7.3 Sensor Installation Guidelines
The following are general installation guidelines and recommendations
for installing a SONARtrac
TM sensor.
•
Where necessary, get a Hot Work Permit prior to installation of
system.
•
Select locations with well-developed flow profiles.
•
Avoid installation locations directly after piping configurations that
cause flow jetting.
•
Install flow sensor upstream of control valves, “T”s, orifice plates,
and any other severe source of flow disturbance.
•
Locate the sensor upstream of pipe taps such as those used for
temperature and pressure sensors.
•
Good piping practices are required near flanges. This includes
good alignment of pipes, and properly sized and installed gaskets
that do not disturb the flow profile.
•
Contact your local distributor or CiDRA Technical Support if you
have questions.
7.4 Process Piping Considerations
The SONARtrac
TM
sensor head assembly mounts on the process
pipe. There is no need for breaking any process connections or for
shutting down the process. The sensor head must be installed in a
location that ensures a full pipe during operation.
