MWA provides a number of products designed to work with “dirty gas” – gas that is either polluted or wet – such as biogas, landfill gas and digester gas. This type of gas needs special equipment that can consistently handle the unpredictability of flow and composition that arises from these scenarios.
When it comes to managing and monitoring gas, it is essential to have a reliable and accurate metering system. MWA is on hand to provide with a range of equipment and expertise that can assist in tackling applications that handle dirty gas.
Meters designed for polluted applications
MWA proudly offers the GD 300 and GD 500, meters which are designed to handle gas from polluted sources, such as landfill gases, biogas digesters and more. The GD 300 and 500 have an incredible wide range of applications, and being designed to work in these challenging environments, they are resistance to dirt such as oil, rust and sulphur. In addition, the installation of a GD series is simple and doesn’t require recalibration.
Typical gas types for the GD series:
- Biogas
- Landfill gas
- Digester gas
- Sewage gas
- Industrial gas
- Medical gas
If you are working with any of the gases above, don’t hesitate to contact MWA about the GD 300 and 500 series, and learn more about how it can work in your application.
Expand your functionality with external flow computers
The GD 300 and 500 series can be further enhanced with the installation of external flow meters from Esters. This allows for all data to be logged and recorded automatically, with data visualisations and daily status reports sent via email. Consult with the experts at MWA about the best flow meter for your dirty gas solution, as we will ensure you are left with a solution that gives you full control.
Incredible accuracy even in highly polluted mixes
The GD 300 and 500 are designed for polluted mixes and can measure within 1.5% accuracy even in highly polluted mixes, including both extremely corrosive and inert gases. Integrated condensate discharge means the meter can be integrated into gas lines with even a 100% damp biogas mixture, and still delivers incredibly accurate results.
