FCI ST100L thermal mass air/gas flow meter

Tuesday, 10 March, 2015 | Supplied by: AMS Instrumentation & Calibration Pty Ltd



The Model ST100L air/gas inline thermal mass flow meter, from Fluid Components International (FCI), is suitable for chlorine gas service and available with an optional built-in Vortab flow conditioner.

The meter is designed specifically for line sizes of 1″, 1.5″ or 2″ and the flow conditioner overcomes any lack of available straight-run pipe in the installation. The flow conditioner eliminates both swirl and profile disturbances throughout the full flow range, including transitional region, to produce a repeatable flow profile for accurate, repeatable flow measurement.

The meter is typically installed in a water disinfection system’s chlorine gas inlet line to the chlorinator panel. For operation in corrosive chlorine gas environments, the meter’s wetted material - including sensor element, inline flow body, flow conditioner and process connections - is fabricated of Hastelloy C-276 to ensure corrosion protection and long life.

When selecting the flow meter, users have multiple communication options: 4-20 mA analog, frequency/pulse or certified digital bus communications such as HART, Foundation Fieldbus, Profibus PA or Modbus RS485. Should a water plant’s communication need to change, so too can the meter, with field or factory replacement of the output circuit board.

Developed with a graphical, multivariable, backlit LCD display, the meter features a sophisticated readout that continuously displays all process measurements and alarm status for easy on-site viewing by technicians. It also has the ability to query for service diagnostics.

The feature-rich flow meter utilises constant power thermal mass flow sensing technology that measures flow with 100:1 turndown in ranges from 0.01 to 3140 NCMH. The transmitter/electronics can be integrally mounted with the flow body or may be remote mounted to 305 m away. The transmitter enclosure is NEMA4X/IP67 rated and available in painted aluminium or stainless steel.
