Vaisala MGP261 3-in-1 biogas measurement instrument

Vaisala has introduced an in situ 3-in-1 biogas measurement instrument, the Vaisala MGP261, for measuring methane, carbon dioxide and humidity in demanding environments. The compact measurement instrument is Ex certified up to Zone 0, which enables inline installation in explosive atmospheres.

The MGP261 is based on Vaisala’s CARBOCAP infrared gas measurement technology and is optimised for biogas production processes, such as anaerobic digestion of waste from agriculture, industries and municipalities, and the utilisation of landfill gas.

The instrument offers real-time gas composition without sample extraction or treatment. Due to its stable methane measurement, the compact instrument helps biogas plant operators gain comprehensive control over their process and optimise their combined heat and power (CHP) engine performance. The instrument also enables operators to control humidity in order to reduce wear in the CHP engines and process components.

The product is easy to use and install, and it can be fitted to any existing system. The in situ installation of the instrument makes sample treatment unnecessary, enabling measurements without any sampling lines, pumps or moisture removal traps.

The instrument design is resistant to chemicals and the robust metal body is IP66 rated. Furthermore, the operating principles of the instrument mean that no calibration gases are needed in routine operation and Vaisala’s background auto-calibration function reduces expensive calibration work.
