​The tightness testing equipment for heating oil underground tanks and pipes includes the following items :

TODA Unit ITM TechnologiesTODA Unit allows the acoustic signals processing and the tightness testing management. 

Technical specifications :

  • Inputs : 2 acoustic sensors, pressure/vacuum, power supply 230 V
  • Ouputs : USB to Computer and 24V for vacuum pump, …
  • 1 pressure/vacuum transmitter (-1bar tot +1bar)
  • 1 earth terminal setting equipotential
  • Loudspeaker, Notebook, TODA-15© software installed for tightness testing

Pompe à vide - ITM Technologies

The vacuum pump integrate safety devices (pressure, temperature) and cuts off its power supply if necessary.

Capteurs de détection - ITM TechnologiesITM Technologies detection sensors offer exceptional performance. They make possible the detection of the smallest leaks which are invisible from the naked eye, and thereby prevent any undesirable pollution. Furthermore, the sensors are automatically identified when the connection is established. ITM Technologies sensors have a cable a minimal length of 10 meters.

Enrouleurs de câbles de détection - ITM TechnologiesThis storage box is made to contain every tools needed for thightness tests (acoustic sensors, tools,…).

Équipement non atex ITMControl equipment is quickly deployed on site.

Equipment is quickly ready to perform tanks and pipes tightness test.



​This equipment is designed to test the inner wall of tanks and pipes containing heating oil   

  • Cylindrical tanks 
  • Single or dubble walled tanks (internal wall)

  • Empty tanks or filled with fuel 
  • Pipes associated to tank

ITM TODA-15 acoustic method

The ITM TODA-15 testing method combines depressurization (vacuum) of tested components (pipes, tanks, accessories) with acoustic detection of “leak noise” in case of tight defects. The depressurization is the dynamical element which generates the emission of turbulences in non-tight areas. The “leak noises” (turbulences) are detected thanks to the right position of the sensors in the controlled Underground Storage Installation (Pipes, tanks (UST). The ATEX sensors are connected to the electronic interface TODA Unit. It enables the acoustic signals processing, the tightness testing and monitoring. The ITM TODA-15® testing method is mainly used in Storage Installation working under atmospheric pressure.

​Advantages of ITM non ATEX equipments :

Time saving

Everything is integrated in one equipement: therefore, the trips back and forth between the tank and the vehicle are very limited, and the material deploys and folds very quickly.

Performances - Reliability

  • The TODA-15 © acoustic method detects leaks of 15/100 mm located on piping far from 25 m to the sensor (located in the tank), identify the problematic equipment, and most of the time locate it very precisely.

  • Intuitive listening – The ITM acoustic sensors allow to identify more easily the origin of the  leaks

  • Computerized Management

    • Automatic management of deadline verifications.

    • Traceability and complete replay mode of the test.

    • Flexibility and multifunctionality of a computer.

  • Quick tests

    • Tank and associated piping tested simultaneously.

    • No need to disconnect the pipes from the tank.

    • Tests made with the fuel contained in the tank (10% to 90%).

Working comfort

  • Have a comfortable workstation

  • The excellent sound quality can be hear from integrated speakers to ensure greater freedom of movement on the worksite. 

  • Computer-assisted tightness tests allows printing , recording and replay mode. 

  • The computer software also makes it possible to control the vacuum pump and the automatic stop system.

Technology without know-how is insufficient. That’s why we offer tailored training for organizations wishing to deepen or acquire knowledge of this very specific profession.

Training related to TODA software: the TODA software is very user-friendly, training is nonetheless integrated; it covers all the features and recommendations to get the most out of it.

Some parts of the equipment are inseparable from specific learning and procedures, the training program also incorporates this aspect.

Legal recognition

ITM technology and its evolutions have been tested and approved by several organizations in several countries:

  • CORCON according to EPA requirements



  • SGS

These awards enabled ITM to obtain the necessary approvals from the different ministries to carry out its control missions.
