3. Attach the rotameter to the debubbler outlet.

CAUTION
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
2-2.

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