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.
