Installation Instruction
1. Location Selection
The location selection of the gas detection transmitter is essential to achieve the best detection results. In
the selection of location, we need to consider the following factors: the density of gas in a leaking point,
proportion of target gas, the impact of surrounding buildings, condition of production equipment, wind direction
and annual meteorological conditions and even the location of windows and doors in an indoor environment.
We provide the following suggestions for your reference:
A. Maintain a proper distance between the detector and the possible gas leaking point. It would react too
fast or too frequent if the distance is not enough, which may paralyze people's mind.
B. The detector must be located in the downwind of the possible leaking point.
C. If installed indoor, but the source of the leak is outdoor, the detector must be installed at the air inlet.
D. Determine the height according to proportion of target gas in air.
E. Determine the quantity of detectors according to the condition of possible leaking point, frequency
of staff attendance and time of stay as well as the economic effect.
F. Consider to increase quantity of inspection point if the equipment is old.
G. Protect the detector from radiation of high temperature heart source. Environments of both
very high temperature and very low temperature will affect the result and lifespan of the detector.
