推荐几个调试方法:
首先要确保设备接线正确,且严格合乎规范。
终端电阻法: 在最后一台485设备的485+和485-上并接420欧姆的终端电阻来改善通讯质量.注意：许多485布线文档推荐使用120终端匹配电阻、但是使用120欧电阻值太小，会导致功耗过大，且会拉低485+和485-之间的压差，影响信号的传输，因此我们推荐使用较大的几百欧的终端匹配电阻。

Some mobiles are automatically calibrated in the first installation phase (Samsung GT-I9000, GT-9300, GT-S5570). If necessary it is possible to change the calibration parameters in the settings page. For a perfect calibration you need a professional anemometer, but you can get a fair calibration with the following:1.Noise level: in the settings page set thenoise level to 0; start the dynamicfunction (in m/s) in a silent room (noexternal noises like in a library or abedroom), read after 10 seconds theaverage value (fix) : if >0, set the noiselevel to the fix rounding up to the nearestinteger (in the settings page) .2.Specify the Maximum SPL of yourmobile : it is possible to specify themicrophone maximum SPL in dB in thesettings page (default 90, suitable formost mobiles)Troubleshooting1.Wrong SPL maximum value: all yourmeasurement are higher or lower thanexpected. Enter in the settings menu andselect the correct SPL maximum value2.Attenuation on mobile microphone:your measurements never reach themaximum possible wind speed (thethreshold blue line, see next item) evenwith a high wind (or just with a strongblow on the mic): restart android3.No signals detected below 1 m/s or over20 m/s: The smart phone microphonesdo not work under/over a specificpressure. In the threshold menu you candisplay the blue line of the maximumwind speed (Mic Maximum) that can bedetected by your microphone with thecurrent calibration. For instance asmartphone with a microphone with amaximum SPL of 90db without anyspecial windshields cannot measure windspeeds greater than 16 m/s: thebackground noise level on your signalcan introduce a further reduction.。
风速计使用说明
风速计使用说明风速计是测量空气流速的仪器。
它的种类较多，气象台站最常用的为风杯风速计，它由3个互成120°固定在支架上的抛物锥空杯组成感应部分，空杯的凹面都顺向一个方向。
整个感应部分安装在一根垂直旋转轴上，在风力的作用下，风杯绕轴以正比于风速的转速旋转。
另一种旋转式风速计为旋桨式风速计，由一个三叶或四叶螺旋桨组成感应部分，将其安装在一个风向标的前端，使它随时对准风的来向。
桨叶绕水平轴以正比于风速的转速旋转。
原理风速计其基本原理是将一根细的金属丝放在流体中，通电流加热金属丝，使其温度高于流体的温度，因此将金属丝风速计称为“热线”。
当流体沿垂直方向流过金属丝时，将带走金属丝的一部分热量，使金属丝温度下降。
根据强迫对流热交换理论，可导出热线散失的热量Q与流体的速度v之间存在关系式。
标准的热线探头由两根支架张紧一根短而细的金属丝组成，如图2.1所示。
金属丝通常用铂、铑、钨等熔点高、延展性好的金属制成。
常用的丝直径为5μm，长为2 mm；最小的探头直径仅1μm，长为0.2 mm。
根据不同的用途，热线探头还做成双丝、三丝、斜丝及V形、X形等。
为了增加强度，有时用金属膜代替金属丝，通常在一热绝缘的基体上喷镀一层薄金属膜，称为热膜探头。
热线探头在使用前必须进行校准。
静态校准是在专门的标准风洞里进行的，测量流速与输出电压之间的关系并画成标准曲线；动态校准是在已知的脉动流场中进行的，或在风速仪加热电路中加上一脉动电信号，校验热线风速仪的频率响应，若频率响应不佳可用相应的补偿线路加以改善。
0至100m/s的流速测量范围可以分为三个区段：低速：0至5m/s；中速：5至40m/s；高速：40至100m/s。
风速仪的热敏式探头用于0至5m/s的精确测量；风速仪的转轮式探头测量5至40m/s的流速效果最理想；而利用皮托管则可在高速范围内得到最佳结果。
正确选择风速仪的流速探头的一个附加标准是温度，通常风速仪的热敏式传感器的使用温度约达+-70C。

Correction FactorsFor Hot Wire Anemometers:If the environmental conditions are other than thestandard conditions (70°F and 29.92 inches of Hg), you need to correct for them. Here is the correction factor equation:K1 = (29.92 / P) x (460 + T) / 530 where…P is the Barometric pressure in inches of Hg T is the ambient temperature in DegreeThere is a second correction factor which is a function of the air probe geometry (K2).The following table lists K2 for different air probes. So, the actual air velocity is as follows:Actual Value = Measure Value (average value over one minute time) x K1 x K2For Vane Type Anemometers:You only need to correct for the air probe geometry (K2).

