An internal heater reduces moisture forextended bearing life. This sensor is usually used in conjunction with the 191 Cross arm Assembly. The sensor may be used with a translator module, or used directlywith a variety of data loggers.1.2 The Sensor Cable has a quick-connect connector with vinyl jacketed, shielded cable.Cable length is given in -XX feet on each cable part number. A 1953-XX cable isused with translators having terminal strip connections.Table 1-1Model 010C Wind Speed Sensor SpecificationsPerformance CharacteristicsMaximum Operating Range 0-60 meters/sec or 0-125 mphStarting Speed 0.27 meters/sec or 0.6 mphCalibrated Range 0-50 meters/sec or 0-100 mphAccuracy ±1% or 0.15 mphTemperature Range -50︒C to +85︒CResponse Distance constant less than 5 ft of flow**The distance traveled by the air after a sharp-edged gust has occurred for theanemometer rate to reach 63% of the new speed.

External heater and power supply for extreme low temperature operation.B. Ice Skirt for extreme icing environments.C. Aluminum cup assembly.2.0 INSTALLATION2.1 The 010C Wind Speed InstallationA. Mount the cup assembly and secure with the Allen head set screw, check to seethat the cup assembly rotates freely.B. Install the sensor in the end of the Model 191 Crossarm Assembly (the endwithout the bushing).C. Tighten the locking set screw. Do not over-tighten. Apply a small amount ofsilicone grease to set screws to prevent freezing in adverse environments.D. Connect the cable assembly to the keyed sensor receptacle and tape it to themounting arm.2.2 WiringA. The cable assembly contains five wires. Typical wiring hookup is shown inFigure 2-1.No Connection White/Brown ShieldElectrical ConnectorView looking at connector pins. (Pins are also identified on connector).2.3 Lightning ProtectionA. Weather sensors are sensitive to direct or nearby lightning strikes. A well-grounded metal rod or frame should be placed above the sensor installation. Inaddition, the shield on the signal cable leading to the translator must beconnected to a good earth ground at the translator end and the cable routeshould not be vulnerable to lightning.3.0 OPERATIONAL CHECK-OUT AND CALIBRATION3.1 010C Wind Speed Sensor Check-OutA. Spinning the anemometer cup assembly will produce a series of pulses (40pulses per revolution). To verify sensor output, monitor this signal with either thetranslator module, data logger, or an oscilloscope. (Refer to Frequency vs. WindSpeed Table 3-1). Spinning the hub of the wind speed transmitter without thecup assembly mounted and allowing it to coast to a stop will give a goodindication of threshold performance; a jerky or sudden stop indicates damage tobearings, bent drive shaft, or obstruction in the light chopper.B. Inspect the cup assembly for loose cup arms or other damage. The cupassembly cannot change calibration unless a mechanical part has come loose orhas been broken. If a cup arm is loose or broken the calibration of the sensormay be affected.C. If the sensor heater is used, check internal heater operation by sliding sensorcover down and touching the housing behind the printed circuit board. Thehousing should feel warmer than the adjoining metal parts. The sensor has abuilt-in heater that is designed to provide a raise in the internal temperature,providing a small amount of positive pressure. This heater requires as external12 V (@500ma) power supply.FREQUENCY vs WIND SPEED FOR 010 SENSORTABLE 3-1Transfer FunctionsMiles per hour: Meters per second:rpm = 16.767 * (V mph - 0.6) rpm = 37.522 * (V m/s - 0.27) V mph = (rpm / 16.767) + 0.6 V m/s = (rpm / 37.522) + 0.27 f Hz = (V mph - 0.6) / .08946 f Hz = (V m/s - 0.27) / 0.039976 V mph = V m/s * 0.44704 V m/s = V mph / 0.447044.0 MAINTENANCE AND TROUBLESHOOTING4.1 General Maintenance Schedule*6 – 12 Month Intervals:A.

