3.1 Installing the wet-section
3.1.1 Sample requirements
Ensure the sampling point is as close as possible to the
wet-section and provides a thoroughly-mixed representative
sample.
Sample must contain less than 10 ppm suspended solids
with a particle size no greater than 60 µm. (If particle sizes
exceed 60 µm, use a 60 µm filter.)
Sample temperature must be within the range 5 to 55 °C
(41 to 131 °F).
Sample flow rates must be within the range 100 to 400
ml/min (6.10 to 24.4 to cu in./min.).
Sample must not exceed 1.5 bar gauge (21.75 psi).
3.1.2 Location
For general location requirements refer to Fig. 3.1. Install in a
clean, dry, well ventilated and vibration-free location giving easy
access. Avoid rooms containing corrosive gases or vapors, for
example, chlorination equipment or chlorine gas cylinders.
Select a location away from strong electrical and magnetic
fields. If this is not possible, particularly in applications where
mobile communications equipment is expected to be used,
screened cables within flexible, earthed metal conduit must be
used.
The standard solution and reagent containers are mounted at
the top of the wet-section panel. Standard solution containers
are connected via quick-disconnect (QD) couplings. If the
transmitter has to be mounted directly above the wet-section,
allow at least 270 mm (11 in.) separation between the two units
for access to solution containers.
