Reading errors
During operation, the debubbler is under pressure. A 0.040 in. (1
mm) orifice in the outlet provides the pressure. Back pressure helps
prevent outgassing, which can lead to bubbles accumulating on the
sensor face, resulting in erroneous readings.
Do not exceed 30 psig (308 kPa abs) inlet pressure.
The amount of pressure in the debubbler can be estimated from the
flow rate. See
Table 1-2: Approximate Debubbler Pressure as a Function of Flow
(0.040 Inch Outlet Orifice)

To control and monitor sample flow, a valved rotameter with fittings
is available (PN 24103-00).
3. Attach the rotameter to the debubbler outlet.
You can also use the rotameter to increase back pressure on the
debubbler if additional pressure is needed to prevent outgassing.
