Foxboro Coriolis Mass Flowmeter Now Certified for International Custody Transfer Applications

April 142005
FOXBORO, MASSACHUSETTS, USA - April 14, 2005 - Invensys Process Systems announced today that the Foxboro CFT50 Digital Coriolis Mass Flow Meter has been certified internationally for custody transfer applications. The CFT50 is certified by the Norwegian Metrology Service (NMS) for indoor, outdoor, and mobile measurement of mass flow, volume, and density. It is approved for flow measurement accuracy of 0.3 or 0.5 for custody transfer of liquids ranging in temperature from -220 degrees C to +180 C. The NMS represents the International Organization of Legal Metrology (OIML) in Norway and follows OIML standards and procedures. The OIML is a worldwide, intergovernmental organization that oversees the regulations and metrological controls of 22 European member and affiliated countries.

Featuring patented Coriolis flow measurement technology, the Foxboro CFT50 provides uninterrupted, accurate flow measurement with partially empty tube conditions, a traditional problem for custody transfer flow measurement.

"Accurate measurement of materials processed during custody transfer is important to both buyers and sellers," says Joseph E. Downey, director of marketing, Invensys Process Systems, Foxboro Measurement & Instrument Division. "By minimizing wasted materials left on the bottom of transport vessels and improving transfer yields, the CFT50 provides more accurate material accountability, which is a direct contribution to bottom line performance. This is win-win situation for both entities involved in the transaction," says Downey.

Conventional Coriolis meters typically either render inaccurate measurements or stall when they encounter two-phase flow containing both gas and liquid. The CFT50's ability to handle two-phase flow makes it ideal for applications such as liquid CO2, which can flash to gas phase during transfer, and for emptying tank cars, where high volumes of air come through with the liquid being transferred from the bottom of the tank. The Foxboro CFT50 can also improve custody transfer of materials with entrained air, including specialty chemicals, petrochemicals, pharmaceutical ingredients, dairy products and any high value or viscous material.

The NMS certificate of approval for custody transfer applies to the Foxboro mass flow meter system consisting of the CFT50 digital Coriolis transmitter and Foxboro CFS10 or CFS20 flowtube sensors.

The CFT50 transmitter is based on patented microprocessor technology developed through a collaborative program between the Invensys Process Systems and Oxford University in the UK. The proprietary technology involves new signal processing techniques used to provide useful measurements of both mass flow and density, and the operational aspects of keeping the Coriolis meter running stably in single-phase or two-phase flow conditions.

The CFS10 is a single path flowtube design for use with shear-sensitive fluids and for applications requiring positive cleaning. The CFS20 is a dual path flowtube for most other applications. Both flowtubes are available with 3A Authorization for sanitary applications.
