F126-EL
Safe area / Intrinsically safe - Flow Computer for liquids
with temperature compensation for corrected volume
Product description
The F126-EL flow computer has been developed to calculate corrected liquid volume at normal conditions. The corrected volumetric flow is calculated by measuring the uncorrected volumetric flow and actual line temperature which is processed with the thermal expansion coefficient algorithm stored in the flow computer. The reference temperature can be defined as desired (e.g. 15°C, 20°C or 60°F).
The display shows the compensated flow rate, total, accumulated total and the actual line temperature. 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.
