Fixed RAWS
The FTS fixed RAWS is the international standard remote automated weather station used for fire weather monitoring in North America. It's a purpose-built system comprised of components and designed to inter-operate specifically with the interests of fire and fuels management agencies in mind. From the assembly of a new station at a remote location to yearly service and maintenance, the design of the FTS fixed RAWS shows our extensive 30-years of experience in the market.
- Every component meets or exceeds NFDRS/CFDRS standards.
- Approved, certified and serviced by RSFWSU.
- Pre-configured for fire applications and compliant with ASCADS database.

The Best Part Weighs Nothing
FTS customers know that our equipment is exceptionally reliable and built like a tank. But the most significant reason that more fire management professionals rely on FTS than any other vendor is the service and support. We really take care of our customers, and they know it. So much goes into making things extremely simple—from extensive documentation written by people who work with the same equipment in the field as our customers do, to our lifetime, toll-free technical support.
Wind speed and direction sensor
The SDI RMYoung Wind Monitor by FTS measures the ten-minute average wind speed and wind direction just prior to the hourly GOES transmission. The maximum wind speed (gust) over a 60 minute period as well as the direction from which the maximum gust came from is logged.
We have recently switched the standard wind sensors for the fixed RAWS to a dual wind/speed sensor made by R.M. Young, modified by FTS to output using the digital SDI-12 protocol. The fixed RAWS can still be configured with separate analog wind speed and wind direction sensors or even an ultrasonic wind speed/direction sensor.
Tri-leg Tower Mast
The mast of the tri-leg tower places the wind speed and direction sensor at a height of 20 feet (6.1m). Can be lowered for easy servicing of sensors.
RVT Antenna
Allows broadcast of voice alerts from an optional RVT Radio Voice Transmitter to any DTMF-capable radios up to one mile (1.6km). The RVT allows querying the station and receiving current weather conditions being monitored in real-time.
Air Temperature and Relative Humidity Sensor
Current air temperature and 10-minute average relative humidity are measured by the THS-3 sensor and logged.
Rain Gauge (Tipping Bucket)
The RG-T rain gauge measures precipitation in increments of .01 inch (0.254mm), each hour.
Solar Radiation Sensor (Pyronometer)
The SDI-SR-PYR solar radiation sensor measures the amount of sunlight exposed to fuels.
GOES “Yagi” Antenna
Transmits data to a GOES satellite.
Tri-Leg Tower
FTS' unique tri-leg tower provides a solid frame to mount sensors and other equipment. Anchored to the ground, it is able to withstand sustained 125 mph (201 km/h) winds without requiring setting in a concrete base.
Enclosure and Electronics
Made from durable heavy-gauge aluminum, the enclosure houses the Axiom F6 datalogger (which optionally contains a GOES transmitter and/or RVT Radio Voice Transmitter), one or more heavy-duty batteries, any other electronics, manuals, etc.
On top of the enclosure is mounted a GPS antenna, used by the GOES transmitter to reset the internal clock to insure that data is always transmitted during the allotted 10-second window.
Fuel Stick
The FS-3 fuel stick measures fuel moisture and temperature. It's an optional component, and not installed on every fixed RAWS.
Solar Panel
Most stations operate on a battery, which is recharged by a solar panel. A 20W solar panel is most common, but 10W and 50W panels can be installed instead.
Adjustable Leg
The three legs of the tri-leg tower are adjustable in length to permit the tower to be installed on uneven ground. The feet can be anchored with metal stakes, or rocks can be piled on top of the feet.
