FlexiMet WX 2 System

A high quality weather station that is easy to install for immediate accurate wind and weather measurement. Wi-Fi connectivity enables data to be viewed over the internet and/or locally on PC.

The system measures a wide range of weather parameters; wind speed and direction, temperature, relative humidity, dew point and barometric pressure using the Gill MetPak.

FlexiMet WX 2 System comprises

  • SpaceLogger W8 Wireless data logger including SD card
  • Connection to WeatherFile.com website
  • Junction Box
  • Power supply unit (5V)
  • Power supply unit (12V)
  • MetPak weather station
  • Mounting mast
  • 15m RS232 cable between sensor and data logger

What's In The Box?

The MetPak sensor used in this system has an RS232 output and has a cable distance of 15 metres. If cabling distances are longer than this we can quote as required.

The sensor is linked with the RS232 cable to our SpaceLogger W8 Wireless data logger. The SpaceLogger W8 Wireless data logger date and time stamps the data storing it locally on the SD card from which it can be transmitted over the local Wi-Fi network onto our WeatherFile.com website or to PC. This gives the flexibility of being able to view the data locally on PC and/or remotely through the Weather-File website. If no local Wi-Fi network is available the data can be transferred manually to PC using the SD card.

The Weather File website displays the data onto a compass rose and wind speed display that is updated in real time every 5 seconds. Full weather data is displayed in tabular form, updated every 10 minutes.

Long term data, including 10 minute averaged data, is stored on the SD card in a .CSV file that can be easily downloaded into Excel for later analysis and reporting.

The system comes complete with a 0.9m anodised aluminium mounting mast and mains plug power supply. 12V UK or World plug options are available.

Lightning Protection

All FlexiMet systems are supplied without lightning protection as standard. Should you require additional protection for your installation, please contact us for a quotation.
