SECTION ONE
INTRODUCTION
1.1 OVERVIEW
The Gilian Gilibrator 2 Calibration System is an easy to
use Primary Standard for the calibration of air sampling
equipment. The system includes a high accuracy, elec-
tronic flowmeter that provides instantaneous air flow
readings and cumulative averaging of multiple samples.
Three Wet Cell Assemblies and one Piston Cell Assem-
bly provide a wide range of flow rates and are easily in-
terchangeable using twist-on/off mounting.
A crystal controlled microprocessor Control Unit is de-
signed for accurate data readings. A dual function
DELETE/RESET button on the Control Unit subtracts er-
roneous readings to ensure accurate data, or can can-
cel the current readings completely.
A printer interface on the Control Unit allows you to
output the sampling results to a printer or PC com-
puter. Windows™ compatible Gilibrator 2 Flow Moni-
toring Software is available that allows you to collect,
store, and plot flow samples.
Features of the Gilibrator 2 Calibration System include
an easy-to-read display; simultaneous display of flow
rate, flow average, and number of samples taken; dis-
play indicators for LOW BAT, WAIT, ERROR 1, and
ERROR 2; and automatic power shutoff when the unit
is inactive for 15 minutes. You can also specify the
number of samples to be taken (5 to 95) in 5 sample
increments.
Gilibrator 2 Calibration System Kits include either a
Wet or Piston Cell Assembly, Control Unit Base (either
CE or non-CE approved), Battery Charger, Tubing, and
Soap Solution & Dispenser (Wet Cells only). A 15-to-9
pin adapter is included with the non-CE Control Base
to allow it to operate with existing 9-pin Wet Cell As-
semblies.
Interchangeable Flow Cell Assemblies are available as
follows:
• Piston Cell (1 to 5 LPM)
• Low Flow Wet Cell (1 to 250 cc/m)
• Standard Flow Wet Cell (20 cc/m to 6 LPM)
• High Flow Wet Cell (2 to 30 LPM)
1.2 THEORY OF OPERATION
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 2. The
volume (V) is measured volume of space between
two infrared sensors. The time (t) is that interval
needed for an object (soap film bubble or piston cell
piston) to travel between the two sensors which
bound the volume. Thus, the volume per unit of time
(V/t) becomes the flow rate. Because the electronic
clock is far more accurate than the volume measure-
ments, the volume measurement accuracy determines
the overall accuracy of the unit.
The Gilibrator 2 consists of two elements, the Flow
Cell Assembly (either Wet or Piston ) and the Control
Unit Base. The function of the Flow Cell Assembly is
to provide a means for measuring an object (soap film
bubble or piston cell piston) traveling up a flow tube
through a known volume of space.
Measurement of the travel time is done by means of
“top” and “bottom” infrared sensor pairs mounted
along the flow tube. The volume bound by these sen-
sors is set accurately to a primary volume standard.
As the object (bubble or piston) moves up the tube, it
trips the bottom sensor pair. As it moves further up
the tube, it trips the top sensor pair. The time differ-
ence between the bottom and top sensors becomes
the elapsed travel time. This timing information (along
with the volume information) is sent to the micropro-
cessor in the Control Unit Base. The calculated flow
and sample information are then displayed directly on
the Liquid Crystal Display.

SECTION TWO
COMPONENTS
2.1 CONTROL UNIT
The Control Unit (refer to Figures 2.1 & 2.2) contains a
crystal-controlled microprocessor timing system. This
type of microprocessor, used in conjunction with the
built-in software, provides an extremely accurate
method for calculating the flow rate parameters.
The Control Unit contains the following components:
2.1.1 Buttons & Indicators
The ON and OFF buttons turn the Control Unit on and
off.
The DELETE/RESET button has three functions:
Pressing for 1 second deletes the most recent read-
ing from the running average. It resets the average
and sample number to the previous reading. If a
printer is connected, a minus symbol is printed and
the average returns to the previous value. If a com-
puter is connected a minus symbol is displayed on the
computer monitor and the average returns to the pre-
vious value.
Pressing for 3 seconds resets the current readings to
zero and initiates a new sampling sequence. If a
printer is connected, it prints a new header. If the
Flow Monitoring Software is running, its graph will
clear and a new sampling sequence will start.
Pressing simultaneoulsy with the ON button sets
the sample size.The sample size is adjusted in 5
sample increments by repeatedly pressing DELETE/RE-
SET (ragne: 5–95).
Charge Indicator
This LED lights up when the batteries are charging.
2.1.2 Display Characters
FLOW
This shows the flow rate in either cubic centimeters
per minute (ccm) or liters per minute (lpm) depend-
ing on the Flow Cell Assembly used.
AVERAGE
Shows the average flow rate for the samples taken.
SAMPLE #
Shows the number of samples taken (MAX = 99).
LOW BAT
This warning is displayed if insufficient battery charge
remains to operate the unit properly. If the battery is
not recharged, the unit automatically shuts off shortly
after this message appears.
NOTE
Batteries must be fully charged for unit to function
properly.
WAIT
Indicates there is a flow measurement in progress.
ERROR 1
Indicates trouble with the Flow Cell connection or ad-
justment.
ERROR 2
If this message appears call the factory.
2.1.3 Interface Components
Charging Jack
A 2.1 mm barrel jack that supports a standard AC/DC
charger/adapter. With the charger/adapter the unit can
be operated while continuously plugged into an wall
socket. Or, the charger can be used to charge the unit
overnight (14 hours) prior to operation in the field.
Printer Jack
A 25-pin printer connector allows the unit to be con-
nected to: a) a Thermal Printer, b) a PC compatible
dot-matrix or ink jet printer, c) an PC computer. The
jack connects to a printer using a standard DB-25 to
Centronics printer cable. A Gilibrator 2 Flow Monitor-
ing Software Kit is available. The kit includes an oper-
ating manual, special cable, and software.
Cable Assembly
The 9-Pin or 15-pin cable assembly connects to the
Connecting Jack located on the back of the flow cell as-
sembly. On piston cell assemblies the cable directly
connects to the cell assembly 15-pin jack. Wet cell as-
semblies require a 15-to-9 pin adapter.
NOTE
Onlynon-CE ControlBaseswith 15-Pincable assemblies
can be used with Piston Cells.

