Flow-X Flow Computer
Brand: Endress+Hauser
Xpert The Flow-X flow computer provides gas volume conversion, event logging, parameter logging, and reports using state-of-the-art technology. Identical modules are combined in different housings, offering a multi-stream version Flow-X/P for 1 - 4 measuring distances with a local touch screen, or the version Flow-X/S for smaller installations with one measuring distance. It is the ideal partner for custody transfer gas metering solutions in installations with FLOWSIC600 ultrasonic gas flowmeters.
- Custody gas metering
- Demanding natural gas and process gas applications
Device properties:
- MID approved configuration for gas metering streams with FLOWSIC600
- 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 multiple streams
- Reduced planning and installation costs through standard configurations
