RWBG Wafer Style Vortex Flow Meter :: Bio Gas

RWBG Wafer Style Vortex Flow Meter :: Bio Gas

RWBG Series Wafer Style Vortex Flow Meter for Bio-Gas measurement

RWG Series meters are wafer-style in-line flow meters designed to offer high accuracy measurements with extremely low pressure drop. The RWBG model is similar in construction but optimized for low-pressure “BioGas” applications, typically CH4 + CO2 mixtures. The meters have no moving parts and are virtually maintenance-free once installed. The RWG series is suitable for most gas types. The meters in these series are loop-powered devices with standard HART® communications for ease of ÿeld programming and system integration.



► Optimised for Bio-gas (eg.: CH4 + CO2)
