The RNG Series meter is an insertion-style gas flow meter designed to offer high accuracy measurements over an extremely large flow range. The meter has no moving parts and is virtually maintenance-free once installed. The RNG series is suitable for most gas types, including compressed air, natural gas and wet or "biogas" applications. All meters in this series are loop-powered devices with standard HART® communications for ease of field programming and system integration. Through the use of an internal RTD and an external pressure sensor (optional), the flow meter software will compensate for changes in pressure and temperature, to achieve an accurate mass flow measurement.
