Esdun Industrial 
Designed to minimize fiscal measurement uncertainty, the Rosemount 3415 4+1 Ultrasonic Flow Meter combines the power and performance of a field-proven Rosemount four-path chordal, British Gas-design meter (certified to OIML R137 1&2 Accuracy Class 0.5) with a one-path, reflective check meter in a single body.

Features
- Detect buildup on pipeline walls in real time with sensitive 30°, single reflective path
- Patented transducer synchronization method ensures the flow meter’s electronics provide the highest sampling rates possible without cross-interference.
- Avoid common mode errors with chordal and reflective paths that work in unison
- Reduce measurement uncertainty with process alerts for wall buildup, liquids, blockage and deviating gas quality
- 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
- Increase I/O with new Type 4 CPU Module with up to six frequency or digital outputs
- 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
