Continuous Monitoring




Biogas Systems are the proud to be associated with AmbiSense Ltd as a distributor and service support provider across Australasia for their GasfluxTM  continuous monitoring device. GasfluxTM  is the world’s first continuous gas and flow monitoring device (patent pending) for LFG and ground gas applications. The technology enables real-time monitoring of landfills, brownfield sites, onshore O&G facilities and industrial sites, for a range of applications and desired outcomes.


Continuous monitoring is an excellent way to quickly build up an accurate representation of LFG and ground gas behaviour on contaminated land and landfill sites, coal and other O&G facilities, and for carbon sequestration projects. Monitoring of gas concentrations alone does not always provide a complete picture, and relying on spot flow-measurements often leads to sites being characterised in an overly conservative manner, adding unnecessary costs in terms of potential gas mitigation measures.


GasfluxTM  is a platform technology providing continuous monitoring of gas and air, and reporting the data via telemetry systems to be stored on a cloud network. The comprehensive data set can then be used in a wide range of applications in order to provide valuable insights to LFG and ground gas behaviour.


The GasfluxTM  units can be installed on a range of pipe diameters and in a range of applications, not just monitoring bores. This provides greater flexibility for LFG and ground gas monitoring with a wider range of deployment. The GasfluxTM  units can also be used in LFG collection system optimisation, as they can be used for large pipe diameter deployment and an array.


The GasfluxTM  software interface includes the following:

  • Secure customer login
