Product description
3.1
Flow-X flow computer
The Flow-X flow computer consists of 1 to 4 Flow-X modules (Flow-X) and an enclosure
(Flow-X/S, Flow-X/P or Flow-X/C). For a Flow-X/S or Flow-X/P enclosure, the Flow-X modules
are exchangeable whereas for a Flow-X/C, the Flow-X module is permanently installed inside
and therefore cannot be exchanged.
3.2
Flow-X Module
The Flow-X module is the core element and represents the complete gas flow computer. It
represents a measuring section in a gas measuring system. The Flow-X module is operated
in a Flow-X/S, Flow-X/P or Flow-X/C enclosure. It has its own 4-inch display and four
navigation keys which serve to check values and change parameters.
