What's In The Box?

PLEASE NOTE: For cable lengths over 20m a WindSonic Option 2 sensor with RS422/485 output is required - please contact us for a quotation.

Product Overview

The sensor is linked with the RS232 cable to our IP65 rated WS-15A Display Unit providing a clear digital readout of wind speed and direction plus a wind direction arrow with cardinal points. The display enables set-up of an optional wind speed alarm and provides an RS232 data output that connects to a 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 Weather-File website or to PC. This gives the flexibility of being able to view the data locally on the WS-15A Display 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.

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. 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.
