Field Installation
6.1. Site Selection
Careful consideration needs to be taken when selecting the air quality monitoring site.
The key AQM site selection considerations are:
1.
Placement
- local walls, buildings, trees etc. will affect the gas concentrations at a micro-spatial
level. Please refer to the discussion of placement guidelines written by the EPA in document
40
CFR 58, Appendix E
.
2.
Access
– the AQM60 will require servicing and calibration. Therefore the site should be easily
accessible for personnel to undertake calibration without placing themselves at risk. The site may
also need to be secure so care is needed to ensure both accessibility and security are taken into
account.
3.
Environmental -
the installation site should be selected to minimize exposure to
Dust (avoid sites where windblown soil and debris is present)
Vibration (avoid support structures close to trains, trams, heavy trucks)
Weather extremes (avoid solar exposure, wind chill)
Power outages (fit a UPS if power outages are expected)
4.
Interferences
- the site should be selected to minimize exposure to interferences from point
sources such as industrial plant, restaurants, swimming pools, etc unless the purpose is specifically
to monitor such sites. If in doubt please contact Aeroqual.
6.2. Mounting
The AQM60 unit is approximately 50-60kg and therefore needs a foundation to support this weight.
The dimensions of the AQM60 are as follows:
Dimensions (H x W x D)
Enclosure and TMS - 850 x 460 x 310 mm
With brackets and cowlings - 900 x 555 x 400 mm
Height with PM inlet installed - 1300 mm
The AQM60 comes with a pole mounting kit. This consists of two sets of U bolts with 4 nuts and 4 spring
washers. This provides flexibility as to where the unit can be mounted. The U bolts specifications are 3-1/2
PIPE X 3/8 304 U BOLT.
If a sample inlet extension is required, use inert tubing such as PTFE or PFA smooth wall tubing to minimize
contamination and reaction of the sample line. Maximum recommended length is 5 m.
