Installation
MetPak Base Station has been designed to meet and exceed the stringent
standards listed in its specification (see Para 6.1).
2.1
Pre-Installation Checks
As with any sophisticated electronics, good engineering practice should be followed to
ensure correct operation:
Ensure the MetPak Base Station and Wind Sensor will not be affected by other
equipment operating locally, which may not conform to current standards, e.g.
radio/radar transmitters, generators etc.
Avoid mounting in the plane of any radar scanner – a vertical separation of at least
2m should be achieved.
When installing MetPak Base Station and Wind Sensor near radio transmitting
antennas, ensure that the mounting position fulfills the following minimum
separations (all round):
VHF IMM – 1m
MF/HF – 5m
Satcom – 5m (avoid likely lines of sight)
Use cables recommended by Gill (see Para 2.2.3). If cables are cut and re-
connected incorrectly (perhaps in a junction box) then EMC performance may be
compromised if cable screen integrity is not maintained.
Avoid earth loops – wire the system in accordance with these installation
guidelines.
Ensure that the power supply operates to the MetPak Base Station and Wind
Sensor specification (see Para 6.1) at all times.
Avoid turbulence caused by surrounding structures that will affect the accuracy of
the sensors such as trees, masts and buildings. The WMO make the following
recommendations. The standard exposure of wind instruments over level open
terrain is 10m above the ground. Open terrain is defined as an area where the
distance between the sensor and any obstruction is at least 10 times the height of
the obstruction.
Keep away from building exhaust vents, machinery and motors.
