GE GF868-1-1NEM-21A14 | DigitalFlow Ultrasonic Gas Flow Meter
GE GF868-1-1NEM-21A14 is a high‑precision, clamp‑on ultrasonic gas flow meter from GE Panametrics (DigitalFlow™ series), engineered for non‑invasive measurement of flare gas, vent gas, and process gas in industrial environments. It offers accurate mass/volume flow, velocity, and molecular weight monitoring without pipe cutting or process shutdown.
Key Features
- Non‑invasive Clamp‑on Design: No pipe penetration, no pressure loss, minimal installation cost.
- Dual‑Function Measurement: Measures flow velocity, volumetric flow, mass flow, and real‑time molecular weight.
- Ultra‑Wide Flow Range: 0.03–85 m/s (0.1–275 ft/s) bidirectional; pipe sizes 50–3000 mm (2–120 in).
- No Moving Parts: Resists wear, clogging, and corrosion; zero routine maintenance.
- Harsh Environment Ready: Operating temp -40°C to +70°C; ATEX/IECEx/CE/UL certified.
- Smart I/O & Communication: 4–20 mA inputs/outputs, Modbus, HART, RS232/RS485; 43,000‑point data logging.
- Stable Performance: Immune to gas composition, pressure, and temperature fluctuations.
