Custody Transfer and Check Metering
Accuracy and reliability in gas custody transfers applications
Peace of mind in fiscal metering with Rosemount Ultrasonic
Custody transfer, or fiscal metering, occurs when fluids or gases are exchanged between parties. Payment and taxation are usually made as a function of the amount of fluid or gas transferred, making measurement accuracy fundamental. In natural gas custody transfer measurement, it is common to see both parties using individual measurement instruments to ensure they receive an accurate account of gas being bought/sold. The Rosemount™ 3416 4+2 Dual-Configuration Gas Ultrasonic Flow Meter and Rosemount™ 3417 4+4 Dual-Configuration Gas Ultrasonic Flow Meter provide customers with peace of mind by combining a four-path meter and an additional 2/4 path meter, all in one instrument. This enables customers to reduce costs by purchasing fewer instruments while ensuring they are getting custody transfer level measurement for all parties involved.

Product Solutions
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.
- Patented transducer synchronization method ensures the flow meter’s electronics provide the highest sampling rates possible without cross-interference.
- 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.

Immediately pinpoint the cause of minor flow disturbances with the Rosemount 3416 4+2 Ultrasonic Flow Meter that delivers the power and performance of a field-proven Rosemount four-path, British Gas-design chordal meter (certified to OIML R137 1&:2 Accuracy Class 0.5) and a two-path, reflective check meter in one body. A highly sensitive, vertical 90° path quickly detects trace amounts of liquid and other debris at the bottom of the pipe that can significantly increase lost and unaccounted for (LAUF) gas. A wealth of predictive diagnostics are generated by ultra-fast 3410 Series Electronics and are displayed via MeterLink™ Software to help detect costly process upsets in real time.
- Detect trace liquid/debris along the pipe bottom in real time with highly sensitive, vertical diagnostic path
- Detect buildup on pipeline walls in real time with sensitive 30°, single reflective path
- Expedite flow disturbance detection with patented transducer synchronization that prevents interference and noise
