FCI ST100 Thermal Flow Meter

The ST100 Series Thermal Flow Meter from Fluid Components International (FCI) provides precision mass flow measurement and is suitable for instrument and plant engineers responsible for managing processes with a wide range of hydrogen gas applications.

The flow meter can be calibrated to measure H₂ or virtually any process gas, including wet, mixed and dirty gases. The basic insertion-style air/gas meter features a thermal flow sensing element that measures flow from 0.07 to 305 NMPS with accuracy of ±0.75% of reading, ±0.5% of full scale. H₂ also can be measured safely at high flow rates from 0 to 3000 kg/h at 200 to 600 kPa.

Its no-moving-parts design also virtually eliminates wear, breakage and maintenance. Uses can choose from various communication options including 4–20 mA analog, frequency/pulse or certified digital bus communications such as HART, Foundation Fieldbus, Profibus PA or Modbus RS485.

The device includes a graphical, multivariable backlit LCD display, which continuously displays all process measurements and alarm status for easy on-site viewing by technicians; and a user-selectable and programmable data logger, with readings stored in a removable, internal 2 GB micro-SD card.

The product is also certified to FM, FMc, ATEX, IECEx, EAC/TRCU, CPA, NEPSI and InMetro, and is CE approved.
