1. System commissioning after installation.
  2. Regular inspection.

Gassonic A/S provides worldwide system commissioning support. Regular inspection is done by qualified plant personnel.


System commissioning after installation is performed to ensure that the leak detection system can provide gas leak detection coverage in the entire area it is supposed to. During the commissioning, all Gassonic ultrasonic (acoustic) gas leak detectors are tested by means of artificial gas leaks simulated by means of compressed nitrogen.

During the commissioning of traditional gas detection systems (IR point sensors or OpenPaths Detectors), a calibration gas is injected directly into the sensor head to verify that the detector detects the gas correctly. This test will ONLY verify if the gas detector measures the gas concentration correctly, BUT IT WILL NOT give any indication that the gas detector will EVER detect a gas leak just a few metres away from the gas detector!

When a Gassonic ultrasonic (acoustic) gas leak detection system is commissioned, it is tested by means of REAL gas leaks (Nitrogen) in distances up to 20 metres away from the detector. This will verify the leak detection performance of each detector. Gassonic A/S has great experience in commissioning of ultrasonic gas leak detection systems, and the company offers this as an on-site service to the customer.


Regular instection

After the commissioning of an Gassonic ultrasonic (acoustic) gas leak detection system, the system only needs a regular inspection every 6-12 months. The inspection consists of a visual check of the detector to ensure that the wind-screen is intact. After the visual inspection, each detector is tested by means of the fully traceable Portable Test and Calibration Unit, the Gassonic 1701.

This test will ensure the detector has the same leak detection sensitivity as it had at installation and commissioning.