It also includes an internal compass that allows for automatic alignment of wind direction to magnetic north, regardless of the sensor’s orientation.The small footprint and power efficiency of the 30.5 make it ideal for remote regions, urban environments, air quality networks, construction/remediation sites, and other network applications. The sensor works well in permanent (cooperative weather networks, schools, public information dissemination) or temporary (emergency response, audit, research program support) installations.Designed for maximum portability and utility, the 30.5 is well suited for rapid deployment and use by one person under all conditions. The unit may be mounted on a tower, tripod, or vehicle mast. Data outputs are a serial, digital message as well as simple analog voltage outputs that can be interfaced to most data logging systems.2.

Operational CheckoutConnect the 30.5 serial or analog signal wires to a data logger or recording device. Connect power to the sensor cable per wiring diagram in section 3.3. The 30.5 will automatically start measuring wind speed and direction and outputting data on both the serial and analog outputs. Any connected recording electronics should start displaying or recording measurements from the 30.5. Verify the data seems reasonable by comparing it to data from a local weather source. If the data looks OK, the unit is in operation. If data is questionable, contact Met One Instruments, Inc. Service Department for further guidance (see the Technical Support section at the beginning of this manual).3.5. MaintenanceThe unit has no moving parts and therefore requires no periodic maintenance for wear items. It is recommended that the data be checked every 6 -12 months to be sure there has been no failure of any of the electrical components. This can be done by placing a small container (at least 12inch diameter) over the sensor to zero check the wind measurement. The wind readings can be checked against a collocated wind sensor. The 30.5 sensor can also be returned to Met One for wind tunnel verification / calibration. 3.6. Setting Magnetic DeclinationThe internal compass automatically corrects the wind direction in the 30.5 to magnetic North. This means that the unit will not require directional alignment or orientation upon deployment.If it is necessary to measure wind direction referenced to True North it is important to understand and know the magnetic declination of the area in which the sensor is being operated. The declination in the 30.5 is factory set at zero degrees. To change this, refer to the MD command instruction in section 7.1.10 for setting the Magnetic Declination.4. User Selectable OptionsThe following User Defined Options can be set following the instructions detailed in Appendix A.AT Ambient Temperature Printout Toggle On/OffBV Battery Voltage Printout Toggle On/OffCV Compass Reading Printout Toggle On/OffID View / Set Instrument IDMA Set MODBUS AddressMD Set Magnetic DeclinationME Metric or English UnitsOI Set Output IntervalRT Output Record TypeRV Display Firmware Version NumberST Set Serial Trigger AddressSU Set Wind Speed UnitsTU Set Temperature UnitsQ Quit Terminal Mode and Save changes5. User InterfaceThe output of the 30.5 is a fixed length, comma delimited, serial data stream. The serial output is factory set for 9600 baud, no parity, 8 data bits, 1 stop bit, and no flow control. The output interval default is once per second. This may be changed using the OI command (see Appendix A). The data is easily viewed and can be displayed and captured using Met One Instruments’ Comet Software or other terminal communication program.An example of the standard output format is shown below:000.6,272,U0,*02257 CR/LFEach parameter is a fixed length with leading zeros separated by a comma. The string terminates with a Carriage Return and Line Feed. Field parameters are defined as: 000.6,272,+23.1,12.7,090,U0,*02257 CR/LFWS,WD,AT,BV,COMP,CONFIG,CheckSumNote thatThe wind speed and temperature units can be changed with the SU and TU terminal commands, respectively. Please refer to Appendix A for more information. NOTE: Ambient Temperature, Compass reading, and Battery Voltage values are OFF by default in the output string, and can be added using the AT, CV, and BV commands, respectively.; see Section 7.1.2 for details and an output string example.A check sum parameter is added to the end of the message (ex: *02257).The check sum is the addition of all the characters from the start of the message through the first character preceding the asterisk (*). The check sum is expressed as a decimal number. This is a 16-bit sum and should not overflow past 4 digits given the number of characters in the output string.Polled data mode (RS232 or RS485)The sensor can be set for polled data mode instead of continuous serial output by setting the OI command to Zero and using the serial trigger string to request a data string. Refer to the ST terminal command in Appendix A for instructions on setting the Serial Trigger.6. Standard ConfigurationSerial InterfaceThe serial interface is fixed at 9600 Baud and configured for No Parity, 8 Data Bits and 1 Stop Bit, with no flow control.Analog InterfaceThe analog outputs for Wind Speed and Wind Direction are fixed at 0-1VDC.Wind SpeedThe Wind Speed unit choices are m/s or mph. The default is M/S. The Speed range for M/S is 0-60. The Speed range for MPH is 0-134.TemperatureThe Temperature unit choices are Degrees C or Degrees F. The default is Degrees C.

