Vaisala MGP262 MGP262 Methane and Carbon Dioxide Multigas Probe

CARBOCAP® MGP262 Multigas Probe for Methane and Carbon Dioxide Measurement is designed for demanding in situ measurement of the offgas in the biogas upgrading process, where low concentrations of methane need to be measured reliably and with high accuracy in the presence of high concentrations of carbon dioxide. The probe belongs to the Vaisala MGP260 series product family.

Stop the loss. The Vaisala CARBOCAP® MGP262 continuously measures the methane concentration in offgas from your biogas upgrading unit to keep you from letting your profits go up in the air. 

Focus on what matters. The MGP262 is the answer to the problem that some methane slip always occurs in the upgrading process. It helps you adjust your process so that you avoid greenhouse gas emissions while you can concentrate on producing the best biomethane possible.

Features:

• Compact in situ probe with low-% CH₄ and high-% CO₂ measurement
• Excellent long-term stability and repeatability with proprietary infrared technology - no calibration gases needed
• Direct installation into process: no sample treatment needed
• Certified for Ex Zone 0/1
• Probe heating eliminates condensation in wet processes
• Corrosion-resistant stainless steel housing (IP66)
• Standalone probe with digital Modbus RTU over RS-485 or 3 analog outputs (4-20 mA)
• Compatible with Vaisala Insight PC software

Direct view to process performance

MGP262 measures the concentrations of the main components in the offgas stream of a biogas upgrading process: methane and carbon dioxide. The methane concentration in the offgas is one of the direct indicators of the process performance. The lower the offgas methane concentration, the lower the methane loss, hence higher yield from the biogas and the smaller the environmental impact. Monitoring offgas composition reliably and accurately enables optimizing the upgrading process as well as determining the amount of greenhouse gases emitted from the process for environmental compliance purposes.

Outstanding methane measurement performance

MGP262 has been optimized for measuring methane concentrations below 5 vol-% with an accuracy of ±0.15 vol-%. Combined with a wide temperature range (-40 to +60 °C), MGP262 is ideal for a wide range of upgrading technologies and processes.

Ease of use

MGP262 is unique in being an in situ probe for demanding explosive environments. No sampling system is needed and there are no moving parts in the probe. Apart from an annual calibration check, MGP262 does not need any consumables or calibration gas cylinders, which makes its maintenance very easy.

Robust, weatherproof, and Excertified for Zones 0 and 1

MGP262 is internationally certified for Zone 0 inside the pipeline and Zone 1 on the outside, allowing installation in any Ex hazardous environment expected in the biogas and natural gas industry. The probe is IP66-rated and specified for ambient temperatures from -40 to +60°C for outdoor installation in harsh environments. Stainless-steel construction, hermetic sealing of optics, and encapsulated electronics provide the probe with maximum robustness and resilience to mechanical shocks, vibration, and corrosive chemicals.
