Product Overview
This natural gas and air thermal mass flow meter is engineered for accurate combustion fuel measurement in boilers and heaters. Using direct mass‑flow thermal dispersion, it eliminates the need for external pressure or temperature compensation. Its hot‑tap insertion design allows easy installation and retrofits without shutdown, while delivering ±1% FS accuracy, ±0.2% repeatability, and 200 ms response time. Certified for EPA GHG reporting and Boiler MACT compliance, it’s ideal for monitoring methane, propane, or natural gas consumption. Standard features include pulse output, alarms, totalizer, diagnostics, LCD display, and Modbus capability. With no moving parts and negligible pressure drop, it provides long‑term reliability in demanding combustion environments.
