Piping procedure

Piping for sample inlet

Provide a valve to stop and control sample flow.

Take sample water from the constant flow line. If the flow rate is variable, select RA-10
over flow tank built-in or RA-20 with a constant flow valve to be constant flow through the
measurement cell.

Provide a filter cartridge (100

m optionally available) if the sample includes dirts or
suspended solid.

Use hard PVC pipe for sampling and the sampling length should be short as possible.

Sample water can not be frozen. If the sample might be frozen, provide a countermeasure
for freezing to the sampling pipe and measurement cell.

Piping for sample outlet (in the case of RA-10)

Proper piping procedure

(1) Make the piping end open-air and minimize the piping length so that no back pressure
is applied.

(2) If the distance to the drain becomes long, provide an open-air portion and horizontally
carry out piping with a pipe of 20 A or larger.

(3) Carry out piping at falling gradient with no horizontal piping at right angles (piping: 16
A or larger).
CAUTION
Sample inlet to the flow control valve may be pressurized, careful pipe works are required to ensure
safe sealing.
