SFC3000 Flow Computer

INTRODUCTION

The SFC3000 is far more than just a dedicated flow computer. It can operate on a number of levels from a supervisory machine to a standalone flow computer or as a system component. With its touch screen, VGA display and extensive processing capabilities, combined with simple to use controls and unique operating software it can function as a complete station supervisor integrated into a flow computer housing.

Designed specifically to meet the needs of the world wide liquid hydro – carbon and gas measurement markets, the SFC3000 is intended to positively contribute to both management and conservation of the world’s dwindling energy resources by providing both versatile and accurate measurement and incorporating state of the art designs and components.

Ex~i Flow Measurement’s SFC3000 Flow Computer was developed using the latest manufacturing techniques to offer a flexible and customer-oriented capacity whilst maintaining high levels of quality. Individual electronic circuit boards and assemblies are handled as completed components and are fully tested and programmed prior to storage. This means that spare parts are usually available from stock. All units are assembled to order, and soak tested for at least 2 weeks.

We normally keep sufficient components to manufacture 100 machines at any one time and our facilities give us the capacity for at least 75 SFC3000 Flow Computers per month. In 2019, more than 500 units were manufactured, tested and delivered to our clients.

TECHNOLOGY

  • Multiple 32-bit μProcessors
  • Surface Mount technology and Multi-layer circuit boards
  • Colour Full VGA 5.7” touch screen display
  • 360° Navigation control
  • Expandable SD card memory
  • Multiple high-speed Ethernet connections: Web enabled – Modbus over TCP I/P (optional board required)
  • Front Panel high speed USB connection
  • Simple to use Windows® based configuration software

CAPABILITY

  • The versatile Stream I/O Board versions fit all measurement application types and supports the use of standard meters such as Ultrasonic, Turbine, Orifice and Coriolis.
  • Each Stream I/O Card provides the complete capability for a single stream fiscal flow measurement with redundant inputs and a two-stream capability for non-fiscal applications.
  • Up to 5 I/O cards can be fitted in the SFC3000 chassis providing a 5-stream fiscal capability.
  • As well as a high speed 32-bit central microprocessor unit to perform all the display and calculation tasks, the SFC3000 has individual high-speed 32-bit processors on each plug-in card to perform the measurement, communication and input/output functions.
  • The SFC3000 maintains the highest accuracy and uses double precision (64 Bit) floating point numbers throughout for all calculations. It also boasts an impressive true half second cycle time.
  • Local configuration and data downloading are achieved using the supplied Windows® software, through the dedicated front panel high speed USB communication port.
  • Remote communication is via the communication card or Dual Ethernet card, with RS232/485 serial capability and Ethernet 10/100 connectivity. Multiple communication cards can be installed.
