2.1.2 System without Head Tank and Zero Turbidity Filter
This is a simple system where a water sample is taken from the process and directly introduced
into the detector. This system configuration can be used when a water sample contains a negligible
amount of air bubbles or when the turbidity of a water sample is high and the effect of air bubbles is
nonsignificant.
CAUTION
Sample water conditions and ambient temperature must meet the specifications: maximum pressure:
500 kPa; sample temperature: 0 to 50°C; ambient temperature: -5 to 50°C.

Process Piping
Figure 2.2 Piping Diagram
• The flow control should not be done on the inlet side of the detector.
• To prevent corrosion inside the zero turbidity filter, allow water to flow through the filter and flow
out from the zero water drain valve continuously at a flow rate of approximately 10 ml/min.
