Suitable for Heavy Industrial and Environmental applications and featuring its popular Sage In-Situ ‘Field Zero Calibration Check’, Sage Metering has launched its Sage RIO ATEX Zone 1 Thermal Mass Flow Meter.

The device is approved for EX II 2G Ex d IIB+H2 T6 Gb Hazardous service for Gas Flow and features wide turndown and drift free operation.

High contrast graphical display of flow rate, totalized flow and temperature are also signatures of Sage Metering technology.

The 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. Flow Rate is also displayed graphically in a horizontal bar graph format.

Customer wiring is easy, with separate rear compartment, complete with easy-to-access, well-marked terminals. 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°C (185°F). Insertion Styles (for pipes from 1” up to 36”) or In-Line Styles (up to 4” with Flow Conditioners) are available (flanges optional).

The company explains that common applications of the Sage RIO include flare gas monitoring, natural gas measurement in industry (to reduce energy usage, cost accounting or improve combustion efficiency) and landfill & digester gas flow.