The higher the flow rate, the more chance of creating currents. • Air Probe geometry affects the readings. There is a correction factor table for different types of air probes (Hot wire & Vane type).• T he air flow rate of the wind tunnel depends on the air temperature and barometric pressure. Adjust it accordingly.• T his instrument should only be used for its intended purpose in accordance to the instruction manual.Operating the Wind TunnelBefore operating the wind tunnel, please follow all the precautions stated in the previous section and then proceed as follows:1. C onnect the cable from the DC Fan to the back of the Control unit box labeled ‘Fan Control’. Make sure the power switch in the back of the control unit is off.2. C onnect the AC input of the Control unit to a line voltage (90 to 250 VAC @ 50/60 Hz) with the Power cord provided.3. S et the air speed selector switch on the front of the control unit to Zero position (Meaning Zero airvelocity). Turn on the Power switch in the back. You will see the power LED indicator on the front of the control box turns on.The air speed selector switch can be set to four fixed air speeds. The wind tunnel has been calibrated at these four air speeds. The standard conditions are at 70°F (21.2°C) ambient temperature and 29.92 inches of Hg of Barometric pressure. There are four plugs in front of the control unit box. Removing the plugs, you will have access to potentiometers that will allow you to adjust the air speed at the four settings.For Hot Wire Anemometers:1. U se the Chamber Door (Solid) to cover the test chamber.2. I nsert the air probe into Port #1. Port #2 is used to insert a reference air probe if desired. Refer to Front View of WTM1000 for location of ports.3. A lign the air probe sensor to the center of the chamber using the scribed line on the outside of the chamber.4. U se the Teflon Ferrules and “hand-tighten” the probein place. Do not use tools or wrenches.WGS/START HERE ARROWGS/START HERE ARRO 2WGS/START HERE ARRO34Using This Quick Start ManualUse this Quick Start Manual with your WTM-1000 Laboratory Grade, Bench Top Mini Wind Tunnel for quick installation and basic operation.

The Wind Tunnel has an electronic control unit where it controls the DC Fan speed and provides four selectable fixed air speeds. The fixed air speeds are:• 2.5 m/s (492 FPM)• 5 m/s (984 FPM)• 10 m/s (1969 FPM)• 15 m/s (2953 FPM)In addition, there is a REMOTE selection on the electronic control unit selector switch. This will allow connecting an external potentiometer to control the DC fan speed and be able to vary the speed from 0 to 15 m/s. A cable to connect an external potentiometer to the control unit isSetting Up the Mini Wind TunnelPrecautions:A wind tunnel’s performance can be severelydiminished if not used properly. Please follow the following tips:• D o not use the wind tunnel in small rooms. The air flow creates currents that undermine the wind tunnel’s accuracy.• A void locating the intake and exhaust toward open windows, doorways or corridors where people are walking. The effect of air current changes across the intake has a severe effect on the flow rate changing in the wind tunnel.• T here should be at least 1.5 m (5 feet) clear space in front of and behind the wind tunnel. No obstacles, moving objects, open doors or windows.For Vane Type Anemometers: 1. R emove the chamber door. Open the clamp in the adjustable mounting block by turning the wheel.2. P lace the vane propeller inside the chamber. Make sure it is in the center of the chamber.3. Place the vane window door.4. S ecure the vane propeller in place by tightening the clamp using the wheel.5. S lide the Vane Clamp sleeve over the vane window door and up against the vane probe to minimize any air leaks.Once the air probe is in place (either Hot Wire or Vane Type), turn the air speed selector switch from 2.5 m/s (492 FPM) up to 15 m/s (2953 FPM). Check the air probe reading vs. the switch setting on the wind tunnel.Front Panel, Control Unit BoxRear Panel, Control Unit BoxImportant Components of Mini Wind Tunnel andOverall Dimensions。

Series AVUL Air Velocity Transmitter 计量手册说明书
