Flow Meter Features ATEX Zone 1 Flameproof Approvals
Sage Metering’s Sage RIO is an ATEX Zone 1 thermal mass flow meter approved for II 2G Ex d IIB+H2 T6 Gb hazardous service for gas flow. The RIO is suitable for heavy industrial and environmental applications and features the Sage In-Situ Field Zero Calibration Check.
RIO features a bright, high-contrast, photo-emissive OLED (organic LED) display of flow rate, total and temperature in an explosion-proof, dual-sided NEMA 4X enclosure. The flow rate is also displayed graphically in a horizontal bar graph format. Powered by 24 VDC (115VAC/230VAC optional), the DC power dissipation is under 2.5 watts. Outputs include 4 – 20 mA proportional to mass flow rate, pulsed outputs of totalized flow and full Modbus-compliant RS485 communications (HART optional).
Sage RIO has a T6 rating suitable for gases with ignition temperatures as low as 85 degrees Celsius (185 degrees Fahrenheit). Insertion styles (for pipes from 1 inch up to 36 inches) or in-line styles (up to 4 inches with flow conditioners) are available (flanges optional). Common applications include flare-gas monitoring, natural-gas measurement in industry (to reduce energy usage, cost accounting or improve combustion efficiency) and landfill and digester gas flow (helps reduce GHG emissions).
