Flow-X Flow Computer

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.