The Series AVUL Air Velocity Transmitter quickly and accurately measures air velocity or volumetric flow in imperial or metric units. Simultaneous current and voltage outputs on all models provide universal inputs to monitoring equipment while the output range, units, and 0 to 5/10 VDC output can be configured via local DIP switches. The optional integral display, or the portable remote display tool, provide a convenient way to locally monitor process values and configure the unit.Models are available in 3% and 5% accuracy models to suit a variety of needs, and the optional BACnet MS/TP or Modbus ® RTU/ASCII communication protocol allows units to be daisy-chained while providing access to all of the velocity and flow data, as well as additional information such as air temperature.INSTALLATIONDuct Mount:The transmitter should be mounted away from fans, corners, heating and cooling coils, and other equipment that will effect the measurement of the air velocity. It is recommended that the AVUL is mounted 10 duct diameters downstream of any disturbances and 5 duct diameters upstream of any disturbances, if possible.1. Mark and drill a 0.750-0.938˝ (20-24 mm) diameter hole into the duct.2. Insert and center the duct mount flange in the previously drilled hole and marklocation of the three mounting screw holes.3. Remove the mounting flange and drill or punch the mounting holes in the marked locations.4. Fasten the flange to the duct using three #8 x 1/2 pan head sheet metal screws. Do not over tighten screws.5. Insert the AVUL probe into the ducts mount flange and set the desired insertiondepth.6. Note the flow direction and unit alignment as shown on sensor tip and product label, tighten probe retention set screw on the duct mount flange screw to affix the probe in place.Electrical Connection:The Series AVUL is powered and simultaneously transmits a two-wire 4 to 20 mA current output and a three-wire 0 to 5 VDC or 0 to 10 VDC voltage output via a removable four conductor terminal block. The transmitter power supply common is used to reference the current and voltage outputs so either current, voltage, or current and voltage may be wired according to the application. The range of the voltage output can be selected using the on board DIP switches as described in the Analog DIP Switch Settings section of this manual.Power SupplyChoose a power supply with a voltage and current rating sufficient to meet the power specifications under all operating conditions. If the power supply is unregulated, make sure the output voltage remains within the required voltage range under all power line conditions. Ripple on the supply should not exceed 100 mV.The terminal block is removable, and each of the terminals are labeled underneaththe terminal block on the circuit board. As the power supply and outputs share thesame common signal (GND), the outputs may have separate wires but must effectivelyjoin at terminal 2 of the transmitter, asshown in Figure 1. The connections to thetransmitter are made to terminals 1, 2, and 3 (PWR, GND, and IOUT respectively) onthe terminal block as shown in Figure 4.Figure 1Current Output WiringAlthough low loop resistances are recommended, the absolute maximum current loopload resistance, R MAX , is defined by the following the equation:R MAX = (V PS – 2.0) / 0.02 where V PS is the power supply voltageFor a 24 VDC nominal power supply, this evaluates to R MAX = 1100 ohms.Shielded two wire cable is recommended for current output loop wiring. Ground theshield at the power supply end only.The maximum length of connecting wire between the current transmitter and thereceiver is a function of wire size and receiver resistance. That portion of the totalcurrent loop resistance represented by the resistance of the connecting wiresthemselves should not exceed 10% of the receiver resistance. For extremely longruns (over 1,000 ft.), it is desirable to select receivers with higher resistances in orderto keep the size and cost of the connecting leads as low as possible. In installationswhere the connecting run is no more than 100 ft, connecting lead wire as small as No.22 Ga. can be used.Voltage Output OperationThe terminal block is removable, and each of the terminals are labeled underneath theterminal block on the circuit board. The voltage output and the power supply must haveseparate wire leads that are only joined at terminal 2 of the transmitter, as shown inFigure 2. Additional error may occur for the voltage output if a single wire is used or ifthe wires are joined at the power supply or receiver. The connections to the transmitterare made to terminals 1, 2, and 4 (PWR, GND, and VOUT