ST50 Insertion Flow Meter for Air, Compressed Air and Nitrogen
Mass Flow Meter SummaryThe ST50 Flow Meter is an accurate, easy
to install, no moving parts solution for measuring and controlling
air, compressed air and nitrogen flow. ST50 utilizes FCI proven
thermal dispersion technology to provide direct mass flow
measurement resulting in higher performance at a lower cost than
orifice plates, DP, Vortex shedding and other thermal devices. The
meter installs in line sizes ranging from 2 to 24 inches [51 to
610mm] with 1/2" or 3/4" NPT.
The ST50 uses precision, lithography structured platinum RTD sensors
embedded in FCI's equal mass small diameter, all metal thermowells.
Combined with microprocessor electronics and precision calibration,
the ST50 achieves excellent accuracy, fast response and virtually
maintenance free operation.
