheets and prepares quotations on request. Send the tank type, product, probe length and site requirements and we will check them against the datasheet.