2.3 WET CELL ASSEMBLY
The Wet Flow Cell Assembly (refer to Figure 2.4) con-
sists 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.
The bubble is carried by airflow from the bottom to
the top of the tube. As the bubble moves past two in-
frared sensors, each sensor transmits a signal to the
Control Unit indicating the passage of the bubble film.
A manual push-button on the Flow Cell Assembly
starts the bubble film on its travel up the tube.
Wet Cell Assemblies come in three sizes and can be
used with both CE and non-CE Control Base Units:
• Low Flow (1 to 250 ccm)
• Standard Flow (20 ccm to 6 lpm)
• High Flow (2 to 30 lpm)
2.3.1 Bubble Generator Components
The Bubble Generator uses a special soap solution to
generate the bubbles. This specially compounded low
residue soap is designed to provide high film strength
and compatibility with the materials used in the Flow
Cell Assembly.
WARNING
OnlyuseSoap SolutionPartNo. 800450withtheWetCell
Assembly. Use of other soap solutions can damage the
Flow Cell.
Pulsation Damper
This built-in damper smooths out any pulsation within
the airflow and reduces oscillation of the bubble film
assuring maximum accuracy.
2.2 PISTON CELL ASSEMBLY
The Piston Cell Assembly (refer to Figure 2.2) is a
single unit that need not be disassembled and requires
very little maintenance. The assembly contains a preci-
sion cylinder-piston assembly.
A green Ready Light on the side of unit signals when
the unit is ready and sampling may begin.
A Bleeder Valve located on top of the cell assembly is
closed to provide the vacuum necessary to move the
piston up the tube.
Secured to the flow tube and secured between the up-
per and lower portions of the cell assembly, is the
Sensor Rail (refer to Figure 2.3). The Sensor Rail in-
cludes lower and upper infrared sensors used to time
the movement of the piston through the flow cell.
The movement of the piston up and down the flow
tube provides the means for calculating an accurate
flow rate. As the piston moves past two infrared sen-
sors, each sensor transmits a signal to the Control Unit
indicating the passage of the piston.
Pulsation Damper
This built-in damper smooths out any pulsation within
the airflow and reduces oscillation of the piston assur-
ing maximum accuracy.
The Piston Cell Assembly has a flow rate range from
1 to 5 LPM.
IMPORTANT NOTE
CE approved Control Unit Bases have 9-Pin cables and
CANNOT be used with Piston Cells. Non-CE Control Unit
Bases have 15-Pin cables and can be used with Piston
Cells.

2.3.2 Sensor Block
Surrounding the flow tube and secured between the
upper and lower chamber of the bubble generator, is
the Sensor Block (refer to Figure 2.4). The block in-
cludes lower and upper infrared sensors used to time
the movement of bubbles through the Flow Cell. This
block is secured to the Bubble Generator Assembly
with two locking screws, allowing easy removal of the
Sensor Block for Flow Cell maintenance.
Bubble Initiate Button
This push-button lowers the Bubble Generator Ring
into the soap solution reservoir. When the button is
released, the ring lifts out of the soap solution and a
film bubble is generated across the opening of the
flow tube.
Bubble Breaker
The Bubble Breaker is a secondary chamber in the
upper section of the flow cell that provides the travel-
ing soap bubble a rapid expansion path. This is instru-
mental in breaking the bubble. It also prevents exces-
sive wall wetting by the soap film and allows it to
flow back into the base of the cell.
Storage Tubing
The anti-spill storage tubing connects the upper and
lower cell chambers and prevents the soap solution
from evaporating. Evaporation can may cause the
soap solution concentration to change.
CAUTION
If transporting a Wet Cell Assembly by plane, be sure to
disconnect the Storage Tubing from either the Air Outlet
Boss (upper) or Air Inlet Boss (lower). This prevents the
Flow Cell Assembly from becoming pressurized and
possibly causing a rupture within the Bubble Generator.

