3.1 Selecting a Location
Factors such as air movement, gas density in relation to air,
emission sources and environmental variables affect correct
sensor location.
Air movement by fans, prevailing winds and convection should
be carefully evaluated to determine if a leak is more likely to
raise gas levels in certain areas within the facility.
Vapor density of a gas determines if it will rise or fall in air when
there are no significant currents. Lighter than air gases should
have the detector mounted 12 to 18 inches (30 to 45 cm) above
the potential gas leak, and heavier than air gases should be this
distance below the potential gas leak.
The Universal Series of gas detectors are designed for
rugged service in the field. However, sensors should
always be protected from environmental damage from
water, snow, shock, vibration and dirt.
