RWG & RWBG Series Meters

RWG & RWBG Series Meters

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