This gauge displays the average wind speed as reported by your Tempest Weather System.  The gauge face is 3.5” in diameter and inserts into a hand made walnut wood case. The wood case has a 15 degree flat spot on the bottom so it can sit on a shelf or desk and not roll off.  The Gauge face is made of a laser etched brass laminate with a red indicating needle in front of it.  The gauge range is from 0 to 90 Miles Per Hour in a logarithmic scale. Three triple A batteries (not included) will run this gauge for about a year and a half.


The value displayed by the gauge will be updated about every 2.5 minutes. This Gauge requires a WallGauge Gauge Data Transmitter (GDT) to be 20 feet away or closer and in clear line of site.  One GDT can source several gauges so if you already have a GDT in the room you can use that GDT to send data to this gauge.  


You must have a Tempest Weather System installed and connected to the WeatherFlow cloud for this gauge to work.  The GDT will run our Tempest Weather gauge app to communicate with the WeatherFlow cloud API.  During setup you will be required to enter an API key giving the GDT permission to connect to your weather data.


The Wood case may very in color as it is real wood and finished with a friction polish made up of Denatured Alcohol, Transparent Shellac, and Boiled Linseed Oil.
