1. Introduction
MetPak Base Station is a compact multi-sensor instrument that measures the most
essential weather parameters. It also provides a data collection system that allows
customers to add their own selection of sensors to meet local requirements. A Gill
Instruments Ultrasonic Sensor can be used to measure wind speed and direction.
Temperature and Humidity are measured and Dewpoint calculated using an
industry standard probe housed in a naturally aspirated radiation shield. Barometric
pressure is measured using an industry standard sensor.
The Wind Sensor can be chosen from a 2 axis WindSonic Option 2 (white),
WindSonic M Heated, WindObserver 70 enhanced heated or a 3 axis WindMaster
or WindMaster Pro.
The MetPak Base Station combines all the instrument data into a single combined
data string. This may be configured for digital ASCII RS232/RS422/RS485 (2 wire
point to point) and digital SDI-12 outputs.
The instrument uses a rugged mounting clamp that attaches to any vertical pipe up
from 30mm to 58mm diameter.
The Base Station electrical Hub box comes with a pre-installed 10 Metre cable to
connect to a Gill Wind Sensor. There is one cable gland allocated to provide entry
for termination of other sensors and one cable gland for data/power cables.
A Heater Interface box (optional accessory) allows for termination of the Base
Station 10 Metre cable to a heated Wind Sensor and Heater power supply.

1.1 Principle of Operation
1.1.1 Wind Speed and Direction Sensor
The MetPak Base Station can be used with Gill 2axis (WindSonic or
WindObserver) or 3 axis (WindMaster or WindMaster Pro) wind speed and
direction sensors. They are connected via the supplied RS422 10 Metre lead. The
sensors measure the times taken for an ultrasonic pulse of sound to travel from the
North transducer to the South transducer, and compares it with the time for a pulse
to travel from S to N transducer. Likewise times are compared between West and
East, and E and W transducer.
If, for example, a North wind is blowing, then the time taken for the pulse to travel
from N to S will be faster than from S to N, whereas the W to E, and E toW times
will be the same. The wind speed and direction can then be calculated from the
differences in the times of flight on each axis. This calculation is independent of
factors such as temperature.

1.1.2 Radiation Shield
The Multi-Plate Radiation Shield protects temperature and relative humidity
sensors from error-producing solar radiation and precipitation. This shield relies on
a combination of plate geometry, material and natural ventilation to provide
effective shielding.
1.1.3 Temperature and Relative Humidity Sensor with
Dewpoint Output
The Rotronic HygroClip module is a complete instrument, with integrated
temperature compensation. Calibration data is maintained within the integrated
electronics. It provides digital output signals for Relative Humidity, Temperature
and Dewpoint to the MetPak Base Station Hub box.
Figure 2 Position of Temperature and Relative Humidity Probe in the Radiation Shield
1.1.4 Barometric Pressure
Barometric pressure output is provided by a solid-state device fitted on to the
circuit board in the MetPak Base Station Hub box. Vent to atmosphere is via a
Gortex filter which also protects the pressure sensor from the effects of wind and
rain.

2. 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 andWind 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.

Cabling (unused wires)
Any unused wires in the connecting cables should be connected to ground
preferably at the user equipment end.
Cabling protection
The Cable should be secured:
With cable clamps or equivalent at regular intervals such that the hub
box cable gland does not support the cable weight.
Away from the mounting bolts to prevent chaffing of the cable.
NOTE. Install appropriate strain relief support to the cable. If possible, pass the
cable through the mounting pole.
Earthing
To ensure correct operation and for maximum protection from lightning, a separate
lightning rod system is recommended to protect the system.
You can also earth the MetPak Base Station through its mountings or by
connecting a grounding cable (minimum of 6mm² copper wire) to a spare MetPak
Base Station metalwork bolt hole. Clean off any paint that might prevent a good
connection on the installation.
When you connect the communications cable ensure that the screen has a
connection to the hub box case.
The Junction Box accessory and Heater Power Interface Box have a plastic case,
hence ensure continuity of cable screens into and out of the boxes using the
common earthing terminals provided in the boxes.
Routing Cables through the Hub Box Glands
NOTE: The MetPak Base Station Hub Box cable glands contain spring loaded
metal leaves that are designed to make a ground contact with cables that have an
overall braid screen. Care is therefore required when inserting and removing
cables through the glands to prevent damage to the metal leaves.
