The Control unit also supports a hard copy print out through the use of a printer accessory-. Section 2 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. A. Bubble Generator 1) Flow Ranges Low Flow : 1 t o 2 5 0 cclmin.

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. b) A s t h e b u b b l e t r a v e r s e s b e t w e e n t h e s a n s o r s , f i r s t o n e a n d t h e n t h e second, sensors are tripped thereby providing the time for the bubble This timing information is sent to the micro processor of the traverse. control base which in turn provides the crystal control time base for the T h e t i m i n g i n f o r m a t i o n a l o n g w i t h t h e volu,me i n f o r m a t i o n a r e t h e n system. 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. Section 4 Operating Procedures 1. Initial Set-up This covers all steps necessary to bring the Gilibrator into This includes charging, cell mounting, installing operating status. soap solution, connecting the printer (optional) and connecting the sampling source. A) Charging the Gilibrator 1. Prior to operation, plug the 120V charger into the wall and connect to the Charging Jack (13) on the right side of the Control Unit. The unit’s Charging LED (11) will light indicating that the unit is charging properly. Allow the battery system to charge for 14 hours prior to operation.

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. D) Printer Connection (if applicable) 1. Connect printer cable to Printer Jack connector (18) on the left side of the Control Unit. Be sure to properly match up connectors before engaging. 10 Bubble Initiate Bubble Gel Solution Res E) C o n n e c t the Sampler 1.

After the Flow Tube walls have been “primed”, turn on the Power Switch (12) of the Cilibrator Control Unit (base) and the Printer M o d u l e i f o n e i s b e i n g u s e d . Wait approximately 10 seconds while the system runs through it’s check sequence. The Run LED (20) will light at this time as well as a Lo Battery indication and a series of five dashes displayed on the LCD Readout (19). Do not operate the Cilibrator until the Run LED signal extinguishes. Ready operation is indicated by a series of 4 dashes. C) Bubble Generation depress the Bubble Initiate 1. For optimum bubble generation, Button (22) and hold to initiate 1 bubble up the flow tube. Release the button to initiate a second bubble up the flow tube. This will be the standard procedure to making clean, consistent bubbles at High and Medium flow ranges. 11 2 .

The timing information is then transmitted to the control unit which will perform all the necessary calculation. A flow reading will instantaneously appear on the LCD display (19). However, if a bubble breaks before the time sequence is completed, timing will continue until another bubble is generated to trip the second sensors. This will cause an erroneous reading and should be subtracted from the average by hitting the Delete Button (16). If a Printer Module is used, be sure Led i t ’ s p r i n t i n g s e q u e n c e b e f o r e p r e s s i n g the Delete Button is activated, a negative ed on the LCD of the Control Unit and a’line showing this subtraction. t h e p r i n t e r h a s complethe Delete Button.

Repressing the button will display the number of samples accumulated for that averaging sequence and releasing will once again display the last flow reading. Additional pressing and holding will repeat this sequence. 2. Delete (16) - To delete obvious false readings, push the Delete Button which will automatically delete the false information from the average and reset the average and sample number back to the previous reading. 3. Reset (17) - To reinitiate the sequence for additional pumps, h i t t h e R e s e t B u t t o n . This will zero out all sample and average registers within the Control Unit and will cause the printer to i n d e x oneline and reprint sequence headings. This denotes the start of a new sequence. The Reset Button is also used if a malformed bubble is generated and has not been been subtracted f r o m t h e a v e r a g e byuse o f t h e D e l e t e F u n c t i o n . 12 Section 5 Storage t Maintenance 1.

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. 4.

The Printer Module will print for the current calibration i n d i c a t e d a f t e r t h e identificaSee sample below. b. Initiate a bubble up the Flow Tube:and observe the reading on the Control unit and also on the Printer Module. 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. 2 .

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 a) Storage (Daily Take Down) 1. Turn the Power of the Printer Module OFF. All data stored in the printer cannot be reviewed once this is done. 2. Turn off the Power of the Control Unit. 3. Turn off the Power of the Sampler being calibrated. b) Storage (Long Term) - I f t h e P r i n t e r M o d u l e i s n o t t o b e u s e d f o r long periods of time, the following steps should be taken to keep the unit in proper working order. Disconnect the interconnect cable from the Control Unit and 1. from the Printer Module. 2. Store in original packaging or carrying case. c) Cleaning - Use a damp cloth with warm ACETONE or any other harsh cleaners. water.

Operational Features D i r e c t F l o w R e a d i n g s - The easy to read LCD read-out on the Control Unit (base) instantly displays flow readings. Auto Averaging - A switch on the Control Unit provides Auto-Averaging of the successive flow readings. Flow Delete Function - A Flow Delete switch allows the user to delete erroneous flow readings from the Auto-Averaging function. For example, if a double bubble or other obvious malfunction is observed, that reading can be subtracted from the auto-average and will automatically reset the average to it’s previous value. Programmable Update - The micro-processor electronic design allows programmable updates to assure a long useful service life. Mechanical Features Pulsation Damper - The pulsation damper removes pulsation from the flow source for higher accuracy sampling as well as eliminating pulsations back into the flow source during bubble generation. i Ring Bubble Generator - The Ring Bubble Generator lifts an even soap film from the soap reservoir and provides consistent bubble generation. . Bubble Breaker - The Bubble Breaker design allows the soap film to be drawn away form the end of the flow tube before bursting.
