To ensure optimal detection coverage of the ultrasonic gas leak detectors, it is important to have an indication of the ultrasonic background noise. Therefore, Gassonic A/S has developed a customised ultrasonic mapping meter. Gassonic A/S has wide experience and our trained engineers may assist clients performing the survey onsite. This will ensure optimal allocation and performance of the ultrasonic gas leak detection system. The background noise survey is typically done before installation but it may also be completed together with the commissioning of the detection system. READ MORE...

When detectors have been installed, system commissioning is performed to ensure that the total leak detection system will detect gas leaks in the entire area it is supposed to. During the commissioning, all Gassonic ultrasonic gas leak detectors are tested by means of artificial gas leaks simulated by means of compressed nitrogen.

When commissioning traditional gas detection systems (IR point sensors or open-path detectors), a calibration gas is injected directly into the sensor head to verify that the detector senses the gas correctly. This test will ONLY verify if the gas detector measures the gas concentration correctly, BUT IT WILL NOT give any indication whether the gas detector will EVER detect a gas leak just a few meters away from the gas detector!

When a Gassonic ultrasonic gas leak detection system is commissioned, it is tested by means of REAL gas leaks (nitrogen) in distances up to 12 meters 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 can assist clients in doing this.

Gassonic A/S provides detailed documentation of mapping surveys and commissioning in professionel reports customised for each individual customer.

Ultrasonic mapping reports document measuring results. Pictures and technical drawings will propose settings of and installation locations for each individual acoustic ultrasonic gas leak detector in areas of concern.

System commissioning reports will include measuring results as well as verification of leak detection coverage of all ultrasonic gas leak detectors tested with artificial leak test equipment.

Gassonic personnel performing on-site services has offshore safety courses complying with OPITO, NOGEPA and OLF approvals.
