Natural Gas Meters

Natural gas submetering provides visibility into one of the largest — and least monitored — energy costs in commercial and industrial facilities. While utility meters track total building consumption, submeters reveal how gas is distributed across boilers, rooftop units, kitchen equipment, labs, and process loads.

Emergent Metering offers the Sage Model 51 thermal mass flow meter, which measures natural gas flow directly in mass units without requiring separate pressure and temperature transmitters. This direct mass measurement approach simplifies installation and improves accuracy compared to volumetric meters that require pressure and temperature compensation.

The thermal mass principle provides a 100:1 turndown ratio, accurately capturing both peak demand and low-flow periods that rotary and diaphragm meters miss. BACnet and Modbus outputs enable direct integration with building automation systems and energy management platforms. Common applications include boiler plant monitoring, rooftop unit gas consumption, laboratory exhaust makeup air units, and kitchen equipment submetering for multi-tenant allocation.
