Product catalog summary
Overview: The FCI ST50 Series Flow Meters are designed for low-cost, low-maintenance measurement of air, compressed air, and nitrogen flow in various industrial applications, including wastewater treatment, HVAC control, and compressed air distribution.
Key Features:
  • Direct mass, volumetric, or velocity flow measurement with dual 4-20 mA analog outputs.
  • Compatible with pipe sizes from 2 to 24 inches (51 mm to 610 mm).
  • Non-clogging sensor with no moving parts and RS232 communications.
  • Optional 4-digit digital display and compact design for easy installation.
Specifications:
  • Flow measurement range: 0.75 SFPS to 400 SFPS (0.23 MPS to 122 MPS).
  • Accuracy: ±2% of reading, ±0.5% of full scale; optional ±1% of reading.
  • Temperature compensation: Standard 40°F to 100°F (4°C to 38°C), optional 0°F to 250°F (-18°C to 121°C).
  • Turndown ratio: 3:1 to 100:1.
Installation and Configuration:
  • Available in three standard configurations with adjustable insertion lengths.
  • Enclosure features dual conduit ports and is rated NEMA 4X (IP66/IP67) for durability.
  • Power options include DC (18 V to 36 V) or AC (85 V to 265 V).
Calibration and Testing:
  • Calibrated in FCI's flow laboratory with equipment traceable to NIST and ISO/IEC 17025 standards.
  • Custom calibration available for specific applications, subject to validation.
Materials and Construction:
  • 316 stainless steel body with Hastelloy-C22 sensor tips for durability.
  • Optional ball valves available for different pressure and temperature ratings.
Applications: Suitable for industrial environments requiring accurate and maintenance-free flow measurement solutions, such as process improvement and replacement of high-maintenance meters.
