TS-LS500 pipeline leak sensor

The statistics of the TS-LS500 Pipeline leak detection sensor learn the characteristics of each pipeline, avoiding possible configuration errors and ensuring unparalleled accuracy. This is an optional feature of the TS5 family of fuel management systems and is also available as a separate ELLD system. It includes an industry-first statistical pipeline leak detection feature for high-throughput sites.

Bright spot:

  • Automatically learn the precise characteristics of the pipeline.
  • No piping and length programming is required.
  • Can be used to monitor any pipe such as flexible, steel and/or fiberglass.
  • In combination with a submersible pump, it produces a pressure of 25 psi or more.
  • Automate 3.0 gph, 0.2 gph, and 0.1 gph pipe tests, as well as other pipe pressure tests.
  • Equipped with the industry's only statistical electronic pipeline leak detection function.
  • Actively shut down the submersible pump in the event of a leak.
  • Optional features of the TS5 Series fuel management system.
  • Can be used as a stand-alone ELLD system.
  • For rigid, flexible and rigid/flexible pipe configurations.
  • Intrinsically safe with explosion-proof options.
  • Dispenser handle isolation and turbopump interface pump control options.
  • Remotely access pipeline pressure, test, and alarm information.

  • Sensor port fittings: 2" American standard cone female thread (NPT).
  • Sensor material: anode aluminum body, stainless steel sensor.


  • Perform a 3.0 gph leak and pressure test every refueling cycle or 45 minutes. Actively shut down the relevant turbopump when the test fails.
  • 0.2 gph precision leak tests are performed monthly and 0.1 gph precision leak tests once a year during refueling thermal stabilization. Actively shut down the relevant turbopump (optional) if the test fails.
  • Perform pressurization, capture pressure, and other additional tests. Alerts only when a test fails.

Sensor kits

Intrinsically safe

For new installations that can use separate low-voltage lines. Use TS-420IB module.

  TS-LS500/2 Two-wire sensor kit
  TS-LS500/3 3-wire sensor kit
  TS-LS500/4 4-wire sensor kit

Explosion proof

For retrofit equipment where only one high-voltage line can be used. Use TS-420EXP module.

Model illustrate
  TS-LS500E/2 Two-wire sensor kit, explosion-proof
  TS-LS500E/3 3-wire sensor kit, explosion-proof
  TS-LS500E/4 4-wire sensor kit, explosion-proof
  • Note: TS-RLY modules are not required for turbopump interface (TPI) communication; Requires an FFS Smart Controller.
