FCI Flow Meters may be installed with less than the recommended straight run, but may have performance limitations. FCI offers
VORTAB flow conditioners for use in applications that have significant straight run limitations. FCI uses the AVAL application
modeling software to predict meter performance in each installation. AVAL outputs are available to review prior to order placement
and will indicate performance expectations both with and without flow conditioning.
Flow Element Installation
Warning: The element is shipped specifically installed in the TEE oriented for inline installation. DO not remove the
sensing element from the TEE section during installation as calibrated performance can be effected.
Process Connections
The ST75 is available in pipe Tee configurations with NPT threads and tubing tees with a compression fitting suitable to clamp down on
concentric smooth surface tubing. The pipe Tee versions are standard 150# class rated tees suitable for service up to 150 PSIG at the
process temperature maximum of 250°F (121°C). The compression fitting material offered in the tube type configuration is rated for
250 PSIG service.
Pipe Tee Installation: With pipe extensions properly cut to length and the appropriate sealing materials used on the threads, install flow
element section by slowly rotating the configuration until firmly secure on the pipe section. Complete by installing opposing end pipe
section using care to firmly secure the element assembly either in a top mount or side mount position.
Tube Tee Installation: Clean all mating surfaces of the tee fitting, ferrules and the flow tube. Insert the flow tubing into the tee fitting.
Make sure the tubing rests firmly in the fitting counter bore seat. Tighten the nut on both ends of the tee by hand. Hold the fitting body
steady with a backup wrench, tighten the fitting nuts 1-1/4 turns, from hand tight baseline.
The ST75V is available in with flow tube configurations offering male and female NPT threads, ANSI flanges and DIN flanges. The
flow tube assemblies are rated for service up to 240 PSIG at the process temperature maximum of 250°F (121°C).
NPT Flow Tube Installation: With pipe extensions properly cut to length and the appropriate sealing materials used on the threads,
install flow element section by slowly rotating the configuration until firmly secure on the pipe section. Complete by installing opposing
end pipe section using care to firmly secure the element assembly either in a top mount or side mount position.
Flanged Installation: Clean all mating surfaces. Install appropriate sealing gasket between mating flanges. Tighten flange mating hard-
ware to meet system sealing requiments.
