The Fuji Electric biogas flow meter has been developed and certified specifically for the biogas market, using Pitot tube and pressure transmitter differential flow measurement technology. This transactional flow meter directly determines gas flow at a standardized pressure and temperature.
The Fuji Electric biogas flowmeter provides instantaneous and totalized measurements of biogas flow rate to determine the quantity and quality produced.
These measuring devices enable quantities of recovered gas to be measured by direct measurement in application ofarticle 4 of the order of December 28, 2017.
These approved meters are MID MI-002 / CET biogas certified.
They comply with the provisions of Decree no. 2001-387 of May 3, 2001, as amended, on the inspection of measuring instruments to qualify for the reduced rate of the general tax on polluting activities (TGAP). These measuring instruments must conform to an approved model or an EC model approval certificate.
Biogas is a fuel made up 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.
Biomethane can be transformed into green, renewable energy once it has been purified.
This gas can be used to produce energy in the form of heat or electricity.
Optimizing the biogas fermentation process requires data on the process and the quantity produced.
Accurate, reliable measurement of biogas flow 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.
The prerequisite for reliable, accurate and reproducible flow metering is the determination of flow under standard conditions.
The principle of the Fuji Electric biogas flowmeter consists of :
These flowmeters enable volumetric flow to be corrected to standard pressure and temperature.
For flow calculation under normal reference conditions (0° C, 1.01325 bar), the COF CH4 multi-channel flow computer enables acquisition and display of 1 to 6 counting channels.
An optional ZSPB gasanalyser can be combined to measure methane content and carbon dioxide CO2, O2 and H₂S levels on the methanizer.
Fuji Electric flow meters are low-pressure meters designed to monitor :
Flowmeter operation is perfectly suited to determining the characteristics of biogas containing high CO2 or other substances in lower quantities such as H₂S.
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 mean that the quality of the digestate varies, and therefore the composition of the gas.
Fluctuations caused by batch operation (solid waste treatment/composting plant) or aging landfills 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.
The biogas meter is approved for transactional metering thanks to its technical features.
Fuji Electric's biogas meter technology has no moving parts, ensuring 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 flowmeter, ultrasonic flowmeter, insertion thermal mass flowmeter, flanged turbine flowmeter). The aluminum sensor body guarantees long service life.
The Fuji Electric biogas meter guarantees simple operation for measuring consumption on a biogas line.
Sensors and probes ensure plant safety thanks to their hazardous area approvals.
These flowmeters offer the best price-performance-safety ratio on the market.
To ensure impeccable precision in the field of measurement, it is 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.
Before commissioning, it is essential that the 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 equipment 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.
