Gas leak detection is the process of identifying potentially hazardous gas leaks by sensors. Additionally a visual identification can be done using a thermal camera These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected.
The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks. LDS provide alarms and display other related data to the pipeline controllers to assist decision-making. Pipeline leak detection systems can also enhance productivity and system reliability thanks to reduced downtime and inspection ...
As well as airbags, the air conditioning system, fuel system, and exhaust system require testing for leaks. Pacemakers and catheters have to be tested for efficacy and longevity. On planes, tracer-gas leak testing is used to quickly and safely locate fuel leaks, [3] as well as to check oxygen distribution devices and cabin pressurization systems.
A detector for propane is best placed down low near the floor, as propane is heavier than air. [3] A detector for natural gas (city gas) is best placed up high, near the ceiling. [3] Some detectors can detect both natural gas or propane, but this requires a compromise location. [4]
The main objectives of the fire and gas system are to: Detect at an early stage the presence of flammable gas using gas detectors. Detect at an early stage hazardous liquid spills. Detect incipient fire and the presence of fire using fire detectors. Provide automatic and/or facilities for manual activation of the fire protection system as required.
An open path detector usually costs more than a single point detector, so there is little incentive for applications that play to a point detector's strengths: where the point detector can be placed at the known location of the highest gas concentration, and a relatively slow response is acceptable. The open path detector excels in outdoor ...
