Description

The SWG100 BIOGAS is a biogas analyser which provide continuous monitor of 02%, CO2%, CH4%, H2S, H2 and CO gases primarily in Biogas generated from large and medium AD (Anaerobic digestion) and Biomethane plants.

Choosing the correct Biogas Analyser.
Eurotron Instruments offers 2 additional models of BioGas Analysers:

• If your application involves installations in WWTP ( Waste Water Treatment Plants) or Landfil sites, the SWG100 BIOEX, ATEX ZONE II certified gas analyser will be a better solution. Please click this link
  
• If your application involves installations for small size farm based anaerobic digesters and you only require 1-2 sampling points and not a continuous monitor system then please visit the SGW100 BIOCOMPACT page .

Continuous monitor system.
The SWG100 BIOGS analyser continuously measure O2, CO2%, CH4% and H2S which means that it detect gas changes as they happen. In some processes, the quality of the biogas changes quickly and CHP’s Gas Engines require a live signal to adjust to these changes.

Built-in Gas Cooler.
The SWG100 BIOGAS integrated gas cooler, along with the peristaltic pump and the AUTO CAL functions provide high accuracy, repeatable and stable readings in any process conditions even with extreme wet gases, such has biogas sampling before the heating treatment. The employment of the gas cooler also maximise sensors protection from moisture build-up in the gas stream.

H2S Innovative Dilution system 50:1 

The optional dilution system installed on the H2S channel is proven to be essential in many applications where H2S can fluctuate from very low ppm to very high concentration. This innovative system allow to continuously measure H2S in any process condition whilst protecting the sensor from sudden rise of H2S levels. Typical applications include sampling before and after the scrubbing using a multi-sample point gas analyser.

Data logging and Industrial Interfaces.
Measured data are displayed on its large colour display and automatically logged to the internal SD card with user definable interval period. Data outputs are available via Modbus RTU, 4-20 mA analogue outputs ( up to 40 individually configurable)  and most of the common industrial interfaces such us Profbus, Ethernet and Profinet.
In addition to all this, the SWG100 BIOEX can provide up to 20 alarm relay outputs, fully configurable, which are trig by a user define above/below value. Typical application include CHP’s engines Oxygen trip/protection.

Plug & Play Sensors.
The plug and play pre-calibrated sensors technology allow the user to replace all the sensors on site in just under a couple of minutes, dramatically reducing the downtime of the gas analyser. Additional features such as the over-write available on the analogue output minimise CHP’s engine disruption in case of analyser malfunctioning.

Service Contract.
Eurotron Instruments UK limited offer an extensive range of onsite service contract tailored made to suits the requirement of each customers.