MD –Magnetic DeclinationThe automatic alignment compass in the 30.5 sensor provides Wind Direction automatically adjusted to MAGNETIC north. Software in the Interface allows the setting of a declination angle to correct the Wind Direction output to TRUE north. It is recommended that this procedure be done in the lab but can be done in the field as well. Once the declination angle is set in the sensor, it is stored in non-volatile memory, and does not have to be reset each time the sensor is fielded. The declination angle must be reset only if the system is used in a different geographical location separated by many miles from the location where the declination was originally set.It is suggested that the magnetic declination be determined before performing this calibration. Visit the following web site for help in determining the correct declination for the installation site:/geomag/declination.shtmlClick “Compute your declination”. On the next page, enter either zip code, or select country and city, then click “Get Location” and then “Calculate”. Alternatively, longitude and latitude can be entered, and then click “Calculate”. Declination is reported in Degrees, Minutes and Seconds. Divide minute’s value by 60 to get decimal fraction of degrees (I.E. 50 minutes = 0.8 degrees). If the declination needs to be adjusted, please use the MD command as shown below.Read or Set the Magnetic DeclinationCOMMAND RESULTMD<cr> Report Magnetic Declination settingMDXX.X<cr> Set Declination to XX.X DegreesNote: West declination values are entered and reported as negative values.7.1.11.

Modbus operation:The 30.5 can be queried for data using the Modbus RTU protocol. The 30.5 will automatically detect a Modbus data request via its standard RS-232 or RS-485 interface, and will change to Modbus mode, ready to send out data as requested by a connected Modbus Master.If the 30.5 is to be used as a Modbus device, it is recommended to set the Output Interval (OI) command to 0 (zero) to turn off the 1/second output, as shown in section 7.1.11. This will prevent any serial traffic conflicts.The 30.5 can be assigned a Modbus address between 1 to 247, which allows it to be addressed on a multiple device network. Setting the Modbus address to 0 will disable the Modbus functionality of the 30.5. The 30.5’s current measurement data can be polled via Modbus using the 3X and 4X register addresses: 3X RegistersModBus Name Addr Type PointsMB_123456 = 0 float 2 Known value for easier Byte Order configurationMB_SN = 2 Char 5 Serial Number StringMB_Revision = 7 char 20 39 Char + Zero Terminator word aligned to 40 bytesMB_WS = 100 float 2 Wind SpeedMB_WD = 102 float 2 Wind DirectionMB_AT = 104 float 2 Ambient TemperatureMB_Batt = 114 float 2 Supply VoltageMB_Comp = 116 float 2 Compass Heading4X RegistersModBus Name Addr Type PointsMB_Byte_Order = 0 Int 1 1 thru 49. Appendix B9.1. Theory of OperationWindThe Met One 30.5 sonic anemometer operates on the principal that the speed of the wind affects the time it takes for sound to travel from one point to a second point. 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 is used to measure air movement in two perpendicular axes, which are used to calculate Wind Speed and Wind Direction.Ambient TemperatureThe temperature sensor in the 30.5 measures air temperature for the purpose of calculating the wind measurements only. It is not designed to comply with EPA or WMO ambient temperature measurement guidelines.Automatic Alignment CompassThe internal compass module is low power and compact. It employs a pair of magneto-resistive sensors, which change with varying magnetic field strengths, to sense the Earth’s magnetic field.The 30.5 microprocessor measures the output of the internal compass and then corrects the wind direction data for the orientation of the sensor. The output of the 30.5 wind direction is relative to magnetic North. A user programmable value of Magnetic Declination may optionally be entered through terminal mode. This enables wind direction output relative to True rather than Magnetic North.。
