Gas characteristics

Different combustible gases have different densities, such as hydrogen, which is lighter than air and will diffuse upwards. The detector should be installed above the release source; Heavier than air, such as liquefied petroleum gas, is prone to accumulate in low-lying areas, and detectors should be placed near the ground. At the same time, the gas diffusion rate and range should be considered to determine the appropriate detection range.

Release source location

Clearly identify the possible sources of combustible gas release, such as valves, flanges, pipeline interfaces, etc., and reasonably distribute points within a certain distance from the release source to ensure timely detection of leaked gas. For multiple release sources, it is necessary to comprehensively consider their distribution and form an effective monitoring network.

Venue environment

The ventilation conditions of a place affect the distribution of gases. Good ventilation promotes rapid gas diffusion, and detectors can be appropriately reduced in quantity and adjusted in position; Areas with poor ventilation need to increase the density of distribution points. In addition, environmental factors such as temperature and humidity may also affect the performance of the detector. It is necessary to choose products that are suitable for the corresponding environment and install them reasonably.

building structure

The spatial layout, height, and shape of a building can all affect gas flow. For example, gases may stratify in tall spaces, requiring detectors to be installed at different heights; Gas diffuses along the narrow channel, and detectors should be evenly arranged along the channel.

Common Misconceptions

Insufficient or excessive number of distribution points

Insufficient deployment points prevent comprehensive monitoring, leaving detection blind spots; Excessive amounts can increase costs and may lead to false alarms due to interference. The number of deployment points should be scientifically determined based on the size of the location, the number of release sources, and other factors.

Neglecting installation height

Not selecting the appropriate installation height based on gas density resulted in the detector being unable to effectively detect leaked gas.

Not considering maintenance convenience

Installing the detector in a difficult to access location is not conducive to daily maintenance, calibration, and replacement, and affects its long-term stable operation.