SECTION THREE
SETUP
3.1 SYSTEM SET-UP
This section describes the steps necessary to set up the
Gilibrator 2 Calibration System. This includes initial
setup, mounting the Cell Assembly, connecting the ca-
bling, adding soap solution to wet cell assemblies, and
setting up the sampling source. Figure 3.1 shows how a
complete Gilibrator 2 Calibration System may be con-
figured.
Prior to setup make certain you have properly con-
nected the battery charger to the Charger Jack in the
Control Unit) and to an appropriate AC wall outlet. If
the charger/adapter is properly connected, the Charge
Indicator should light up.
If you plan to use the Gilibrator 2 in the field, make
certain the unit is fully charged (at least 14 hours) be-
fore operating the unit. If you plan to use the unit in
the lab (i.e., near an AC wall outlet), you can continue
with setup and operation immediately.
IMPORTANT COMPATIBILITY NOTE
Most flow cells designed for the original Gilibrator base
are compatible with your new Gilibrator 2 base unit. If
your existing flow cell is not compatible with the Gilibra-
tor 2 base, the unit will display a false SAMPLE# reading
immediatelyafterstart-up.Ifthishappens,your flowcell
needs to be returned to Sensidyne to be upgraded. See
Appendix C (page 30) for more information.
3.2 CELL ASSEMBLY SET-UP
3.2.1 Cell Assembly Mounting
Refer to Figures 3.2 & 3.3. Perform the following steps
to mount the Cell Assembly.
CAUTION
Always mount or remove the Cell Assembly by grasping
and rotating only the lower part of the assembly.
1) The Control Unit Base should be positioned on a
flat, level surface.
2) Select the appropriate Cell Assembly (Piston, Low,
Standard, or High).
3) Grasp the lower portion of the Cell Assembly and
move it to the Mounting Plate on the Control Unit.
4) With the front of the Cell Assembly facing right

3.2.2 Cabling Connections
IMPORTANT
Turn off the unit before connecting any cables.
If you are using a Piston Cell Assembly, insert the 15-
Pin Interface Plug directly into the Connecting Jack lo-
cated on the back of the Piston Cell (refer to Figure
2.3). Be sure to properly match up the connectors be-
fore engaging.
If you are installing a Wet Cell Assembly on a 15-Pin
Control Base, insert the 15-Pin Interface Plug from the
Control Base into the 15-to-9 pin adapter. Insert the
adapter into the Connecting Jack located on the back of
the Wet Cell (refer to Figure 2.4). Be sure to properly
match up the connectors before engaging.
If you are installing a Wet Cell on a 9-Pin Control Base,
insert the 9-Pin Interface Plug from the Control Base
directly into the Connecting Jack located on the back of
the Wet Cell (refer to figure 2.4). Be sure to properly
match up the connectors before engaging.
Connect the appropriate optional printer (or computer)
cable to the Printer Jack located on the left side of the
Control Unit. Make certain the cable and Printer Jack
connectors match up before making a complete con-
nection. Once the cable has been properly connected,
turn on the printer (or computer) and make certain it is
prepared to receive data before turning on the Gilibra-
tor 2 unit.
3.2.3 Adding Soap Solution (Wet Cell only)
WARNING
Only use Soap Solution Part No. 800450 with the Flow
Cell Assembly. Use of other soap solutions can damage
the Flow Cell.
Add soap solution to the unit as follows:
1) Remove the Storage Tubing from the Air Outlet
Boss (see Figure 2.3) of the Flow Cell. Fill the dis-
penser bottle provided with Gilibrator soap solu-
tion. Using the rubber Storage Tubing as a funnel,
slowly add soap solution from the dispenser (refer
to Figure 3.4).
2) The amount of soap needed is determined by de-
pressing the Bubble Initiate Button 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 is immersed
in the solution.
CAUTION
Do Not Overfill.
3) After filling is completed, the rubber Storage Tub-
ing may be removed completely. Recap the soap
dispenser bottle for later use.
NOTE
If the Wet Cell Assembly is not going to be used for an
extended period of time, reinstall the rubber Storage
Tubing between the inlet and outlet bosses. This pre-

WARNING
If you are shipping the Wet Cell, you must remove the
rubber Storage Tubbing between the inlet and outlet
bosses.
3.2.4 Sampling Source Connection
Connect the air sampler to be calibrated to the Air Out-
let Boss of the Wet Cell Assembly or the Inlet Tube on
the Piston Cell Assembly. Use 1/4” ID tubing in either
case.