respectively) on the terminalblock as shown in Figure 4.The minimum receiver load is 1 kΩ. The resistance due to the wire should be lowcompared to the receiver load resistance. While the voltage at the terminal blockremains unchanged with a 10 mA current flow, resistive losses in the wiring do causeerrors in the voltage delivered to the receiver. For a 1% accurate gauge, the resistanceof the wires should be less than 0.1% of the value of the receiver load resistance. Thiswill keep the error caused by the current flow below 0.1%.The output across VOUT and COM will be either 0 to 5 VDC, 0 to 10 VDC, or theinverse depending on the DIP switch setting. See the Analog DIP Switch Settingssection for more information.Figure 2Voltage Output WiringDO NOT EXCEED SPECIFIED SUPPLY VOLTAGE RATINGS.PERMANENT DAMAGE NOT COVERED BY WARRANTY WILLRESULT.DO NOT EXCEED SPECIFIED SUPPLY VOLTAGE RATINGS.PERMANENT DAMAGE NOT COVERED BY WARRANTY WILLRESULT.DO NOT EXCEED SPECIFIED SUPPLY VOLTAGE RATINGS.PERMANENT DAMAGE NOT COVERED BY WARRANTY WILLRESULT.Simultaneous Current and Voltage Output OperationThe terminal block is removable, and each of the terminals are labeled underneath the terminal block on the circuit board. The voltage output and the power supply must have separate wire leads that are only joined at terminal 2 of the transmitter, as shown in Figure 3. Additional error may occur for the voltage output if a single wire is used or if the wires are joined at the power supply or receiver. The connections to the transmitter are made to terminals 1, 2, 3 and 4 (PWR, GND, IOUT, and VOUT respectively) on the terminal block as shown in Figure 4, which reflects both the 4-20 mA and 0-5/10 VDC outputs in the same circuit. Details of each output are detailed in their electrical connection sections.ANALOG DIP SWITCH SETTINGSThe analog output DIP switches (SW1) are located above the terminal blocks on the left are as shown in Figure 4. A small screw driver or pen can be used to change the position of the switches as required. DIP switch positions for SW2 and SW3 are RESERVED or have no affect.Factory Default Settings (DIP SW1 – All Switches ON)Range = Highest Range Setting (4000 FPM)Units = Imperial (FPM)Voltage Output Range = 0 to 10 VDC Direct / Reverse Output Action = DirectSetting the Air Velocity RangeThe range of the instrument is selected by using DIP switches 1 and 2 on SW1. Table 1 shows the maximum full scale value for the selected range and unit. Refer to Setting the Engineering Units section for information on setting the unit.Setting the Engineering UnitsThe Series AVUL can be configured to indicate velocity in imperial (FPM, CFM) or metric (m/s, m 3/h) units using DIP switches 4 and 5 on SW1, and Table 2 shows the values. The units will be displayed on the optional LCD display if connected.The default operating mode is velocity, but changes can be made, such as flow mode, via the menu system while an optional display or remote display accessory is connected. Please refer to Appendix III for a full menu flow chart.Setting the Output Voltage RangeVoltage Output can be either 0 to 5 VDC or 0 to 10 VDC depending on the position of DIP Switch 6 ON SW1.• When the switch is in the ON position, the output will be 0 to 10 VDC.• When the switch is in the OFF position, the output will be 0 to 5 VDC.Setting the Input / Output ActionThe output will either follow the process directly (DIRECT) or inverted (REVERSED) based on the position of DIP Switch 7 on SW1.• When the switch is in the ON position, the output directly follows the input (i.e. output increases as the input increases).• When the switch is in the OFF position, the output acts in reverse of the input (i.e. output decreases as the input increases).Table 1: DIP Switch SW1 Settings for Full Scale RangeTable 2: DIP Switch SW1 Settings for UnitsFigure 4Analog Dip SwitchesFigure 3Simultaneous Current and Voltage Output WiringDIR10V UNITS RANGEKEYDO NOT EXCEED SPECIFIED SUPPLY VOLTAGE RATINGS.PERMANENT DAMAGE NOT COVERED BY WARRANTY WILLRESULT.All power should be turned off to the transmitter before adjusting the DIP switch settings to avoid electrical shock.Zero CalibrationThe zero calibration can be set by covering the sensor to ensure no air flow andpressing the zero button for 3 seconds. If either the remote or local LCD is present, thedisplay will read ZEro and then sequence back to the home display.SPAN