OPERATION MANUAL
Rev. 004 MAY 2015
Process connections are fitted to the rear of the analyzer, #1 in Figure 6a below. Process water is fed in through the
lower process inlet into the measurement chamber (#8) and flows out through the upper process outlet, as indicated by
the red arrows in Figure 6b below. The standard unit configuration consists of a valve assembly (#4 Valve, #5 Actuator
and #6 valve controller), chamber assembly (#8 chamber, cover and connecting pipe work) and sample point (#9).
At the flow outlet a sample point is fitted which terminates, as standard, in a ½” NPT valve (#9) from which samples can
be taken for lab analysis. The measurement chamber is fitted with a viewing window covered by a removable window
cap (#8). The valve assembly fitted to each unit uses a valve controller (#6) to operate the flow valve (#4)
Each unit is fitted with a valve controller to regulate valve position via a pneumatic (fitted as standard), or electric
(optional), actuator controlling the flow of process water into, and out of, the chamber.
