what is biogas

What is biogas?

Biogas is a fuel consisting mainly of methane.

The biogas production process involves the fermentation of organic matter from plants and animals, biological waste and effluents from the food industry.

Methanization is caused by anaerobic fermentation (complete absence of oxygen) in digesters used to treat wastewater, landfill or agricultural waste products.

Once purified,Biomethane can be transformed into green, renewable energy.

This gas can be used to produce energy in the form of heat or electricity.

Why measure biogas flow with a biogas meter?

Optimizing the biogas fermentation process requires data on the process and the quantity produced.

Accurate and reliable measurement of biogas flow rate and composition is recommended to monitor the fermentation process and guarantee quality.

Thanks to the flowmeter's information, actions can be taken to improve energy production and recovery.

how to measure biogas flow

How to measure the biogas flow rate?

The prerequisite for reliable, accurate and reproducible flow metering is the determination of flow under standard conditions.

The Fuji Electric biogas flowmeter consists of :

These flow meters enable volumetric flow to be corrected to standardized pressure and temperature.

For flow calculation under normal reference conditions (0° C, 1.01325 bar), the COF CH4 multichannel flow computer enables acquisition and display of 1 to 6 counting channels.

An optional ZSPB gas analyzer can be combined to measure methane content and carbon dioxide CO2, O2 and H₂S levels on the methanizer.

biogas flow meter applications

What are the applications of biogas flow meters?

Fuji Electric flow meters are low-pressure meters designed to monitor :

  • biogas from landfills sites (collected, recovered, flared)
  • waste gas from anaerobic digestion and agricultural anaerobic digestion
  • Pumped-storage gas (PST)
  • gas engines.
  • .

Flowmeter operation is perfectly suited to determining the characteristics of biogas containing high CO2 or other substances in lower quantities such as H₂S.

the challenges of biogas measurement

What are the difficulties involved in measuring biogas flow?

Unlike natural gas or compressed air, biogas is a moist, corrosive gas, so longevity and long-term measurement stability are particularly important considerations.

The raw materials used, the types of waste and the conditions under which they are processed all lead to varying digestate quality and hence to different gas composition.

Fluctuations caused by batch operation (solid waste treatment/composting plant) or aging landfill sites bring another challenge: the accuracy of measurement readings can deteriorate if the concentration of CH4 methane volume varies.

It is therefore essential for the flowmeter to be pressure and temperature compensated, if the accuracy and quality of the manufacturing process are to be guaranteed.

What are the advantages of the Fuji Electric biogas flow meter?

The biogas meter is approved for transactional metering thanks to its technical features.

Fuji Electric's biogas meter technology has no moving parts, guaranteeing long life and low maintenance.

The flow meter is easy to dismantle and clean. It is suitable for use with low or high methane content.

The flow sensor installed on the stainless steel line is highly resistant to chemical attack compared with other technologies (flanged Vortex flow meter, ultrasonic flow meter, insertion thermal mass flow meter, flanged turbine flow meter). The aluminum sensor body guarantees long service life.

The Fuji Electric biogas meter guarantees simple operation for measuring consumption on a biogas line.

These flow meters offer the best quality-price-performance-safety ratio on the market.

How do you maintain biogas flow meters?

To ensure impeccable precision in measurement, it's crucial that the instruments used not only comply with rigorous European standards, but also undergo regular checks. In France, measuring equipment must meet two fundamental requirements: homologation via a CE approval certificate or recognized model validation, and scrupulous compliance with the regulatory metrological control schedule.

Prior to commissioning, it is essential that meters are accurately calibrated with a gas of similar quality to the one they will be measuring. This process guarantees their accuracy and reliability right from their first use.

Another pillar of metrological compliance is the maintenance contract. This must include at least one annual visit for each meter, a practice that helps maintain performance and prevent any anomalies.

Finally, compliance with the manufacturer's recommended metrological inspection intervals is another important criterion. These periodic checks are crucial to maintaining measurement accuracy over time.

By following these guidelines, you can ensure the reliability and accuracy of your measurements.
