Next Generation Fixed Gas Analyser From QED Environmental Systems

Building on field-proven gas analysis technology, the compact self-contained BIOGAS 3000 system offers cost-effective online monitoring that is ideal for anaerobic digestion, biogas monitoring, and landfill gas monitoring applications.

The BIOGAS 3000 can be configured for up to four sampling points to monitor methane (CH4), carbon dioxide (CO2), and oxygen (O2), with optional monitoring of hydrogen sulphide (H2S), hydrogen (H2) and carbon monoxide (CO) levels – operators can choose up to five gases to monitor.

The unit is also available with a continuous monitoring option for CH4, CO2 and O2. By incorporating external H2S sensors in ranges from 50 to 40,000 parts per million (ppm), it can be manufactured to monitor before and after desulphurization. Pre-calibrated sensors are also available, which can limit system downtime.

The BIOGAS 3000 features easy self-installation and maintenance. In addition, QED provides a temporary replacement analyser module, resulting in zero operational downtime for servicing. The BIOGAS 3000 offers simple user calibration and an easy-to-operate system. It is calibrated to ISO/IEC 17025 standards for optimum accuracy.

Operators can also choose between a built-in liquid level monitoring feature equipped with a dedicated alarm and manual turn moisture removal drain, or chose an automatic drain option that empties the catchpot without manual intervention, offering flexibility for on-site maintenance.

Built with an IP65-rated enclosure, the BIOGAS 3000 is certified for use in potentially explosive atmospheres (CSA), (ATEX) and IECEx (IEC System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres) Zone 2 areas. A variety of options are available for communication with a SCADA system, including six configurable 4-20mA outputs with a Modbus RTU communication protocol. Process Field Bus (PROFIBUS) and Process Field Net (PROFINET) and Ethernet (Modbus TCP/IP) communication protocols are also offered.
