INTRODUCTION

Omega’s Model HHF142 digital anemometer is a versatile instrument for measuring air velocity in various applications such as HVAC, aerospace development, industrial process airflow, and fluids research.

Air Volume flow is automatically calculated in units of either cubic feet per

minute (ft

/min) or cubic meters per hour (m3/hr).

The rugged yet precise probes can be used for airstreams that have a wide range of humidity, temperature, and contaminants without compromising accuracy.

Features include choice of probe diameters, custom cable lengths, service temperatures up to 212˚F (100˚C) at the probe, high reliability, and long life.

This manual has been prepared for both HHF141A (1.00” probe) and HHF141B (2.75” probe) models including all optional outputs.

DANGER

Never touch the vane assembly blades and/or thermal sensors. The vane assembly blades may contain sharp edges which may cause minor cuts. The assembly contains precision bearings which are sensitive, and the blades are finely adjusted to specific pitches. Touching this assembly or its parts may cause damage which can affect its operation and the calibration. NOTE: If the vane assembly head or probe head requires cleaning, we recommend a fine mist of isopropyl alcohol and a fine long-haired brush or send the unit in or servicing.

Do not disassemble or heat the batteries or put them into a fire. They may cause burns and the batteries may burst. Please dispose of used batteries in the proper manner per local ordinances.

CAUTION

When measuring, ensure that the direction arrow is facing the direction of airflow.

The arrow indicates the direction of airflow for the data provided on the calibration certificate. It is meant to allow for uniform and consistent readings as per the provided data. The probe will operate in the opposite direction, but the data may be different.

Do not use or leave the instrument in a high temperature, high humidity,

high speed airflows or dusty environments for prolonged periods.

The instrument may not function properly out of the specified operating conditions and/or have a greatly reduced operating life span.

Do not subject the instrument or the probe to strong impacts. Dropping the instrument or the probe may cause damage or malfunction to the instrument and may change the calibration data. We recommend sending it in immediately to be checked.

SECTION 3 – OPERATIONAL NOTES

Caution: Do not attempt to measure flow from a duct that is smaller than the

diameter of the probe head that you are using. This will cause a false reading. Follow the minimum duct cross-section guidelines as detailed below:

2.75-inch Air Probe: Minimum duct width of 2.7 inches (69 cm) Minimum duct height of 2.7 inches (69 cm) Minimum duct diameter of 2.7 inches (69 cm)

1 Inch Air Probe: Minimum duct width of 1.0 inches (2.7 cm) Minimum duct height of 1.0 inches (2.7 cm) Minimum duct diameter of 1.0 inches (2.7 cm)

9009 - Out of Range Error: There are a few circumstances which will cause

the instrument to display

1. Duct dimension is too small: If one of the user-entered duct

dimensions is smaller than the probe diameter as described above, the

instrument will display the out-of-range error.

2. Duct cross-sectional area is too large: If the cross-sectional area of

the duct is too large, the instrument will not be able to display a

meaningful result. The out-of-range error will be displayed. The

maximum duct cross-sectional areas are as follows:

a. 35 ft

b. 20 ft

3. Volume flow rate is too high: If the calculated volumetric flow rate is

higher than 9999 cubic feet per minute (CFM) or 9999 cubic meters per

hour (CMH) the result cannot be displayed by the instrument. The out-

of-range error is displayed.

APPENDIX C – AIRFLOW VOLUME CALCULATIONS

To calculate cubic feet per minute (CFM) from a measured air velocity (FPM), you need the calculated cross-sectional area of the air flow stream:

Volume Flow (CFM) = Velocity (FPM) X Area (sq ft).

In a rectangular duct this cross-sectional area equals the Width times the Height.

W x H=A (cross-sectional area)

In a circular duct this cross-section area equals the radius squared times π (3.14).

R x R x 3.14=A (cross-sectional area)

To convert an area calculated in square inches to an area calculated in square feet (which is required for the Volume Flow equation above) divide by 144: (area in sq in.)/144 = (area in sq ft.).

Example: The air duct is rectangular; the width is 24 in., and the height

is 12 in. The air velocity reading through the duct is 450 FPM. Calculate the Volume Flow.

Step 1: Cross-sectional area = 24 in. x 12 in. = 288 sq in. Step 2: 288 sq in /144 = 2 sq ft. Step 3: Volume flow = Air Velocity x Area, therefore, Volume flow rate = 450 FPM x 2 sq ft. = 900 CFM.

APPENDIX D – ANALOG OUTPUTS (IF EQUIPPED)

If the instrument is equipped with the analog output option, there will be a fivepin connector on the bottom of the instrument. Also, an analog output cable will be included with the instrument. This cable will have a five-pin connector on one end and four tinned wires on the other end.

The instrument will output a Voltage between 0 and 5 Volts that corresponds to the Air Velocity measured by the instrument. The output range, pin assignments, and wire colors are given in the table below. Also shown is a block diagram of the analog output circuit.

*To convert from Volts to Air Velocity in Feet per Minute, multiply by 2000.

► For example, an analog output of 2.375 Volts means that the instrument is

measuring an air velocity of 4750 feet per minute (FPM).

► 2.375 Volts

Note: When using analog outputs, there is an additional ±1% error in the analog output voltage. This is in addition to the normal measurement error. ► For example, an air velocity reading of 500 FPM would normally have an

accuracy of ±1% of reading ±1 digit (±6 FPM) when the data is viewed on the LCD display.

► With the additional error associated with the analog output voltage, the

effective accuracy of the analog output for this air velocity measurement will be ±2% of reading ±1 digit (±11 FPM).

Custom Analog Voltage Outputs are also available – contact Omega for details.

APPENDIX G – VIEWING AND CAPTURING DATA

(IF EQUIPPED WITH EITHER USB OR RS232 OUTPUTS)

NOTE: HyperTerminal is no longer included with Windows Vista or later packages. Previous manuals referenced this program. We now reference, Parallax Serial Terminal.

There are many terminal emulator programs available on the market. It is up to the end-user to determine which program is compatible with his/her system, what settings it may require, and the Omega Engineering product being used. Omega Engineering does not endorse or recommend any of these programs and assumes no liability for their use.

There are many ways to capture the serial port data from the instrument. The simplest method is to use a terminal emulator program.

Using a terminal emulator allows the serial COM port to be opened, with the below port settings, and real-time data to be viewed from the instrument. One such terminal emulator program is Parallax Serial Terminal, available from

www.parallax.com

Open the Parallax Serial Terminal, based on how you installed the program onto your computer. The below screen will come up.

Attach your instrument & probe to your computer via the USB cable. Select the appropriate ‘Com Port:’. In the below example, COM5 is being used. Set the ‘Baud Rate:’ to 9600

Exporting and Graphing Data

Exporting serial port instrument data from the Pacer Instrument to a spreadsheet application such as Microsoft Excel or OpenOffice Calc allows the data to graphed or recorded.

The simplest way to export the instrument data is to use a terminal emulator program, like Parallax Serial Terminal, and either capture the serial data/text to a file (menu selection) or to manually highlight, copy, and then paste the instrument data into an editor such as Windows Notepad.

Once you have the instrument data in a file, save the file as a .CSV type (e.g., InstrumentData.csv).

Open the file in a spreadsheet application such as Microsoft Excel or OpenOffice Calc. A graph of the data as shown below can now be generated.
