Fluid Components Intl. (FCI) Insertion Mass Flow Meters ST51

Description
The Model ST51 and ST51A are a compact, low cost solution for accurate, repeatable flow measurement of biogas, digester gas, landfill gas, methane and natural gas as well as air, compressed air or nitrogen. This insertion-style flow meter has no moving parts and is available in probe lengths for installation into pipe diameters from 2.5 inches to 24 inches [63 mm to 610 mm]. It is easily connected into the pipe via a 1/2 inch or 3/4 inch NPT compression fitting. ST51 uses constant power thermal dispersion drive technology, with a slightly heated sensor, which uniquely provides a subtle drying effect on the sensors that results in effective measurement in moist gas applications. The ST51 Series electronics are housed in rugged, IP67 rated enclosure with dual conduit ports in either NPT or M20 threading. The instrument comes standard with dual 4-20 mA, NAMUR NE43 complaint outputs and a 500 Hz pulse output. The model ST51A adds HART or Modbus, a higher process temperature service range, a SIL compliance rating and extended warranty. The transmitter/electron ics can be integrally mounted with the flow element (probe) or be remote mounted to best match your installation situation. The complete instrument carries global Ex agency approvals for Division l/Zone 1 installations. The ST51 flow sensing element features precision, platinum RTD in small diameter, "equal-mass," all-metal thermowells to provide superior accuracy, repeatability and fast response. Applications Landfill gas recovery (LMG) Wastewater treatment plant digester Coal mine methane recovery Air/compressed air with totalized flow Livestock and dairy farm on-farm biogas recovery Biogas: biomass fermentation and recovery Biomass gasification
