What are the requirements for the installation height of a fixed combustible gas detector?

This issue is crucial.Fixed Gas DetectorThe installation height is corely dependent on gas density, which needs to be compared with air density for determination.
Core Installation Principles
Detectors for combustible gases heavier than air (such as liquefied gas) should be installed 0.3-0.6 meters above ground level.
Detectors for detecting flammable gases lighter than air should be installed 0.3-0.6 meters below the ceiling. Xi'an Flammable Gas Detector

Detectors for detecting flammable gases similar to air density should be installed at a height of 1.5 to 2 meters from the breathing zone.

Additional Installation Requirements
Ensure installation is away from strong air flow areas such as vents and air conditioner outlets to prevent concentration dilution.
The horizontal distance from the source of leakage (such as pipeline, valve connections) should not exceed 5 meters to ensure rapid detection of the leaked gas.Xi'an Wireless Gas Detector Manufacturer
During wall installation, the detector probe should face the direction of potential leakage and maintain an appropriate distance from the wall, without blocking the air intake.
