The TRV, Upgrade Weather Station has a built-in 2.4 GHz spread spectrum radio module with 128-bit data encryption (XBeePro). The unit has no moving parts and is ideally suited for use wherever reliable, maintenance free operation over a wide operating range under adverse operating conditions is required. The unit is built with a metal housing to offer some protection from electromagnetic interference. The TACMET II TRV, Upgrade Weather Station is painted CARC tan. 2.2 Specifications PERFORMANCE Wind Speed Range Accuracy * Resolution Wind Direction Range Accuracy * Resolution Temperature Range Accuracy Resolution Relative Humidity Range Accuracy Resolution Barometric Pressure Range Accuracy Resolution 0-65 m/s (0-145 mph) 0.5 m/s (1.1 mph) 5% 0.1 m/s (0.22 mph) 0 to 360 5° @ wind speeds > 2.2 m/s (5 mph) 1 -40° to 60C (-40° to +140F) 2C ( 3.6F) @ WS>2.0 m/s (4.5 mph) ± 0.1°C 0 to 100% 3% 1% 500 to 1200 hPa (14.75 to 35.50 in Hg) 0.40 hPa (±0.01 in Hg) 0.1 in Hg MTBF 80,000 hours * This accuracy is maintained when the sensor is within 10 degrees of vertical. 102902-9800 Operation Manual ISO 9001:2015 Certified 7 Revision B, 10/3/2024 ELECTRICAL Measurement Format Measurement Rate Operating Frequency Signal Output Power Requirements Two orthogonal axis, North-South and East-West Approx. 2 Hz each axis 40 kHz RS232 @19.2 K baud (see section 5.0) 9 - 36 Vdc: 100 mA draw @ 12 Vdc PHYSICAL Size Weight Mounting Finish Color 12.25 inches (31.1 cm) x 4 inches (10.15 cm) dia. 5.5 lb.

The TACMET II, TRV, Upgrade Weather Station is installed on the Met One P/N 102709 pre-wired Quick Mount. The keyway in the connector on the base of the TACMET II, TRV, Upgrade Weather Station is matched to the keyway on the mount. Attach the TACMET II, TRV, Upgrade Weather Station to the 102709 Quick Mount by inserting it into the top of the mount, aligning the latch springs with the clips on the bottom of the sensor. It may be necessary to rotate the TACMET II, TRV, Upgrade Weather Station 180° to allow the keyway to seat properly. When the sensor is properly seated in the mount, attach the latch springs to the clips on the sensor and snap them down to lock the sensor in place. The TACMET II, TRV, Upgrade Weather Station is supplied with an internal fluxgate compass to automatically orient the wind direction data to magnetic North. True North is calculated by the sensor if a value for the magnetic declination is input to the sensor (see Appendix A). It is not necessary to manually align the TACMET II, TRV, Upgrade Weather Station towards North. 4.0 Input/Output Connections The sensors' pin designations are as follows: PIN FUNCTION A Power and RS232 Ground B +9 to +36 Vdc Power Input C N/C D N/C E N/C F N/C G RS232 Receive Data H RS232 Transmit Data I N/C J N/C Radio Antenna Connector: TNC Jack 102902-9800 Operation Manual ISO 9001:2015 Certified 9 Revision B, 10/3/2024 5.0 User Interface The internal serial port works in parallel with the radio. The unit is set for polled operation. The output of the TACMET II, TRV, Upgrade is a serial data stream. Typically, the output is set for 19.2k baud (N/8/1) and outputs the data string when polled. The data can be viewed, displayed, and logged using Met One AWeather Software. An example of the output format is shown below: <STX>R S0011 000.6 102 +077.1 055 29.77 63<EOT> The string consists of eight fixed length fields each separated by a space (0x20) character. Each data field contains leading zeros, temperature is preceded by a plus or minus sign. Field 1: Start of transmission character <STX> immediately followed by an R Field 2: Serial number of the sensor (Snnnn) Field 3: Wind speed data in miles per hour (nnn.n) Field 4: Wind direction data in degrees (nnn) Field 5: Temperature data in degrees Fahrenheit (+/-nnn.n) Field 6: Relative humidity data in percent (nnn) Field 7: Barometric pressure data in inches of mercury (nn.nn) Field 8: Two digit Checksum two-digit checksum immediately followed by an end of transmission character (nn<EOT>). The Checksum is the Twos Complement (Negated) of the 8 bit sum of all the characters in the output including the <STX> character to start the message and the ending <EOT> character (not including the Checksum itself). The Checksum is inserted into the string before transmission. The polling string is set at the factory during manufacturing. The string is set to the sensor serial number using the terminal commands. Should it become necessary to re-set the polling string in the field, please refer to Appendix A for instructions on how to enter the terminal command mode and the "ST" command. 102902-9800 Operation Manual ISO 9001:2015 Certified 10 Revision B, 10/3/2024 6.0 Calibration A zero wind speed check can be done by covering the sensor with a thick plastic bag sealed beneath the sensor. The wind speed should read zero, and the wind direction will bounce around. WS, WD, temperature, relative humidity and pressure should be checked by co-location with a reference sensor. For formal calibration, the unit needs to be returned to the factory. The sensor requires a wind tunnel for WS/WD calibration. Met One Instruments, Inc. can provide NIST traceable calibration in our wind tunnel. Please contact the factory for details. 7.0 Maintenance Because the sensor has no moving parts to wear out, periodic maintenance is not required. In extremely corrosive environments, the condition of the connector used to mount the sensor should be checked. In harsh environments, the transducer screens should be checked for dust or sand buildup. Should the transducer screens need to be cleaned, with the unit upright, brush the transducer screens with a short, medium to firm bristle brush. There are no adjustments or user repairable parts located inside the sensor. 102902-9800 Operation Manual ISO 9001:2015 Certified 11 Revision B, 10/3/2024 Appendix A Terminal Mode Commands Connect to a computer running a terminal emulator program like Putty at 19200, N, 8, 1.

If the sound is traveling in the direction of the wind, the transit time is decreased. If the sound is traveling in a direction opposite the wind, the transit time is increased. This principal is well known and is the basis of most sonic anemometers. Temperature / Humidity The temperature sensor in the P/N 102902 TACMET II, TRV, Upgrade uses a precision single-element thermistor. This provides a highly accurate and stable temperature reading. The resistance value is 10K ohms at 25°C. This allows the TACMET II to directly interface with the temperature sensor without additional electronics; sensor compensation is handled through software. The relative humidity sensor is a capacitive element sensor. It has a linear voltage output connected directly to the TACMET II, TRV, Upgrade microprocessor. The humidity sensor element's construction provides excellent resistance to wetting, dust, dirt, oils, and common environmental chemicals. A heavy contaminant layer of dirt will slow down the sensor's response time because it will take longer for water vapor to equilibrate in the sensor. Barometric Pressure The P/N 102555 barometer uses proven silicon sensor technology with microprocessor-based signal compensation, eliminating the need to insulate or temperature-regulate the barometer. The P/N 102555 has a pressure range of 14.75 to 35.50 in Hg (500 to 1200 hPa). The P/N 102555 has a TTL output that reduces the power consumption of the barometer to 33 mW. The accuracy of the sensor is ±0.4 hPa (0.01 in Hg) 102902-9800 Operation Manual ISO 9001:2015 Certified 15 Revision B, 10/3/2024
