The Sage Model 51 is a precision thermal mass flow meter engineered for accurate measurement of natural gas, biogas, compressed air, and other industrial gases. NIST-traceable calibration and proven thermal dispersion technology make it an ideal solution for utility billing, emissions monitoring, combustion control, and process flow applications where reliable mass flow data is critical.
Measuring true mass flow directly—without the need for separate temperature and pressure correction—the Sage Model 51 delivers excellent low-flow sensitivity, wide turndown, and minimal pressure drop. Its rugged construction, insertion or inline configurations, and clear digital display make installation and ongoing monitoring straightforward across pipes and ducts of many sizes.
