Sage Prime Thermal Mass Flow Meter

In this video Bob Steinberg, Sage Metering President, shows the extreme low-end sensitivity and rangeability of the flowmeter which is used in a variety of applications, to measure gas mass flow.

More Information on the Sage Prime

The Sage Prime is often used to measure gas mass flow rate and consumption in a wide range of applications, such as monitoring compressed air or natural gas flow for energy management, or to sub-meter gas for cost allocation. Sage meters are also used to monitor digester gas or biogas for carbon credits to help reduce greenhouse gas emissions. Other applications include vent air, combustion air, and flare gas.

Sage Metering is a pioneer in technology development, having brought the first hybrid-digital bridge circuit to the industry over ten years ago. This provided a quantum leap in flow meter performance and long-term reproducibility. Sage also introduced the high contrast, easy-to-read graphical display of the Sage Prime, with its compact design, low power dissipation, high resolution and wide rangeability.

Perhaps the company’s most significant contribution to the industry was the introduction of the In-Situ Calibration Check over five years ago, which eliminates the cost and hassle of periodic factory recalibrations. All Sage meters feature this calibration validation method, which is a simple, three minute check at a “no flow” condition. The on-site test is reliable, regardless of the test gas temperature, and assures that the sensor is clean, and the flow meter has not drifted, shifted or changed since its initial NIST traceable factory calibration.

One of the most notable features of the Sage Prime (in fact, all of the Sage flow meters) is the extreme sensitivity. This is due to the proprietary circuit that has a resolution of up to 1000 to 1, and one second response time. In contrast, other thermal mass flow meter manufacturers have a response time of at least 15 seconds and require a low-end flow limit or cutoff.
