General Description
(See
fig.
la)
The Gilibrator is comprised of the following basic components: Flow
Cell Assembly, Control Unit (base), Battery Charger and Soap Solution. Different sized inter-changeable Flow Cell Assemblies are available for use as
follows:
Low Flow
: 1 to 250 cc/min.
S t a n d a r d F l o w : 2 0 cclmin t o 6 L P M
High Flow
: 2 to 30 LPM
In addition to the basic components, an optional Printer Module is
available.
The printer provides a hard copy record of calibration data,
however,
identical data is displayed on the LCD of the Cilibrator Control
Unit during calibration.
1. Flow Cell Assembly (See fig. lb)
The Flow Cell Assembly consists of a Bubble Generator and Sensor
Block. Each Bubble Generator is sized to produce a bubble film stretched
across the diameter of the flow cell tube which is carried by airflow from
the bottom to top of the tube. A s t h e b u b b l e t r a v e r s e s p a s t t w o i n f r a r e d
sensors, each sensor transmits a signal to the Control Unit (base) indicat i n g t h e p a s s a g e o f t h e f i l m . The Flow Cell Assembly incorporates a manual
bubble initiation push button which starts the film on its travel up the
tube.

Primary Airflow Standard
To be a primary standard, all values must be absolute and measured as
absolute.
A primary standard airflow measurement is a volume divided by a
time interval as performed by the Control Unit of the Gilibrator.
The
volume, V, is measured volume of space between two infrared sensors. The
time is that interval needed for a soap film bubble to traverse between the
two sensors which bound the volume. T h e r e f o r e , V/t, t h e v o l u m e p e r u n i t o f
time, becomes the airflow and is prime because all measurements are basic...
volume and time.
In today’s technology, time is measured by an electronic
clock whose accuracy exceeds that of volume measurements by orders of
magnitude, hence, the control accuracy volume resides solely with volume
measurements.
2. Bubble Generation and measurement
a) The Gilibrator consists of two elements, the Flow Cell Assembly and
the Control Unit (base).
T h e f u n c t i o n o f t h e F l o w C e l l A s s e m b l y -is to
generate a clean consistent bubble which traverses up the flow tube. Measurement of the traverse time is done by infrared sensor pairs which are
m o u n t e d a t t h e b o t t o m a n d t h e t o p o f t h e S e n s o r B l o c k . The volume bound by
these sensors is specifically adjusted to a volume standard by allowing the
upper sensor blocks to move in unison so as to enable this calibration to be
set accurately to a primary volume standard,
A second function of the
sensor block provides the interfacing code to define the cell volume as well
as sensitivity adjustments for the optical sensor systems.

sent to the micro processor which in turn does the necessary mathematical
calculations which allow the flow to be displayed directly on the LCD
readout.
In order to insure the highest accuracy possible, a Delete and
Average function are provided on the Control Unit. The Delete allows for
subtracting out an obvious malformed bubble and the average allows the user
to obtain average information without pencil or paper. A printer interface
allows connection of a Printer Module so that hard copy can be produced.

1. Remove the Storage Tubing (25) from the upper Outlet Boss 26)
of the upper cell. Fill the dispenser bottle provided with
Cilibrator soap solution. Using the rubber Storage Tubing as a
funnel, slowly add soap solution from the dispenser.
2. The amount of soap needed is determined by depressing the
Bubble Initiate Button (22) and holding it down in the lower
position. Continue to add enough soap solution until the angled
edge at the bottom of the Bubble Generator Ring (21) is immersed
in the solution. Do Not Overfill! (See fig. 6)
3. After filling is completed, the rubber Storage Tubing (25) may
be removed completely.
Recap the soap dispenser bottle for later
u s e . N O T E : If the Flow Cell Assembly is not going to be used for
a prolonged period of time, reinstall the rubber Storage Tubing
between the inlet and outlet bosses (23 t 26). This will p&vent
evaporation from occurring which may cause the solution’s concentrations to alter.

Theory
of Operation
The Printer Module is powered and interfaced to the Control Unit
pf t h e C i l i b r a t o r b y m e a n s o f a n I n t e r c o n n e c t C a b l e .
During a test
series, the Control Unit transfers the sum of calculations of a given
calibration bubble and provides the flow rate, the sample number and an
average of the successive flow rates determined in that calibration
series.
The buttons on the Control Unit are used in conjunction with the
Printer module during calculation.
Delete, Auto Average and Reset
buttons are provided to subtract false readings and to initiate new
calibration sequences.
Calculations are automatically provided by the Control Unit and
transferred to the printer for a hardcopy readout. This is printed
onto a thermal sensitive roll paper which advances a single line after
printing out each successive reading. These hard copy calculations are
retained for calibration records.

The
Printer will print in sequence the flow, average and sample
number after each successive reading.
NOTE : If you do not need a hard copy printout from the Printer Module, turn
it OFF.
This will preserve the battery life of the Gilibrator as the
printer is powered by same.

used in conjunction with the printer during calibration. They are
as follows:
a) Average - In order to display average and number of samples,
depress and hold average button.
Releasing the button will
display the last reading.
Repressing will display the number of
samples accumulated for that averaging sequence.
Releasing the
button will once again display the last flow reading. Additional
pressing and holding will repeat this sequence.
b. Reset - To reinitiate the sequence for additional pumps,hit
the Reset Button. T h i s w i l l z e r o o u t s a m p l e a n d a v e r a g e r e g i s ters within the Control Unit and will cause the printer to index
one line and reprint headings. This denotes the start of a new
sequence.
The Reset Button may also be used if a malformed bubble
is generated and has not been been subtracted from the average by
use of the Delete Function.
c.Delete
- To delete obvious false readings, press the Delete
Button and subtract the false reading from the average. This
resets the average and sample number back to the previous reading.
5. Storage E Maintenance
