TwinSonic-Plus Ultrasonic Gas Meter
The TwinSonic-plus is a two-in-one redundant multi-path ultrasonic gas meter for custody transfer measurement of natural gas.
TwinSonic-plus
Volatile prices and tight margins pressure gas companies to manage costs, increase uptime and reduce risks. Efficient custody transfer is a focus of this effort and high accuracy and reliability in metering are key differentiators for midstream operators. The need for consistent measurements and reliable, robust metering solutions can make all the difference. Honeywell Elster® TwinSonicplus ultrasonic gas meters have market-leading technology delivering insight to natural gas custody transfer applications.
How does this ultrasonic gas meter work?
TwinSonicplus relies on Q.Sonicplus USM market-leading technology. The meter’s patented six-path configuration provides flow profile recognition, superb noise immunity, and unbeatable pressure and gas velocity abilities.
The ultrasonic meter quickly identifies fouling or liquids inside the pipe. With four double reflection paths (swirl paths) and two single reflection paths (axial paths), the primary measurement provides compliant fiscal measurements even in case of a failure of one path of each type (axial/swirl).
Continuous verification of this primary measurement is achieved using additional 100% redundant electronics and dual-path configuration built into the meter body. Two single reflective (axial) paths for verification support the primary measurement, providing greater confidence in the final measurement.
