Electronic Line Leak Detection

Electronic Fuel Leak Detection System for Fuel Pumps

Veeder-Root's electronic Pressurized Line leak Detection System uses patented measurement technology to test lines at full pump pressure for highly accurate 0.1 gph precision and 3.0 gph gross testing. Plus, two methods of installation give you options that will substantially reduce your costs.

Key Benefits:

  • Swiftcheck valve mounts directly into the mechanical line leak detector port
  • No need to break product lines
  • No sump or manhole reconstruction required for installation
  • Ideal for applications where there is no existing sump
  • Lower installation and maintenance costs
  • Tests lines at full pressure for greater accuracy than other pressure line leak detection systems
  • Automatic, precision 0.1 gph testing option eliminates the need for separate annual testing
  • Certified to exceed U.S. E.P.A. performance standards
  • Supports a wide-range of pump and pipe types; see Veeder-Root Line Leak Application Guide for details

All Veeder-Root Electronic Line Leak Detectors require a TLS-350 or TLS-4XX Console with installed system software versions shown in the table below.

LINE LEAK DETECTOR TYPE TLS-350 REQUIRED SYSTEM SOFTWARE TLS-4XX REQUIRED SYSTEM SOFTWARE
PLLD VERSION 7 OR HIGHER VERSION 1 OR HIGHER
WPLLD VERSION 12 OR HIGHER NOT AVAILABLE

Veeder-Root recommends that system software for the console be upgraded to the newest version when installing any new hardware. For TLS-350 Consoles, when installing Version 19 software and subsequent releases, PLLD and WPLLD must be specified and customer must upgrade to ECPU2 if not already installed. See Accessories/Upgrades section of price book or your local Veeder-Root authorized distributor for details.
