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.
