A Flonidan smart gas meter (G4, GALLUS LNE-11827 2011, Denmark) was used to measure biogas volume by releasing the produced biogas through a pipe connected to the instrument until the pressure in the digester headspace was reduced to the ambient atmospheric pressure.
In agricultural areas anaerobic digesters are used for generating biogas using grass and vegetation such as tomato plant stems and other similar residues; the gas is burnt to provide electricity.

The digester is used by mixing cow dung with water into a slurry which is then added to the digester through an inlet pipe.
Hub and pods will make high-yielding liquid biomass available to on-farm anaerobic digester plants, allowing the economic and environmental benefits to be enjoyed at a local level, as well as recycling nutrients back onto the land.
The 1,100 cu m digester currently handles 11,000 tonnes of slurry each year, generating up to 160kW electricity - roughly double that of a conventional AD plant.
