Natural Gas Submetering Thermal Flow Meters Ideal for Plant or Process Fuel Usage Tracking and Emissions Monitoring
The FCI family of thermal flow meters are economical and easy-to-install, versatile solutions to measure the flow rate and totalized flow of air and natural gas. They are direct mass flow measuring, wide range 100:1 turndown instruments, all with precision calibration in natural gas flowing at actual installation temperature and pressure conditions.
FCI’s inline or insertion designs provide a threaded or flanged connection into the piping from 0.25 inch [DN6] to the largest of line sizes, powering by AC or DC sources, and large choice of local digital readouts, analog, and digital bus outputs, explains the firm.
The compact flow meters are ideal for insertion or inline natural gas line sub-metering tasks. Like all FCI thermal meters, they provide Div2/Zone2 compliant, direct mass flow measurement requiring no pressure, temperature, or other components. Independently evaluated SIL 2 certification as an HFT0 device makes them the choice for safety instrumented system (SIS) critical processes, states the company.
ST51, ST51A Series
These flow meters are designed as a low cost, compact yet rugged, Div1/Zone1 rated solution for accurate, repeatable flow measurement of natural gas, bio-methane, and air. This insertion-style flow meter is available in probe lengths for installation into pipe diameters from 2.5 to 24 inches (63 to 610 mm). Connection is via a 0.5 or 0.75 inch (12.7 to 19.05 mm) NPT compression fitting. Dual 4-20mA outputs are standard with HART or Modbus I/O optional.
ST75, ST75A Series
These flow meters provide a low cost, compact, yet rugged solution for accurate, repeatable direct mass flow measurement, mentions the firm. These in-line (spool-piece) style meters have no moving parts and are for use in pipe diameters from 0.25 to 2 inches (6 to 51 mm). They feature wide 100:1 turndowns and come standard with dual 4-20 mA outputs and a 500 Hz pulse output. Optional are HART or Modbus I/O communication and integrated Vortab flow conditioners.
ST80, ST80L Series
These flow meters offer a high performance, rugged instrument with ultra-reliable, feature-rich electronics, and the firm’s fast response time, Adaptive Sensing Technology (AST). They feature the industry's most extensive selection of application-matched flow sensors, including the company’s new ‘wet gas’ flow element, a broad choice of process connections, and industry’s widest selection of outputs to provide a truly superior solution for industrial processes and plant applications, explains the company.
These flow meters are claimed to be the industry’s most advanced thermal gas instrument. They include feature-and-function-rich electronics and sensors, ultra-rugged IP67, Div1/Zone1 transmitters, and superior 0.75 % of reading accuracy. Whether the output is 4-20 mA analog, frequency/pulse, or digital bus communications such as HART, Foundation Fieldbus, PROFIBUS, or Modbus, the ST100A has it covered, concludes the firm.