CalibrationThe span calibration can be adjusted only after setting the zero adjustment. It mustbe completed within 5 minutes of the last zero calibration. The span calibration buttonwill be ignored until the zero calibration is completed. Place the sensor in airflow thatmatches the maximum selected range of the transmitter. Press and hold the spanbutton for 3 seconds. If either the remote or local LCD is present, the display will readSPAn and then sequence back to the home display. If the span calibration is attemptedbefore adjusting the zero calibration, the FAiL error message will be displayed brieflybefore returning to the home display.LCD DisplayThe Series AVUL can be ordered with an optional, integral LCD. It comes with ahousing cover and overlay to protect the display. The display will plug into the pins asshown in Figure 5. If the display is not needed for normal operation, the transmitter canbe ordered without the LCD.Another option for models that do not have a display would be to use a Model A-435-Aremote display tool which can plug into the connector shown in Figure 6. The remotedisplay tool has two buttons that function identically to the buttons on the PCB.Display Error MessagesovEr= The air velocity is greater than the maximum span value causing an OverRange ErrorUndEr = The air velocity is less than the minimum span value causing an Under RangeErrorFAiL = When the span or zero buttons are pressed, the air velocity value is out of therange to allow a correct setting. This may be due to a sensor failure.Err1 = The sensor is damaged.PROGRAMMING MENUSHome MenuDuring normal operation, the display will be in the Home Menu and will display thecurrent measured pressure and the engineering units.Menu Access SecurityWhile in the Home Menu, press and hold the Zero and Span buttons simultaneouslyuntil SECUr appears on the display in order to access the other programming menus.Upon releasing the buttons, the display will indicate the current security level.If the current security level is the security level desired (i.e. Security Level 0), pressand hold the span button for 3 seconds to enter the Velocity or Air Flow Menu.If the security level is not the desired level, the security level can be changedtemporarily to a lower security level or permanently to a higher level of security bypressing the zero button. A security code will appear on the display, and it can bechanged to one of the codes listed in Table 3. The span button chooses which digitand the zero button increments the value of that digit. Pressing and holding the spanbutton will store the value.The level of access to the programming menus and the calibration is limited based onthe security level. Table 3 details the level of access for each security level.Figure 5Pluggable Display DiagramFigure 6Remote Display DiagramThere is a 5 second delay from the time the zero or span calibrationbuttons are released until the time that the change in calibrationtakes place. This delay is used to reduce vibration or disturbances of the user relatedto the button presses.The security level that is set in the Programming Menu sectionof the manual will determine which calibrations, if any, may beadjusted by the user.Mode Selection / Digital Dampening MenuFrom the home display, pressing the span and zero button simultaneously for 3 seconds will access the Menu Security Level. If the level is set to 0 or 1, pressing and holding the span button for 3 seconds, a second time, will access the Mode Selection Menu. The display will default to air velocity when first powered up. Pressing the zero button will cycle to air flow.Once the desired mode is displayed, pressing and holding the span button for 3 seconds will save the selected mode and display the digital dampening or averaging parameter. This parameter stabilizes the output and the display by averaging the readings. There are 2.5 readings taken each second and the user can select the number of seconds that they would like to average, up to 240 seconds. The display and the output will continue to update at a rate of 2.5 updates per second, but the moving average is used for these updates.Velocity ModeK-Factor AdjustmentIf the Velocity Mode was selected, pressing and holding the span after adjusting the digital dampening will enter the Velocity Mode and the transmitter will display the engineering unit that has been selected by the DIP