Installation Precautions

Any questions with respect to the installation should be addressed prior to beginning the installation. Failure to install
the Sentinel correctly can increase measurement uncertainty.
CAUTION!
All the mechanical and electronic components are shipped fully assembled (see Figure 1 on page xi), however the
following precautions should be observed:
• Make sure the difference between the inside diameter of the pipe and that of the Sentinel spoolpiece does not
exceed 1%. Changes in internal diameters will cause flow profile disturbances.
• Make sure any non-symmetrical offset does not exceed 1%. Misalignment between the piping and the
spoolpiece may cause flow profile disturbances.
• Make sure the gasket is centered on the flange faces and does not protrude into the pipe. Protrusion of the
gasket into the pipe may cause flow profile disturbances.
• Make sure the Sentinel is oriented with the flow transmitter in a vertical position at the top (see Figure 10 on
page xxiii).

To avoid possible strain, refer to the Sentinel label for the assembly weight, use a
properly-rated lifting assembly, and place the lifting straps in the indicated locations
(see Figure 8 below).
