6.1 – DUAL SYSTEM OVERVIEW
The OIW EX Side Stream series of analyzers may be fitted with 2 flow valves to facilitate the analysis of 2 different
sources of produced water by a single analyzer unit. The inflow pipe on the chamber assembly is fitted with a ‘T’ piece,
as shown in Figure 92, which connects an additional flow valve for the second process line.

When an additional flow valve is fitted only one stream at a time can be analyzed. The flow valves are controlled by the
OIW software. The software is configured to open and close each valve in turn as required. Figure 93a shows the
process flows when flow valve 1 is open and then, in figure 93b, when flow valve 2 is open.

NOTE: Both valves cannot be open at the same time.
