Mounting MetPak II
MetPak II uses a U-bolt mounting clamp suitable for attaching to a vertical pipe
with a diameter of 25-50mm. When mounting MetPak II, consider the position,
orientation and alignment of the unit.
Position
It is the responsibility of the customer to ensure that the MetPak II is mounted in a
position clear of any structure, including the mounting post, which may obstruct the
airflow or induce turbulence.
CAUTION. Do NOT mount the MetPak II in close proximity to high-powered
radar or radio transmitters. A site survey may be required if there is any
doubt about the strength of external electrical noise.
The temperature and humidity probe is mounted inside the radiation shield as
shown in Figure 3.
Orientation
Normally, the MetPak II is mounted on a vertical pole, ensuring a horizontal
Measuring Plane (see Figure 9).
For indoor use the unit may be mounted with the Measurement Plane set to any
required orientation.
Alignment
The MetPak II should be aligned to point to North, or any other reference direction
–for example, the bow of a boat.
There are two arrows, a coloured rectangle, and an alignment notch to aid
alignment.
Note.
It is usually simpler to work first with a compass at ground level and identify a
suitable landmark and its bearing.
