Leak Detection

Safety is the number 1 concern of most companies involved in the handling of petroleum fuels, and protecting the environment is a close second. The regulatory framework in both areas is getting progressively tighter, so if your business involves the production, transportation, storage, refining or consumption of fuels, you need to consider the possibility of a leak.

In some situations the potential source of a leak can be anticipated. A valve pit, an overfill containment or a low point sump is an ideal location for a fast acting fuel probe. Quickly knowing that fuel is accumulating in an unexpected area can be the key to avoiding a catastrophic accident or expensive clean-up.

Don’t make the mistake of thinking that a “slow” leak is a “small” leak. A slow leak results in a large spill if the detection system is too insensitive to detect leaks below a given threshold or below a certain percentage of flow. Far too many leaks are discovered when someone notices the smell of fuel, or after surface/below ground water has become contaminated.

Fuel Leak Detection System

nVent Thermal Management offers fuel leak detection solutions that will find leaks before they find you.

The nVent TRACETEK fuel leak detection system has these basic parts:


  • Sensing cables – these cables provide early detection of below ground or above ground “weeps and seeps” before they accumulate into large spills.  And the location is reported to the nearest meter.
  • Probes – these detect fuel floating on water or fuel accumulating in low spots like sumps or valve pits or on flat surfaces like pump pads. The probes react instantly to even a thin film of fuel and can be reset and reused and even “wet tested” if desired.
  • Sensor Interface Modules and Alarm Panels – these are designed to energise the sensor cables and probes, monitor their condition and report the existence and location of any leak detection to operators and other alarm and supervisor systems.
