4.3.5 ORBISPHERE flow chambers

The ORBISPHERE 32001.xxx flow chambers are used to draw liquid samples past the sensor.
They are available in several materials, depending on the application.
They connect to 6-mm or ¼" stainless steel tubing by means of two Swagelok™ fittings. If
necessary, copper or plastic tubing with low permeability can be substituted. Stainless steel
tubing is normally enough to hold the assembly in place, but for a more stable installation, a
large U-bolt can be used to mount the flow chamber to a support.
The connection diagram below is a recommended installation that allows for measuring and
calibrating without having to disconnect a line manually. "A" and "B" represent 3-way valves.
For measuring, calibration gas inlets and outlets are shut off. During calibration, the flow is
reversed to drive the remaining sample out. The calibration gas enters at the "sample out" port
and exits at the "sample in" port, as shown.
