Key Features
- Measures instantaneous biogas flow rate.
- Can provide cumulative/total gas volume consumed or produced.
- Suitable for monitoring low-pressure biogas systems.
- Available in mechanical or digital configurations depending on model.
- Different pipe connection sizes are available.
- Digital models may provide LCD displays and electronic outputs.
- Advanced models can provide temperature and pressure compensation.
- Some systems can integrate with 4–20 mA, Modbus or other monitoring systems.
- Suitable for biogas containing varying levels of methane, CO₂ and other components, depending on the meter design.
Functions
1. Biogas Consumption Measurement
Measures the quantity of gas used by appliances such as cookers, water heaters, brooders and generators.
2. Biogas Production Monitoring
Helps operators determine how much gas a biodigester is producing over a particular period.
3. Flow-Rate Monitoring
Provides information about the instantaneous rate at which gas is moving through the pipeline.
4. System Performance Monitoring
Changes in measured flow can help technicians investigate problems such as blockages, inadequate gas production or abnormal consumption.
5. Gas Distribution Monitoring
Can be installed at different points in a biogas distribution system to monitor gas supplied to individual sections or equipment.
6. Data Collection
Digital models can provide flow data for monitoring, control and energy-management systems.
Benefits
- Helps users understand how much biogas they produce and consume.
- Supports efficient management of available gas.
- Helps identify unusual changes in gas consumption.
- Provides useful information for maintenance and troubleshooting.
- Helps evaluate biodigester performance.
- Useful for monitoring gas supplied to generators and other high-consumption equipment.
- Can support automated monitoring and remote data collection when equipped with suitable communication outputs.
- Provides continuous or cumulative measurements, depending on the meter.
Applications
The Biogas Flow Meter can be used for:
- Household biodigesters
- Dairy and livestock farms
- Agricultural biogas plants
- Schools and institutions
- Hospitals
- Restaurants and hotels
- Commercial and industrial biogas plants
- Biogas generators
- Biogas cooking systems
- Biogas water heaters
- Biogas poultry brooders
- Biogas gas-storage and distribution systems
Safety
The flow meter should be installed by a suitably qualified technician. Where the installation is in a potentially hazardous atmosphere, the equipment should have the appropriate certification and protection for the applicable installation conditions. Some industrial biogas flow meters are specifically available with hazardous-area approvals.
