A water supply and sewerage utility company serving the south west of England have been investing in renewable energy sources to reduce their carbon footprint and aim to have 97% of all the sludge they process digested in some form by 2019. Their biggest renewable energy source is the methane gas produced in anaerobic digesters, which are used to treat sewage sludge. The bacteria in the digesters break down the organic material in sludge to produce biogas, which is fed into combined heat and power engines. Our Badger Meter RWBG and RNBG Hybrid Vortex meters are being rolled out across several sewerage treatment sites. The RWBG is a wafer-style inline vortex flow meter and the RNBG is an insertion vortex flow meter, both optimised for low pressure Bio-Gas applications, typically CH4 + CO2 mixtures and offer highly accurate measurements (±1%). These meters have no moving parts and are virtually maintenance-free once installed. These models are loop-powered with standa...
