ATI A15/66 Residual Sulfite Monitor

O&M Manual

Rev-W (8/10)

SAMPLE INLET OVERFLOW

The water sample supplied to the monitor is connected to a special overflow chamber. This is

done to insure that the sample flowrate to the monitor is sufficient to insure that fresh sample is always

available at the sample pickup point. Most of the sample flowing to this assembly will simply go directly to

the drain.

Figure 10 shows the sample overflow assembly on its aluminum mounting bracket. The bracket

is supplied to hold the inlet assembly under the sample pump, and to allow waste from the chemistry

module to flow back into the drain chamber. The overflow assembly should be mounted close to the

chemistry module (as shown in figure 10) to minimize system response time. Mounting further from the

chemistry module will increase the sample transport time, thereby increasing the monitor response time.

Once mounted, the sample pickup tube should be placed into the inlet chamber and the chemistry

module drain tube should be placed into the drain chamber as shown.
