SampleRequirements
The constant head flow controller can adapt to changing sample flows between 10 and 80 gal/hr
(40‐300L/hr).
Minimumflow:10gal/hr(38L/hr)
SamplePressure:1to30psig(0.1‐2bar)
Temperature:32°to122°F(0°to50°C)
MountingandConnec
tingtheInletandDrainfitting s
The FCA‐22 is intended for wall mounting only. The sensors insert into the flow cells as shown in the
figures. A ¼” barbed fitting is provided for the sample inlet. If desired, a ¼”compressionfitting can be
used.Th
esample inlet is ¼” FNPT.The sample drains through the¾” FNPT holeatthe bottom ofthe

PoweringtheC‐22
Attach power as described in the C‐22 manual.Tighten the cable glands provide a good seal to the
cable.
