Piping

Flow
Piping from 15 A to 20 A is suitable for the detector. If the turbidity and flow rate are low,

6 mm black nylon tube can be used. For the detector, be sure to run sample water
upward from the bottom. The flow rate of the sample water flowing to the measurement cell
should be within a range from 0.5 L/min to 10 L/min.
Install valve V-2 for flow rate adjustment at the outlet of the detector. When the sample water
is supplied in-line, closing this valve allows measurement to be performed while maintaining
the pressure. This makes it possible to suppress the formation of air bubbles inside the
detector.
Install manual ball valve V-1 at the shortest distance possible from the inlet of the detector.
Collect the calibration solution by operating this valve.
Install three valves, which are V-3 for sample water, V-5 for zero water, and V-4 for drain, in
the forward direction of valve V-1.
Moreover, for sample water that may easily contaminate piping, it is recommended that you
provide air piping so that the sampling piping can be cleaned from the opposite direction.
Install a check valve for the air pipeline to prevent reverse flow.
If tap water is used for zero water and cleaning water, collect the water using a water receiving
tank and send the water using a pump to prevent contamination by reverse flow. It is
recommended that you provide a check valve for this pipeline as well.
For low-turbidity sample water (e.g., tap water, swimming pool water), use the sample water
filtered with an ultra filter as zero water. Perform zero calibration while running zero water
without accumulating it.
