The system responds to the distinctive ultrasound created by the leak.
The detectors pick up gas leaks at the speed of sound without having to
wait for the gas to accumulate and physically enter a point sensor head
(conventional point detector) or within a narrow beam (open path gas
detector). The acoustic detection method is thereby unaffected by
unknown factors such as wind conditions, gas dilution and leak
direction. The simulator can be accessed in a trial version on the
vendor’s Web site. Gassonicwww.gassonic.com/simulator+45.44.700.910
