2.3Installation – Debubbler Assembly
See Figure
Connect the sample line to the inlet fitting. The fitting accepts
Attach a piece of 3/8 inch ID soft tubing to the drain fitting. The debubbler must drain to atmos- phere.
NOTE:
During operation, the debubbler is under pressure. A 0.040 inch (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.
WARNING
Before removing the sensor, be absolutely certain that the process pressure is reduced to 0 psig and the process temperature is lowered to a safe level!
The amount of pressure in the debubbler can be estimated from the flow rate. See Table
To control and monitor sample flow, a valved rotameter with fittings is available (PN
