Sensor Assembly Continued
Please note: On the edge of the wind direction sensor there are the letters
N, E, S
&
W
representing the four cardinal directions. When installing the weather station
in your chosen location, it’s vital to ensure that the sensor suite is properly oriented
otherwise the wind direction readings will be incorrect. It’s also important to make
sure that the sensor suite is level – please use the bubble level to verify this.
Choosing Your Location
The ClimeMET CM2026 uses a fixed sensor-suite, which ensures that the system
is straightforward to install and requires low maintenance. As all of the sensors
are part of one unit, choosing the location to install the system can have a
significant impact on some of the parameters that the station will measure. It
generally won’t be possible to attain a scientific-standard installation with a fixed
sensor-suite, so you may want to compromise depending on which readings are
of most-interest. Please consider the following:
Air Temperature is typically measured at 1 to 1.5 Metres above ground level.
The shield covering the temperature sensor ensures that the sensor itself is
shaded and ventilated, which will maintain the accuracy of the temperature
readings. A general rule for achieving the best accuracy is keeping the
station at twice the distance of any nearby object's height, so for example
20ft away from a 10ft tree.
Rainfall is normally measured at around 30cm above ground level. At
elevated heights, higher-wind speeds will have an effect on the catchment
of rainfall so readings may be reduced. Further down the line, the rain
collector may also need to be cleared if any leaves or debris create a
blockage, so it’s worth considering the accessibility of the station
beforehand.
The optimal height for wind speed measurements is around 10 metres
above ground. This will typically not be possible for residential installations,
so it’s often advised to mount alongside a chimney or existing mast if
available. If doing so, try to have a clearance of at least a metre in height
between the weather station and roof line.
