Sage Metering Thermal Mass Flow MetersSage Paramount Industrial Thermal Mass Flow Meter

Sage Paramount TM is Sage Metering's next-generation industrial thermal mass flow meter with a NEMA 4X enclosure (safeguards against harsh environmental elements and corrosion) and permits the user to reconfigure the meter in the field while using the SageCom software.

Sage Prime ® is Sage's flagship model, used by industrial, environmental, or commercial end-users. It is housed in a dual-sided NEMA 4 enclosure, with full Modbus® compliant communications and is UL, CSA, and ATEX compliant.

Sage Rio TM is an industrial thermal flow meter with Class I Division 1 Groups B, C, D, and ATEX Zone 1 Flameproof approval, ideal for flare gas monitoring, landfill gas flow, digester gas flow measurement, and natural gas measurement.

Sage 300 ™ is the low-cost thermal mass flow meter option offering comparable performance as the Prime, with fewer premium features.

Flow Meter Applications


A thermal mass flow meter may help in a variety of environmental applications, such as anaerobic digestion wastewater treatment, atmospheric storage tank vents, biogas measurement, carbon credit trading, flare gas measurement, flue gas monitoring, ethanol production, greenhouse gas reporting, landfill gas monitoring, manure or methane digestion, wastewater aeration, and wastewater treatment odor control.

Thermal mass flow meters excel in monitoring greenhouse gases in various applications, including biogas, landfill gas, and flare gas flow measurement.  Read More >

Reduce Energy Costs

Thermal mass flowmeters increase productivity, reduce energy costs, and maximize product yields. They save operators money in many applications, including natural gas measurement, facilities management, and energy management, compressed air flow Measurement, LEED building and natural gas submetering, and aeration flow.

Industrial plants are saving energy using energy management and compressed air monitoring systems which cut cost and improve efficiency and performance.  Read More >


The Sage gas meter delivers the highest performance, reliability in a variety of industrial applications, such as combustion control, compressed air measurement, gas valve testing, greenhouse gas emissions reporting, natural gas flow measurement, nitrogen monitoring, performance contracting, submetering natural gas, textile manufacturing, and vent air flow measurement.

Thermal mass flow meters are an effective way to measure flare gas when the gas composition is known and is offering a viable solution to the high expense of ultrasonic meters.  Read More >

Submetering Natural Gas-Industrial

Because of the rising energy costs, along with societal and government pressure to reduce emissions, monitoring natural gas mass flow and consumption within a facility's zones, have become desirable. By observing a facility's gas flow, it encourages not only conservation but also assesses process efficiencies, identifies the occurrence of unexpected flow, and can cost allocate various operating areas. Additionally, by submetering process equipment, fuel leaks can be detected, and information from the flow meter may determine if the devices need maintenance or replacement.

Natural Gas - Commercial and Residential

Government regulations often require submetering of natural gas at campuses, large residential projects, high rise buildings, government facilities, large commercial applications, or shopping centers. Even when it's not required, energy-minded stakeholders and landlords often use submetering. By monitoring the flow rate and consumption at individual zones, it becomes possible to identify abnormal consumption points, encourage conservation, reduce energy costs as well as minimize environmental impact.
