2. UNPACKING AND CHECKING
2-1. Unpacking and inspection
When you receive the PR20 retrac-
table fitting it is packed in a card-
board box. Open the box and
check that the model code on the
fitting is the same as on the pac-
king list (see §2-4). The model code
with serial number of the fitting are
on an identification plate fixed on
the protection ring.
Also check that the options you
ordered are supplied. These options
are delivered in separate bags.
If you have any problems or
questions, please contact the
nearest Yokogawa service centre or
sales organisation for assistance.
2-2. Mounting location
The PR20 fitting is intended to be
used for in-line pH measurement.
When it is delivered with an optional
ball-valve or when it is used in com-
bination with a locally purchased 1
inch ball-valve, the process does
not need to be interrupted for main-
tenance of the sensor. The location
can be in a large diameter pipeline
or a vessel. The angle of the fitting
with the horizon should not be less
than 15 degrees (see fig. 2-1).
The pressure- and temperature
ratings of the electrode inside the
fitting determine the maximum
rating of the measurement point.
