3.2 Plumbing

The recommended plumbing for the instrument is shown in Figure 4. The instrument is

designed to require very little head pressure to operate; around 6.9kPa (1 PSI). The flow

through cuvette is rated for a flow of 100ml/min. – 1 liter/min. (0.026-0.26Gal/min). The

integral pressure regulator is rated for a maximum pressure of 1380 kPa (200 PSI.). The

maximum allowable fluid temperature is 50°C (122°F).

Figure 4: Recommended Plumbing for the Instrument

The instrument is equipped to be plumbed using 4.75 mm (3/16”) ID, 8 mm (5/16”) OD

flexible tubing. Opaque tubing should be used if the tubing will be exposed to sunlight, to

prevent algae growth.

In figure 4, there are two flow devices shown. The one on the input side is a shutoff clamp

used during cuvette maintenance. The other device is a backpressure valve. Backpressure

may be required to prevent air from coming out of solution, which may be observed as

tiny air bubbles.
