The Fluid Components ST50 Flow Meter is an accurate, easy to install, no moving parts solution for measuring and controlling air, compressed air or 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" (51 to 610 mm) with 1/2" or 3/4" NPT.
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.
