INSTALLATION & OPERATIONS MANUAL
FOR SIGHT FLOW INDICATORS
** IMPORTANT: Not Recommended For Steam Service Applications.
STORAGE AND HANDLING
All units should be inspected for damage upon receipt in case it may be necessary to
submit a claim to the carrier. Units should be stored where they will be protected
from the elements and corrosive fumes. Proper storage should ensure that damage
resulting from impact is completely avoided. Care should be taken to protect the end
connections from damage. Under no circumstances should the glass ever have
objects placed on top of it or be struck by other objects.
INSTALLATION INSTRUCTIONS
All units should be checked to ensure that they contain no foreign matter and that the
end connections are clean, undamaged, and in line with the adjoining pipe. Using a
flashlight, examine the glass carefully for any indications of scratches or cloudiness,
if any type of flaw is apparent, the unit must not be installed until the glass has been
replaced.
Prepare proper supports to ensure that pipeline stresses will not be transmitted to the
sight flow indicator. Any misalignment between adjacent connections must be
corrected rather than forcing a fit-up. Large, heavy units must be independently
supported to avoid stressing the piping. Be certain that the installation location
provides access for comfortable viewing and maintenance. Keep in mind that the
units must be placed so that damage cannot be inflicted by passing traffic.
Considerations should be given to locations where the glass will not be subjected to
extreme temperature variations. For instance, an indicator must not be placed in a hot
process line where the opening of a door could inflict sudden blasts of cold air. Cold
“wash down” water is also a frequent enemy of glass in hot pipelines. A poor choice
of installation could impose conditions of thermal shock (I.E. rapid heating) where
the stress values approach twice those caused by temperature alone and are additives
to mechanical stresses caused by pressure and bolting loads.
