Flare Gas Flow Meters
Flare gas flow meters are essential instruments used in upstream, midstream, and downstream oil and gas operations to accurately measure the flow of combustible and non-combustible gases being released through flare systems. These meters play a critical role in environmental compliance, emissions monitoring, process optimisation, and ensuring operational safety, particularly during upset conditions such as emergency blowdowns.
The challenge of flare gas measurement lies in the highly variable flow rates, fluctuating gas compositions, and often extreme process conditions. Conventional flow meters struggle to maintain accuracy under these conditions. Ultrasonic flare gas meters have become the preferred solution, offering non-intrusive, high-velocity measurement without pressure drop. They are particularly suited to low-pressure systems, intermittent flows, and applications where maintenance access is limited.
As regulatory bodies place increased scrutiny on methane emissions and flare activity, especially with the introduction of the EU Methane Regulation (legislated in May 2024) the need for accurate, traceable, and auditable flare flow data has become paramount. Operators are now expected to meet the highest standards in monitoring, reporting, and verification (MRV) of emissions, and to reduce methane emissions through better measurement and control of flaring.
Advanced flare gas flow meters go beyond simple velocity measurement. They typically include integrated flow computers capable of calculating mass flow, density, compressibility, molecular weight, and other key parameters. Some systems include redundancy features to ensure data integrity even during signal loss or probe contamination, and others offer software tools for real-time flow correction, incident logging, and historical data storage.
ABLE Instruments offer the ABLE FlareMaster FT Ultrasonic Flare Gas Metering System, a state-of-the-art ultrasonic flare gas metering system that integrates advanced flow correction algorithms, real-time measurement verification, automated error handling, and industry-standard gas property calculations (AGA10/API). Designed with environmental compliance in mind, it also features embedded nitrogen subtraction capabilities to support accurate mass flow and emissions reporting in accordance with fiscal and regulatory demands.
If your facility is seeking a dependable, regulatory-compliant flare gas flow meter with robust performance under the most demanding conditions, the ABLE FlareMaster FT offers an innovative, proven solution.
