The Ex~i SFC3000 flow computer offers multi-stream measurement of gas flow

The SFC3000 flow computer may be configured to provide a multi-stream measurement solution for gas flow. Using a SFC3000 to make multiple sample point measurements can offer cost savings by allowing a single emissions analyser to make sequential measurements from many different sample points.

With additional I/O option boards, the number of streams measured by the EX-i SFC3000 flow computer can be increased up to 5. While it is possible to have multiple streams on a single I/O board, fiscal measurements require one stream per board. If more than 5 streams are required these can be spread over more than one flow computer and the data collated together using the supervisor features of the SFC3000.

The optional I/O boards also have output functionality to allow the control of, or information to be passed to, other parts of a system via pulse or status digital outputs and 4-20mA outputs. With the addition of a communication board, data can also be passed to other systems via the communication board ports, such printers or DCS. Data can also be obtained from a gas chromatograph or other source via the serial or ethernet ports.

Optional boards include

·       I/O digital Stream Boards

·       I/O Analogue Stream Board

·       I/O Switch Stream Board

The SFC3000 is a highly versatile liquid hydrocarbon and gas flow measuring device capable of operating in a stand-alone single stream flow measurement system or as part of a highly complex multi-stream system and offers a great deal more than 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 worldwide liquid hydrocarbon 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.

The SFC3000 flow computer should be considered the “brains” of a flow measurement system and requires a number of peripheral components to take measurements.
