6. Installation
6.1 Orientation
During operation, the IRGASON should be leveled and pointed into the prevailing wind to
minimize flow distortions from the instrument arms and other supporting structures. Leveling
can be done using the leveling bubble on top of the instrument block. In the proper orientation,
the product label will read right-side-up, with the upper arm (source) of the gas analyzer directly
above the lower arm (detector).
If the IRGASON is to be used in a marine environment, or in an environment where it is exposed
to corrosive chemicals (for example, the sulfur-containing compounds in viticulture), attempt to
mount the IRGASON in a way that reduces the exposure of the sonic transducers to saltwater or
corrosive chemicals. In marine or viticulture environments, the sonic transducers are expected to
age more quickly and require replacement sooner than a unit deployed in an inland, chemical-
free environment.
NOTE:
The ingress protection rating of the EC100 is not optimal for marine environments or other
environments in which the enclosure may come in contact with corrosive chemicals
(viticulture or agriculture, for example), as components within the enclosure are at higher risk
to exposure to these substances. However, instruments with EC100 enclosures are being used
in these environments with additional precautions. If the instrumentation is intended for such
an environment, contact Campbell Scientific for guidance before deploying the instrument.