switch. Pressing and holding the span button for 3 seconds will enter the K – Factor adjustment. The K – Factor can be adjusted between 0.001 to 9.999. The K-Factor can be adjusted by pressing the span button to select the digit and pressing the zero button to increment the value of the digit. Pressing and holding the span button for 3 seconds will enter the Maximum Output Adjustment parameter.Flow ModeK-Factor AdjustmentIf the Flow Mode was selected, pressing and holding the span after adjusting the digital dampening will enter the Flow Mode and the transmitter will display the engineering unit that has been selected by the DIP switch. Pressing and holding the span button for 3 seconds will enter the K–Factor adjustment. The K–Factor can be adjusted between 0.001 to 9.999. The K-Factor can be adjusted by pressing the span button to select the digit and pressing the zero button to increment the value of the digit. Pressing and holding the span button for 3 seconds will enter the Area Adjustment parameter.Area AdjustmentFor flow applications, the area is multiplied by the velocity to determine the volumetric air flow. The area will be listed in either CFM or m 3/h depending on the DIP switch settings. The units will appear on the display at the time of adjustment. The area can be adjusted by pressing the span button to select the digit and pressing the zero button to increment the value of the digit. Pressing and holding the span button for 3 seconds will enter the Maximum Output Adjustment parameter.Maximum Output AdjustmentThe maximum output can be equivalent to air velocity or air flow. After adjusting the K-Factor, the display will indicate if the adjustment is set for velocity or air flow. Pressing the zero button will toggle between the selections. Pressing and holding the span button for 3 seconds will enter the maximum output adjustment. The maximum output can be adjusted by pressing the span button to select the digit and pressing the zero button to increment the value of the digit. Pressing and holding the span button for 3 seconds will save this value and go to the Security Update Menu.Security Update / Save Changes MenuThe Security Update Menu allows the security level to be set either higher or lower than the current security level setting. This security level will be displayed the next time the Menus are accessed from the home screen. Pressing the zero button cycles through the security levels. Pressing and holding the span button for 3 seconds accepts the new security level and gives the option to save all the menu changes. Pressing the zero button will toggle between yes and no. Yes will save the changes made to all menu items and no will discard all the changes made to all menu items. If the display is set to yes, pressing and holding the span will save the menu items and return the display to the home position.FACTORY DEFAULT PROCEDUREIn order to reset all of the menu settings back to their factory programmed values, press and hold both the span and zero buttons simultaneously for 10 seconds until FACt is displayed on the LCD. Upon releasing the buttons, the unit will be factory defaulted. Since resetting the transmitter will wipe out all changes, it is necessary to zero (and possibly span) the transmitter before taking measurements.MAINTENANCE/REPAIRUpon final installation of the Series AVUL Air Velocity Transmitter, no routine maintenance is required besides zeroing the transmitter occasionally. Besides routine calibration and installation of the LCD, the Series AVUL is not field serviceable, and it is not possible to repair the unit. Field repair should not be attempted and may void warranty.WARRANTY/RETURNRefer to “Terms and Conditions of Sales” in our catalog and on our website. Contact customer service to receive a Return Goods Authorization number before shipping the product back for repair. Be sure to include a brief description of the problem plus any additional application notes.APPENDIX I: Air Velocity / Air Flow Calculations Velocity in m/s is then calculated from the equation:Velocity (m/s) = Velocity (FPM) x 0.00508Flow in m 3/h is then calculated using the below equation:Flow (CFM) = Area (ft 2) x K-Factor x Velocity (FPM)Flow (m 3/h) = Flow (CFM) x 1.6992Table 3: Security SettingsTable 4: Maximum Flow ValuesThis symbol indicates waste electrical products should not be disposed of with household waste.
