Level and Flow specialist ALLISON ENGINEERING has been appointed exclusive UK representative for AWITE, the German market leader in dedicated Bio-Gas process analysers. The agreement means Allison Engineering takes responsibility for sales, service and maintenance of the Awite range in the UK, ensuring total, dedicated support on a local basis for all systems supplied.

With increasing volumes of UK waste now being processed to create biogas from AD (Anaerobic Digestion), Bio-gas plant operators need to ensure that working capacities are maintained and optimised. From small agricultural sites to larger industrial AD plants, accurate and dependable online gas composition analysis is an essential part of this process and the Awite range provides a wide choice of options.

The range comprises the Awi-Eco, a low cost, compact discontinuous analyser which provides 50 CH4 and CO2 measurements per day, with 4-20mA output and USB connection. For more sophisticated monitoring and analysis requirements the Awi-Flex provides continuous measurement for CH4, CO2, H2S, O2 and H2. This system provides up to 5 measuring points; Ethernet, Profibus, Modbus and USB connection. Most importantly, it can also be used to take flow, temperature and pressure inputs and undertake automated desulphurisation control.

All Awite analysers utilise a rugged, touch screen industrial interface which allows easy access to recorded data, sensor parameters and system diagnostics. This ensures that all information is instantly available, remotely.

Commenting on their appointment, Jeff Harwood, Director at Allison Engineering said, “Awite process analysers are an important addition to our range of level and flow instrumentation products and we look forward to helping Bio-Gas plant operators achieve optimum monitoring and analysis of their process flows”. He added, “Awite have over 800 analysers operating at sites throughout Europe providing measurements of CH4, CO2, H2S, O2 and H2. We believe that what sets their product apart from other analysis equipment is their compact, low-maintenance design and flexible configurations, these systems can carry out control functions through fuzzy logic and PLC interface”.
