Rosemount 3417 4+4 Dual-Configuration Gas Ultrasonic Flow Meter
Compteur de gaz à ultrasons double configuration Daniel 3417
Achieve the ultimate in fiscal measurement verification and validation with the fully-redundant Rosemount™ 3417 4+4 Ultrasonic Flow Meter that delivers the power of two field-proven Rosemount four-path, British Gas-design ultrasonic meters (certified to OIML R137 1&:2 Accuracy Class 0.
5) in a single body. This advanced meter generates two independent measurements on one meter run for superior measurement accuracy, reliability and uptime. Innovative MeterLink™ Software provides immediate access to a wealth of predictive diagnostics generated by the meter's ultra-fast 3410 Series Electronics for real-time detection of flow disturbances to reduce measurement uncertainty and simplify maintenance.

Features

  • Expedite flow disturbance detection with patented transducer synchronization that prevents interference and noise
  • Reduce measurement uncertainty with process alerts for wall buildup, liquids, blockage and deviating gas quality
  • Equipped with robust titanium encapsulated T-200 Transducers for optimal performance in wet, sour and corrosive environments.
  • T-200 Transducers are safely extractable under pressure without special tools (for line sizes up to 42")
  • Speed issue resolution with 3D view of the flow profile that indicates swirl, crossflow, asymmetry and turbulence
  • Reduce manual errors with automatic calculations of AGA 8 Compressibility and AGA 10 Speed of Sound
  • Simplify installation with two meters in one body; no need for an additional meter run or intermediate flanges
  • Streamline maintenance, extend calibration cycles and cut costs by easily tracking meter performance to baseline
  • Significantly reduce time previous spent on data analysis and troubleshooting with the new Smart Meter Verification Basic feature now included in the latest 3410 Electronics firmware update
