Foxboro Digital Coriolis Mass Flow and Density Transmitter

The new Foxboro digital Coriolis mass flow and density transmitter prevents users from having to take extraordinary steps to remove gas from liquid streams.
The Foxboro CFT51 Digital Coriolis Mass Flow and Density Transmitter is an enhancement to the CFT50 that introduced game-changing technology in the area of Coriolis flow metering. When combined with a Foxboro Model CFS10 or CFS20 mass flowtube, the CFT51 forms an I/A Series Mass Flow and Density Meter. The CFT51 uses HART or Modbus protocol for remote communications, as well as digital signal processing (DSP) techniques that provides enhance flow meter performance and adds new features over previous transmitter versions.
Product overview:
The two-phase capability of the CFT51 prevents users from having to take extraordinary steps to remove gas from liquid streams; provides the capability to start and finish empty batching; and facilitates tanker and railcar unloading applications. It has the fastest response time in the industry, making it suitable for fast batching, as well as for small-volume proving that is prevalent in upstream oil & gas markets. The transmitter introduces required online validation capability and pressure compensation for high-pressure, high-accuracy applications and is the enabler for some unique upstream oil & gas solutions, as well as for bunkering applications.
Key capabilities:
  • Patented DSP techniques allow continuous two-phase measurement, partial empty tube conditions, start-from-empty batching, online flowtube verification and online pressure compensation;
  • User-configurable, externally powered I/O types isolated from each other include analog current output and alarm, frequency or scaled pulse output, contact output and contact input;
  • Quadrature pulse output for custody transfer applications;
  • User-selectable HART or Modbus communication via LCD indicator pushbuttons;
  • Remote communication with HART communicator or PC-based configurator;
  • Transmitter is backward compatible to existing CFS10 and CFS20 flowtube installations;
  • Enclosure meets NEMA 4X and IEC IP66/67 ratings;
  • Transmitter certified for use in hazardous area locations and agency plate includes CE mark.
