Key Features to Consider When Choosing a Biogas Flow Meter
When selecting your biogas flow meter, consider these crucial factors:
Measurement Accuracy and Repeatability
Your flow meter's accuracy directly impacts your operation's efficiency. Look for meters offering at least ±2% accuracy for basic applications, though some modern sensors can achieve ±0.25% accuracy.
Operating Ranges
Consider:
Pressure ranges (typically 0-10 bar)
Temperature ranges (-20°C to +60°C)
Flow ranges (specific to your application)
Communication and Data Logging
Modern biogas analysis equipment should offer:
Digital communication protocols (HART, Modbus, etc.)
Remote monitoring capabilities
Data logging systems
Integration with existing SCADA systems You can put any text here
06 Installation and Maintenance Best Practices
