F126-EG

Safe area / Intrinsically safe - Flow Computer for gas

with temperature and pressure compensation for corrected volume

Product description

The F126-EG flow computer has been developed to calculate corrected gas volume at normal conditions. The corrected volumetric flow is calculated by measuring the uncorrected volumetric flow, actual line temperature and pressure which are processed with the equations stored in the flow computer. A compressibility factor can be set to approach a real gas behavior. The reference conditions can be defined as desired (e.g. 15°C or 60°F and 1.013 bar).

The display shows the compensated flow rate, total, accumulated total and the actual line temperature and pressure. On-screen engineering units like Nm³ are easily configured from a comprehensive selection.

Advantages
  • Robust aluminum or stainless steel 316L field enclosure (IP65, IP67 / NEMA Type4X) .
    It is so rugged, a truck can even stand on it!
  • Intrinsically Safe available - ATEX and IECEx approval for gas and dust applications.
  • Familiar easy operation with the Fluidwell "Know one, know them all" configuration structure, saving time, cost and aggravation.
  • Very diverse mounting possibilities: walls, pipes, panels or directly onto outdoor sensors.
