6. INITIAL SETUP
6.1. Verify that the compressed air supply is connected.
6.2. Connect the control & blower units to their required power source.
6.3. Fill the generator to the proper level with the oil specified in the Factory Settings sheet
(see Section 7 - Filling Methods).
NOTE: Over or under filling the generator will result in an unstable aerosol source.
WARNING: If liquids other than specified on the Factory Settings sheet are used, the
generator will not function to specification.
6.4. Depress the power button and start the blower system by raising the breaker contact
located at the left side of the control unit to the ON position
6.5. Follow the Operations Sections 8.1 to 8.4 until the System Start menu is reached. At
this point compressed air is being supplied to the aerosol generator.
6.6. Place the aerosol toggle switch to the ON position to start aerosol production.
6.7. Check the system settings against the Factory Settings sheet referencing the serial
number of the control unit.
6.8. Power the unit off by pressing the red push button.
6.9. Perform the maintenance operation at this time (see Maintenance Manual, Section 10
– Initial Setup).
7. FILLING METHODS
7.1. Proper Fill Level
The generator tank is marked with a fill line at the center point of the reservoir. The oil level
should always be maintained within ± 0.50 inches of the fill line.
WARNING: Do not fill generator more than 0.50 inch above the fill line.
13
WARNING: If the generator is run with the liquid level below the lower limit, the aerosol
concentration will become unstable and give faulty test results.
7.2. Generator Reservoir Fill
Remove the generator assembly from the unit by sliding the generator outward.
Disconnect the hose attached to the regulator/check valve assembly located on the side of
the generator. Release the bail assembly by raising the handle and lowering the lid/bail
assembly. Rotate the lid slightly and remove from the generator body and fill the generator
reservoir with oil to the indicated fill line. Reverse the above procedure to reinstall the lid.
Check that the bail locking mechanism is fully engaged and the lid sealing ‘O’ ring is in place.
To re-install the generator, reverse this procedure making sure that all tubing connections are
fully inserted and secure.

11. Gravimetric Measuring
A gravimetric reading is used to determine the aerosol concentration of the unit. Measuring
the amount of aerosol collected and the total airflow during the sample time performs this as
explained below.
11.1.
MEASURING PROCEDURE
Use a 47 mm extra thick, water resistant glass fiber filter to obtain the sample (equivalent to
Pall Life Sciences 66078)
Weigh and record the mass of the filter media sample in grams.
Place the sample filter into the supplied gravimetric test fixture. Disconnect the upstream
sample line from the rear of the control unit and insert the gravimetric test fixture in series
with the upstream sample line using its attached disconnect fittings.
Follow the Gravimetric Setup menus in Section 10.5.
Remove the test filter and record the mass in grams.
Determine the amount of aerosol collected by subtracting the weight before sampling from
the weight after sampling.
Determine the concentration in µg/L by dividing the weight of aerosol collected by the total
flow in liters.
Example

FMA-900 Series Air Velocity Transducers
General Description
The OMEGA® FMA-900 air velocity mass flow transducer is ideal for economical
monitoring of clean air flows in ducts and pipes, while producing very little
permanent pressure drop in the flowstream. The FMA-900 employs two rugged
glass-coated RTD elements, protected by a 1/4” diameter 304SS tube with a
“window” cut out. One RTD is the velocity sensor, while the other RTD provides
ambient air temperature compensation. The velocity sensor is heated to maintain
a constant (approximately 30° C) temperature differential above the ambient air
temperature, as measured by the second RTD element. The cooling effect of the
air flow experienced by the velocity sensor is measured and converted to an
electrical output signal proportional to air velocity. The FMA-900 is provided
with a 13” long probe as standard. The 304SS tubing is provided with inch
marks for ease of insertion depth.

Important Considerations Before Installation
CAUTION
The FMA-900 air velocity transducer is not explosion-proof, nor is it
intrinsically safe. Do not use for flammable or hazardous
gases, or in hazardous areas.
!
The FMA-900 air velocity transducer is intended for use with clean air or
nitrogen ONLY. Do not use with other gases, as other gases will produce an
uncalibrated, non-linear output signal. In addition, air carrying dust or oil (such
as found in blower/compressor systems that utilize oil) can lead to coating of the
sensor and thus, inaccurate readings. Refer to the Maintenance section for more
information on cleaning the sensor.
The FMA-900 is a bi-directional device; flow in the forward or reverse direction
provides the same output.
Installing the Flowmeter
The FMA-900 air velocity transducer can be mounted vertically or horizontally
without shift in calibration.
1.
Remove the plastic protective cap from the sensor tip.
2.
Run a length of straight pipe before and after the flowmeter. The amount of
upstream straight pipe run required depends upon the type of obstruction which
is immediately upstream of the flow sensor. See Table 2-1 for specific
requirements. Downstream of the flow sensor, in all situations, run 5 diameters
of straight pipe, regardless of the downstream obstruction.
3.
Align the FMA-900 with the air flow. Make sure the width of the electronics
box (2 inches) is parallel with the flow stream.
The score line on the tubing is another way of aligning the air flow sensor with
the flow stream. The score line starts from the center of the transducer window
and as a result it can be aligned properly.
One means of installing the probe into a flow stream is to utilize a compression
fitting, such as OMEGA’s SSLK-14-14 stainless steel compression fitting with
Teflon ferrules, which permits adjustment of the insertion depth of the probe.
On Remote Probe Models (-R), connect the remote probe cable to the Electronic
Housing.

Measuring Air Flow
The FMA-900 measures standard velocity, which is the mass velocity of the air
referenced to 25° C and 760 mm Hg. No temperature or pressure corrections are
required. Where SCFM (standard cubic feet per minute) measurements are
desired:
1.
Locate the point of average velocity in the pipe or duct.
2.
In round pipes, under turbulent flow conditions (where the Reynolds number is
greater than 5,000), mount the velocity sensor approximately 1/8 of a pipe
diameter in from the the pipe wall. For example, in an 8” diameter pipe, mount
the probe 1” in from the pipe wall.
3.
For pipes or ducts where the flow is not turbulent, or the flow profile is not
symmetrical (due to inadequate straight pipe runs, etc.), perform a traverse of
the duct, in accordance with standard duct traversal methods as recommended
by ASHRAE or the National Air Balance Council.
4.
To obtain SCFM, once the probe is mounted in the location of average velocity,
multiply the average velocity readings (in SFPM, standard feet per minute) by
the cross-sectional area of the pipe or duct, in square feet. For standard pipe,
these values can be found in the technical section of the OMEGA Complete Flow
and Level Measurement Handbook and Encyclopedia®.
Maintenance
Except for intermittent removal of the sensor from the line for cleaning, there is
no routine maintenance for the FMA-900. If the probe becomes coated with dust,
blow the dust away with clean air. If the probe is coated with sticky material,
clean it with a solvent which is compatible with epoxy, glass, and 304SS, and
which will not leave a residue on the sensor. You may clean the sensor with
water or alcohol (Ethanol) and an artist’s brush.
Calibration
Each FMA-900 is individually calibrated in a NIST-traceable wind tunnel. For
calibration certification or calibrating to a new range, the unit must be returned
to OMEGA. To obtain an Authorized Return (AR) number, call the OMEGA
Customer Service Department with a Purchase Order number to cover the
recalibration charges.
