3.7 Description of Gas Leak Detection Using Ultrasound
A high pressure gas leak is a broadband continuous phenomenon. This gas leak ultrasound signature is detected in the presence of
other ultrasound noise sources using advanced detection algorithms. The detection algorithms differentiate between leak signatures
and typical noise source signatures in both time and frequency domains.
3.8 Mounting Accessories and Flexibility
The Searchzone Sonik detector is supplied with the Standard Adjustable Mounting Bracket that can be simply installed prior to the
fitting of a Searchzone Sonik detector. The 3-axis adjustment allows the detector to be aimed precisely and has graduated angles
marked on the adjustments. The Standard Adjustable Mounting Bracket allows simple fixing onto a range of surfaces as well as poles,
struts, plates and other plant infrastructure. It is manufactured from high quality Stainless Steel.
