Sage Metering is an innovative manufacturer of the high-performance natural gas flow meter and thermal mass 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 user.

At a single glance, the high contrast graphical display provides flow rate, temperature, total flow, a bar graph, and diagnostic information. The innovative digitally-driven circuit eliminates the traditional drift-prone analog Wheatstone bridge utilized by our competition.

This advancement in circuit design improves stability by eliminating long-term drift and provides for a reproducible zero flow data point.

The reproducible zero flow data flow point enables the user to perform a simple single-point in-situ calibration verification procedure, which verifies that the flow meter continues to operate within the accuracy specifications of the original NIST traceable calibration.

This simple, and unique to Sage Metering procedure, can be performed without interrupting the process and does not require removal of the flow instrument from the pipe or any additional hardware.
