Tips: Installation of Fixed Combustible Gas Detector

The combustible gas detector is used for flammable gas leak detection and alarming. When the combustible gas leaks and the detector monitors that the gas concentration reaches the set critical point, the flammable gas detector will sound an alarm to remind the staff of taking measures, to prevent explosions, fires, and poisoning accidents, thus ensuring safe production. Once fixed combustible gas detector is installed in place, its position is not easy to change. Therefore, something should be noted before installing the detector.

  • First of all, it is necessary to find out the place to be monitored where may be leaking points or prone to gas leakage, such as the interface of the pipeline, etc., and analyze the leakage pressure, direction and other factors.
  • It also needs to judge the direction of leakage of combustible gas when a large number of leakage occurs according to the air flow direction, wind direction and other specific factors on site.
  • According to the density of the leaked gas (greater or less than air) and the trend of air flow, the downstream position of the gas flow can be considered as the initial installation point.
  • Figure out the leakage state of the leak point, micro leak or spray-like leak. If it is micro leakage, the combustible gas detector should be installed closer to the leakage point. If the leakage is spray-like, it should be installed slightly away from the leak point.
  • The installation height of the outdoor gas detector can be selected according to the density of the measured gas. A very important thing to understand is that the detector should be installed on the downwind side.
