Field of application

The Flow-X flow computer provides gas and liquid volume, mass and energy conversion, event logging, parameter logging, and reports using latest technology. Identical modules are combined in different housings, offering a multi-run version Flow-X/P for 1–4 metering runs with a local touch screen, or the Flow-X/S version for cost efficient installations. Flow-X meets the requirements of even the most demanding applications and is the ideal partner for custody transfer measurements.

  • Custody transfer, fiscal and allocation gas and liquid measurement

  • On- and offshore, natural gas, LNG, flare gas, process fluids, CO2, H2

  • Loading and un-loading


Device properties:

  • Configurations for meter runs compliant to international standards incl. MID, OIML, AGA

  • Powerful modules for demanding applications

  • Each module features CPU, memory and equal in/outputs

  • Intuitive user interface for graphics display and web browser

  • True remote access via Ethernet

  • Station computer for up to 8 meter runs

Benefits

  • Reduced planning and installation costs through standard configurations

  • Very accurate volume conversion with multiple calculation cycles per second

  • High reliability through independent modules with their own volume conversion and storage of measured values, counter readings and events

  • Easy extension of installations with modules featuring equal in/outputs and 100% software configuration

  • Reduced service and maintenance costs with tamper-proof remote maintenance

  • Cost-efficient and flexible system integration of multiple streams
