Increasing Process Efficiency, Conserving Energy, & Improving the Environment One Meter at a Time

Sage Metering is a manufacturer of high performance Thermal Mass Flow Meters which measure the flow rate and consumption of gases for multiple industrial and commercial applications. Frequently used for energy management systems to monitor and improve energy efficiency as well as for regulatory compliance in environmental systems including reporting of Greenhouse Gas Emissions.

Typical Applications include measurement and sub-metering of natural gas and compressed air for energy utilization and cost accounting within a facility. Measurement of combustion air flow can be used for improving efficiency in boilers and furnaces. Environmental reporting of Greenhouse Gases from combustion sources as well as measurement for carbon credits are frequently encountered.

Sage Prime HVAC Thermal Mass Flow Meter

The Sage Prime HVAC thermal mass flow meter measures natural gas flow rate and consumption in commercial, municipal, and industrial buildings, as well as school campuses, government facilities, hospitals, shopping centers and office buildings and complexes.

The Sage flow meters are ideal for submetering gas usage for billing or zone balancing, provide data to help reduce energy costs, for cost accounting and to aide combustion efficiency strategies for the boilers that produce steam for heating.
