27. Appendix 8. Flow Through Cell
The AP-5000 Flow Through Cell (Flowcell) is designed for use with most third party
pumping devices.
The Flowcell allows sample water to flow up through the AP-5000, passing over all the
individual electrodes simultaneously. This eliminates air contact with pumped samples from
groundwater boreholes allowing truly representative measurements to be obtained.
Made from marine grade aluminium, the Flowcell is ruggedly constructed for hard use in
the field. The base flange includes four holes to allow the unit to be pegged down if
necessary.
27.1. Spigot Installation
The AP-5000 Flowcell is supplied with two pairs of spigots, one pair to fit 6mm (1/4”) ID
tube and one pair to fit 10mm (3/8”) ID tube.
The spigots have a tapered thread so should be screwed into the inlet and outlet holes of
the Flowcell until they are tight. At this point, they should seal due to the taper. If a spigot
will not seal properly, remove it then re-insert with some PTFE plumber’s tape wrapped
around the thread.
27.2. AP-5000 Preparation Prior to Use
In order to fit the AP-5000 into the Flowcell, it is necessary to first fit the Flowcell Adapter
Ring.
Referring to the photographs on the right, first
remove the sleeve from the AP-5000.
Next, slide the Adapter Ring onto the main
body of the AP-5000. The blue section of the
AP-5000 with its O ring should fit snugly into
the recess in top of the Adapter Ring.
Finally, re-fit the sleeve. As you tighten the
sleeve up, it will pull the body of the AP-5000
into the Adapter Ring and form a seal against
the O ring.
The photograph on the far right shows the
complete assembly.
Now fit the Sleeve End Cap and calibrate any
optical electrodes fitted to the AP-5000.
It is essential to re-calibrate the AP-5000's
optical electrodes AFTER the Adapter
Ring has been fitted to ensure correct
performance. This is especially important
for Turbidity measurement.
