The Sage 300 thermal mass flow meter is an economical alternative to the Sage Prime® while offering comparable performance. The meter measures gas mass flow and has the same accuracy, repeatability, low-end sensitivity, response time, turndown and resolution as the Prime without some premium features.

If the user needs to verify that the meter is in calibration, while still in the field and in the pipe, use the Sage Prime, which includes the award-winning Sage In-Situ Calibration Verification. Likewise, if a high-contrast graphical display is desired, the Prime will better serve your needs.
