Criteria (2) for installation location
Installed position
Install the instrument at a place where the measured fluid always fills inside the detector. An
example of installation is shown in the figure below to illustrate this condition.
The fluid
may not fill
completely.

Fig. 2-1. Example of installation
Note) Install the instrument under the condition marked by a circle in the figure above with the
detector filled with the fluid in full. If the detector is not filled in full, output errors may
result. If empty, output fluctuations may result.
If the measured fluid is highly viscous, we recommend installing the instrument on a
vertical pipe and flowing the fluid to ensure an axially symmetrical flow.
Arrange a straight pipe section upstream and downstream of the installed place. For the
straight section length, see the figure below.

(Less than 15
degrees can
be deemed to be a
straight section.)
