Product catalog summary
Product Overview
The Fresenius Off-Gas System, featuring the Gas Dome 300 and GA320, is designed for greenhouse gas monitoring directly at wastewater basins. The system captures and analyzes gases such as N2O, CO2, and CH4, providing real-time emission trends.

Gas Dome 300 + Measurement Principle
The Gas Dome 300 is positioned on the water surface, capturing gas emissions directly at the source. This minimizes ambient air interference. The system measures the volume flow of captured gas, and the GA320 analyzer determines gas concentrations. Emission rates are calculated using the formula: Concentration × Gas Flow ÷ Surface Area.

GA320 + Outdoor System
The GA320 analyzer, housed in a weather-protected outdoor cabinet, integrates gas analysis, flow measurement, and sample gas conditioning. It is configured for N2O, CO2, and CH4, with features like humidity compensation and direct PLC connection, ensuring reliable operation in harsh conditions.

System Overview and Configuration Parameters
  • Target Gases: Nitrous Oxide (N2O), Carbon Dioxide (CO2), Methane (CH4)
  • Measurement Technology: High-precision infrared photometry and specialized gas sensors
  • Gas Dome 300 Material: Corrosion-resistant, lightweight composite
  • Outdoor Cabinet Protection: IP65 weatherproofing with climate control
  • Interfaces/Communication: Direct PLC Connection (Modbus, Profibus, or 4-20mA options)
  • Data Security: Local processing within the GA320, no cloud requirement

Gas Dome 300 + Measurement Principle From the Basin to the Emission Rate Measurement Flow Logic Gas Dome 300 Captured Gas Flow Flow Measurement Volume Flow The Gas Dome 300 is the off-gas hood of the measurement system and is positioned directly on the water surface. A surrounding skirt extends into the water and defines the enclosed capture area. The gas released from this defined surface area is collected and transferred to the measurement system.
