Methane measurements

Methane (CH₄) is an odorless and colorless gas, which is produced for example by livestock, landfills and swamps. In the atmosphere, it aggravates the climate change, but in industrial processes, it can be turned into useful products such as heat, electricity or biofuel. Methane is measured in applications such as biogas plants, landfills, and wastewater treatment.

For optimizing raw biogas production and applications with high methane concentrations take a look at the revolutionary in-situ solution CARBOCAP® MGP261 Multigas Probe for Methane, Carbon Dioxide and Humidity.

For optimizing biomethane (RNG) upgrading, minimizing CH4 offgassing and high concentration CO2 measurements in Explosive hazard environments, take a look at our award winning in-situ MGP262 Multigas Probe for Methane and Carbon Dioxide.

Benefits of methane measurement with Vaisala technology

Improved control of biogas quality

By optical methane measurement, you will be able to know the gas quality of your biogas process, and improve the process when needed.

Life-time savings in process control

As the biogas measurement instrument has no moving parts, does not require sampling and needs very little maintenance, you save both time and costs.

Safe in situ measurement

The Ex certification proves that the MGP261 can be installed in situ, meaning directly into the process line. This improves the measurement accuracy significantly.

Vaisala CARBOCAP® MGP261 Multigas Probe for Methane, Carbon Dioxide and Humidity for protecting the Combined Heat and Power (CHP) engine.

What makes our methane measurement unique

Methane is measured in situ without sampling with Vaisala’s patented CARBOCAP® infrared optical measurement technology, which boasts a successful 20-year record of accomplishment in infrared gas measurement. The sensor utilizes the micromachined, electrically tunable Fabry-Perot Interferometer (FPI) filter which enables reliable and stable measurement. Vaisala’s proprietary measurement method eliminates interference from other evaporative hydrocarbons present, preventing cross-sensitivity.
