The Flow-X is the first flow computer to support GERG-2008, the most accurate and versatile equation of state for natural gas.

The Flow-X/M module is the single stream building block for all Spirit flow computer products and enclosures with each module provides more than sufficient communication ports and IO for any oil and gas meter run

Its configuration and operation is touch screen based where a single screen can be used to access multiple flow computers. Remote access is possible from any web client over a secure HTTPS connection.

The complimentary Flow-Xpress software allows for virtually unlimited customization of the comprehensive gas and liquid applications (available in metric and US customary units).

The Flow-X provides advanced control functions for additional system savings: embedded flow, flow/pressure, valve and sampling control functions eliminate the need for a PLC or a sampler controller.

The Flow-X integrates seamlessly with our measurement automation software eXLerate, creating a Power Package that enables smart metering solutions.

And there is Flow-Xplore, an out-of-the-box Human Machine Interface for metering stations with Flow-X flow computers.

FLOW-XPRESS CONFIGURATION SOFTWARE

To match the large variety of requirements for fl ow computer functionality in today’s international markets, Flow-X is supplied with a unique confi guration and test tool, Flow-Xpress™. Distinct levels of expertise for users are recognized, ranging from novice users to demanding expert level engineers, who create their own applications.

Using Flow-Xpress, a user can simply confi gure the fl ow computer by setting vital parameters, such as meter type and Modbus mapping. With Flow-Xpress Pro, an expert user is enabled to develop a dedicated application, utilizing the userfriendly and familiar spreadsheet oriented development environment.

Flow Computer Configuration

Calculations, displays, reports, alarms, Modbus or HART communication interfaces and much more can be freely defi ned from a rich library of functions and tools.

Template applications are fully user defi nable. Predefi ned confi gurations from a directory of templates can be used to easily match existing fl ow computer applications.

Ready-to-run application templates are available for both liquid and gas applications with MID approvals from the Dutch Metrology Institute NMi.

Testing and Debugging

A unique feature of Flow-Xpress is the application simulation and debugging tool. This allows transparent local and remote online and offl ine simulation of a Flow-X application on detailed level. Report and display layouts, including the local Flow-X/M LCD display, as well as the touchscreen interface can easily be simulated, tested & previewed.

FROM NOVICE TO EXPERT USER LEVEL

Integration & Connectivity

Flow-X supports various communication protocols, such as: HTTP, Modbus Master & Slave, RTU & ASCII, Modbus/TCP Client & Server, HART Master, UNIFORM, ASCII and other protocols for maximum connectivity.

Easy integration is ensured, even with complex SCADA / HMI systems. The Flow-X series software has a natural fit with eXLerate® Metering Supervisory software.
