Meter keeps running during two-phase flow
The new Foxboro CFT50 Coriolis mass flow transmitter features patented technology that allows Foxboro mass flow meters to continue operating during two-phase flow.
Flowmeters solve tricky two-phase challenges
Three companies will receive free Foxboro CFT50 digital Coriolis flowmeters as a result of their applications for the "Bring it on" challenge.
It is approved for flow measurement accuracy of 0.3 or 0.5 for custody transfer of liquids ranging in temperature from -220 to +180 C.
The NMS represents the International Organisation of Legal Metrology (OIML) in Norway and follows OIML standards and procedures.
The OIML is a worldwide, intergovernmental organisation that oversees the regulations and metrological controls of 22 European member and affiliated countries.

Flow transmitter doesn't suffer from trapped gas
A novel digital Coriolis flow transmitter can accurately measure flows containing entrained gas, without stalls, or stoppage even when starting or finishing batches with an empty tube.
High stability for novel pH sensor
Foxboro has a new family of pH sensors designed to improve operation in traditional problem areas within harsh process applications.
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 and Instrument Division.
"By minimising 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 make 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 programme 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 shear sensitive fluids, and in applications requiring positive cleaning.
The CFS20 is a dual path flowtube for most other applications.
Both are available with 3A Authorisation for sanitary applications.
