Gary Williams, Technical Director at Saflame, comments: "There were a number of design hurdles that needed to be overcome but thankfully flow control for the gases was easy to solve. The support from Bürkert was excellent which meant that our design team could spend more time on the other aspects of the project. "The Bürkert product really was a plug & play item with its connectivity allowing direct control through our GRX SCADA system, which allows the parameters of each experiment to be recorded and Once the design specification had been or actual value changes within 100ms and finalised with the university, the project also maintain its high sensitivity, even at needed to become a reality which low flow rates. Three Type 8713 MFC's, one meant sourcing all of the components for each gas, were incorporated into the to build the rig and making sure that design and connected to the GRX SCADA the finished product would deliver the system, which allowed each MFC to be precision required for scientific research independently programmed, controlled data. Saflame approached Bürkert with and monitored during each experiment. replicated if necessary. The MFC's proved to be easy to set up and following some commissioning and training with the university, the combustion rig has been performing perfectly." the specifications for the gas control system and following the consultation, Bürkert suggested the Type 8713 mass flow controller (MFC) for gases, which was ideally suited to this project. The Type 8713 is a compact device which is designed to provide precise and consistent results, based on Bürkert's 60 years of experience in measuring, controlling and regulating fluids. It uses CMOSens® technology to accurately measure the gas flow rate allowing it to control a set point Dr Troy Manning, who gave the initial design specification to Saflame, commented "We have worked closely with Saflame to ensure that the finished rig would fulfil our requirements. As part of a research project, it is crucial that we can record all of our base data and also repeat experiments with a level of precision that allows meaningful, reproducible results to be collected."
