What's In The Box?

Product Overview

The WindSonic Option 1 sensor used in this system has an RS232 output and has a cable distance of 15m. If cabling distances are longer than this we can quote as required.

The sensor is linked with the RS232 cable to the WCU which date and time stamps the data storing it locally on the Internal SD card from which it is transmitted over the local Wi-Fi network onto the Weather File 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.

The Weather File website displays the data onto the wind speed and Direction display that is updated in real time every 5 seconds.

Long term data, including 10 minute averaged data, is stored on the SD card in a .CSV file. All historic data is downloadable from Weather File, selectable between dates.

The system comes complete with a 0.9m anodised aluminium mounting mast and mains plug power supply. 5V 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.
