FCI ST50 flow meter

Click2Contact

The ST50 flow meter uses FCI’s highly accurate thermal dispersion mass flow sensing technology to provide highly effective direct mass flow measurement at a lower cost. With the ST50, there is no need for the temperature sensors, flow computers or other devices required with orifice plates, Venturis, Vortex shedding and other meters. The ST50’s design also provides built-in temperature compensation for reliable measurement over a wide temperature range with almost no pressure drop.

Highly suitable for compressed air flow measurement, the ST50 features a wide flow range from 0.23 to 122 NMPS for air, compressed air or nitrogen. Flow meter accuracy is ±1% of reading, ±0.5% of full scale, with repeatability of ±0.5% of reading. The meter operates at temperatures from 4 to 38°C.

The flow meter’s flow range can be field configured in either standard mass flow or volumetric engineering units. It features dual analog outputs, 4-20 mA and 0-10 VDC, which are field assignable as flow rate or temperature, and an RS232C I/O port. A 0-1 kHz pulse output for totalising flow is also available as an option.

The flow meter features a rugged stainless steel sensing element with Hastelloy-C tips. Its electronics are housed in an all-aluminium, epoxy-coated enclosure that is NEMA 4X (IP66) rated and it withstands operational pressures up to 34 bar (g).

The ST50 is available in three field-adjustable U-length probes, 152, 305, and 457 mm to accommodate pipe sizes 51 to 610 mm. Instrument powering options include both 18-36 VDC and 85-265 VAC.
