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.
