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 standard HART® communications for ease of field programming and system integration.
Badger Meter’s vortex flow meters utilise ultrasonic technology to measure tiny vortices that form when media in the pipe move across a bluff bar. The number of vortices formed is directly proportional to flow rate. Badger Meter’s vortex flow meters offer the smallest strut in the industry, which allows for high levels of sensitivity, superior performance at low flow rates, high turndown ratios and low pressure drop.
