Evolving Measurement Demands in the Global Biogas and Biomethane Industry
Global biogas and biomethane production are expanding rapidly, shifting industry priorities from project deployment to efficient operation, accountability, and long-term reliability.
Europe remains one of the most advanced regions in the biomethane sector, operating more than 1,600 production plants with a combined annual capacity of approximately 7 billion m³. The region has also established a mature regulatory and certification frameworks, such as EN 16723-1 and MARCOGAZ-GIE guidelines, that emphasize measurement integrity and grid-injection reliability.
Similar trends are unfolding globally. In North America, low-carbon fuel standards and clean-fuel credit systems are reinforcing the need for verifiable flow and energy data. Across Asia, waste-to-energy and agricultural sustainability programs are accelerating investment in biogas utilization and upgrading.
As production capacity increases and project scales diversify, the industry’s focus has moved beyond deployment to ensuring continuous operational efficiency and measurement consistency. These evolving demands highlight the need for precision flow-monitoring technologies capable of delivering reliable data under real biogas conditions.
Measurement Challenges in Biogas and Biomethane Applications
However, accurate flow measurement in biogas and biomethane systems involves a set of complex technical and environmental challenges.
Gas composition varies significantly with feedstock type, digestion process, and operational conditions, leading to fluctuations in methane concentration that directly influence gas density and flow velocity. In addition, condensation, suspended moisture, and particulate impurities often occur within pipelines, creating signal interference and corrosion risks that shorten measurement equipment lifetime.
Temperature and pressure changes in decentralized biogas plants introduce further uncertainty in flow readings, while irregular flow field distribution within large ducts reduces measurement stability. Conventional mechanical or thermal flow meters frequently experience accuracy degradation or signal drift under these conditions, resulting in unreliable long-term performance.
A stable, corrosion-resistant, and maintenance-free flow measurement technology capable of providing consistent precision under wet and composition-variable gas conditions has therefore become essential for modern biogas and biomethane operations.

To meet the demanding requirements of biogas and biomethane measurement, Cubic Instruments, a leading manufacturer of gas sensors and gas analyzers, applies extensive expertise in gas composition and flow measurement to the field of biogas and biomethane metering.
By addressing the specific challenges of wet, corrosive, and composition-variable gas environments, Cubic Instruments provides advanced ultrasonic flow monitoring solutions, BF-3000 and BF-3000B Biogas Flow Meters, that ensure measurement accuracy, operational stability, and long-term reliability across diverse renewable gas applications.
• Ultrasonic Biogas Flow Meter BF-3000: In-Line Flow and Methane Monitoring for Biogas and Biomethane Applications
Utilizing advanced ultrasonic time-of-flight (TOF) technology, Cubic Instruments BF-3000 Biogas Flow Meter is developed for simultaneous and high-precision measurement of flow rate and methane concentration, enabling continuous monitoring of biogas quantity and quality for precise process control and energy accounting.
To ensure higher measurement accuracy under varying process conditions, BF-3000 incorporates built-in temperature and pressure sensors that provide real-time compensation during operation. Stable long-term performance is further supported by a ceramic-coated probe, which resists corrosion and maintains reliable ultrasonic transmission in humid and chemically aggressive biogas environments.
With no moving parts, BF-3000 eliminates mechanical wear and minimizes maintenance requirements, while its non-intrusive design ensures limited pressure loss in practical operating conditions.
For decentralized or off-grid sites, the built-in industrial lithium battery in BF-3000 provides backup power for continuous monitoring in cases of unstable external power supply, ensuring uninterrupted data acquisition for long-term performance tracking.
Delivering accurate, stable, and long-term flow measurement, BF-3000 provides a dependable solution for biogas and biomethane production, upgrading, and grid-injection applications, helping operators achieve higher process efficiency, improved energy utilization, and consistent gas-quality assurance.
• Ultrasonic Biogas Flow Meter BF-3000B: Bypass Flow Measurement for Enhanced Stability and Durability
BF-3000 serves applications where compact, direct in-line installation is preferred, while BF-3000B extends the same ultrasonic precision to environments requiring higher isolation and corrosion protection.
Developed for challenging biogas conditions, BF-3000B combines ultrasonic transit-time differential and pressure differential measurement principles to ensure stable and precise flow monitoring even when gas composition fluctuates.
The bypass configuration allows BF-3000B to infer the flow of the main pipeline by accurately measuring the gas flow through a small bypass channel, which effectively minimizes disturbances caused by irregular flow fields and high CO2 concentrations.
Beyond measurement performance, the bypass structure provides comprehensive durability advantages. The isolated design prevents condensate accumulation and shields internal components from corrosive exposure, while the stainless-steel body ensures mechanical durability under harsh operating conditions. The modular configuration enables quick installation and maintenance without interrupting main pipeline operation, supporting long-term measurement accuracy and operational reliability in humid or corrosive biogas environments.
Similar to BF-3000, BF-3000B is also equipped with an industrial lithium battery that provides backup power for continuous data acquisition, ensuring uninterrupted operation even at decentralized or remote biogas sites.
Purpose-built for demanding raw biogas applications, BF-3000B integrates Cubic Instruments’ advanced ultrasonic sensing technology with reinforced durability to ensure stable performance under real-world conditions.
BF-3000B extends the same technical principles as BF-3000, demonstrating Cubic Instruments’ capability to design flexible and robust flow-metering solutions across the renewable-gas value chain.
