Sage Thermal Mass Flowmeter

Sage Metering is an innovative manufacturer of high-performance natural gas flow meters for gas flow measurement. The company has brought to market the first thermal mass flow meter to utilize graphical displays, a hybrid digitally driven circuit, and the industry’s first in-situ calibration verification system.

These state-of-the-art, award-winning features deliver the highest performance, reliability, and confidence for any thermal flow meter. At a single glance, the high contrast graphical display provides flow rate, temperature, total flow, a bar graph, and diagnostic information.
