SDT 270 Tank Testing

Over time, the structural integrity and airtightness of underground storage tanks and other sealed compartments can deteriorate — or, in some cases, may never have been fully airtight in the first place.

For this reason, tightness testing is a critical maintenance activity, helping to identify leaks early and prevent unnecessary losses and environmental harm.

Undetected leaks from underground storage tanks can lead to contamination of surrounding soil, groundwater and surface water, as well as the avoidable loss of valuable product. Regular testing is therefore essential to ensure compliance, safety and environmental protection.

Our Method

Our ultrasonic underground tank testing method allows the tightness of both the tank and associated pipework to be assessed simultaneously, without the need to open the manhole. This non-intrusive approach minimises disruption while delivering accurate, reliable results.

Ultrasonic tightness testing works by capturing and amplifying the sound generated by leaks when the tank is placed under partial vacuum. Two highly sensitive sensors are used during the test: one positioned within the liquid and the other above the liquid surface.

Using advanced SDT ultrasonic equipment, background noise within the installation is first measured to establish a reference value, expressed in dBµV. The tank is then depressurised, and measurements from each sensor are continuously monitored and compared against this reference.

Diagnosis

All events recorded during the test are displayed in real time via a histogram that tracks data from both sensors. Measurement data can be reviewed directly on the SDT device, providing clear insight throughout the process.

The final diagnosis is confirmed by the operator, who also audibly verifies the presence of any leak by listening to the ultrasonic signal. Recording durations for both measurement data and audio files can be tailored to suit operational requirements, with full flexibility for pauses or adjustments during testing.

This adaptable and precise testing approach ensures reliable leak detection while maintaining minimal operational impact.
