Ideal for allocation and check metering, the fully-redundant Rosemount JuniorSonic 3412 Two-Path Gas Ultrasonic Flow Meter combines a dual-bounce path design with powerful 3410 Series Electronics to ensure a superior non-fiscal measurement solution. This cost-effective meter is wet gas tolerant and features rugged Rosemount T-21 Transducers that are engineered for wet, rich and/or dirty gas applications for reliable, long-term performance. Innovative MeterLink Software ensures operators have easy access to the diagnostics generated by the meter for real-time detection of flow disturbances.
