1.1 Cleaning Sensor
Flow Chamber
☞
☞
1.
Open the Model 8320 sensor enclosure door to access
the flow chamber.
2.
After draining the sensor, remove the flow chamber
cover by turning it 1/8 turn counterclockwise to disen-
gage its four tabs, and lift it straight off the chamber.
NOTE:
For high pressure design sensor (Figure 4-2),
remove flow chamber cover lockring and win-
dow by unscrewing lockring counterclockwise.
3.
Remove the baffle assembly. It is “keyed” with a slot
and guide rib on its left side to fit only one way in the
flow chamber.
NOTE:
The high pressure design sensor uses the same
baffle assembly, but this assembly is “keyed” with
a rod and hole -- not a slot and guide rib.
4.
Wipe the inside surface of the flow chamber with a soft,
clean, damp cloth.
