Honeywell Elster® TwinSonicplus ultrasonic gas meters use market-leading technology to provide accuracy and valuable insight into natural gas value chain custody applications. Unstable prices and narrow margins pressure gas companies to control costs, increase duration and reduce risks. An effective custody transfer operation is key to this effort. High accuracy and reliability in metering solutions have become a key differentiator for mid-range operators and the need for consistent metering and reliable, robust metering solutions can make all the difference.
TwinSonicplus uses market-leading technology from the field-proven Q.Sonicplus USM for its primary measurement. A patented six-path configuration provides detailed flow profile recognition, superb noise immunity, and unrivaled pressure and gas velocity abilities.
Using reflective paths and sophisticated diagnostics, the ultrasonic meter quickly identifies fouling or liquids inside the pipe. Fiscal measurements are fully compliant with AGA9 and explosion approved according to ATEX, IECEx, FM and CSA. With four double reflection paths (swirl paths) and two single reflection paths (axial paths), the primary measurement will provide 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.
