A high quality weather station that is easy to install for immediate accurate wind and weather measurement, complete with display to view data locally.
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.
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 IP65 rated WS-15A Display Unit providing a clear digital readout of wind speed and direction plus a wind direction arrow with cardinal points. Temperature, pressure, relative humidity and dew point are also displayed. The display enables set-up of an optional wind speed alarm and provides an RS232 data output to connect to a SpaceLogger W10 or SpaceLogger W8 Wireless data logger or PC.
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.
All FlexiMet systems are supplied without lightning protection as standard. Should you require additional protection for your installation, please contact us for a quotation.
