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 (acoustic) 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 (acoustic) gas leak detection system is commissioned, it is tested by means of REAL gas leaks (nitrogen) in distances up to 20 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.
