Fluidwell F126-EG Intrinsically safe -Flow Computer

The F126-EG is a high-performance flow computer designed to calculate corrected gas volume at normal conditions. By measuring uncorrected volumetric flow alongside actual line temperature and pressure, this device processes signals using stored equations to deliver precise net gas flow data.

Description

Precision Gas Volume Correction The F126-EG flow computer is engineered to handle the complexities of gas flow measurement. It calculates the corrected volumetric flow by integrating data from the uncorrected flow, line temperature, and pressure. To approach real gas behavior more accurately, a compressibility factor can be set within the system. Operators have the flexibility to define reference conditions as desired, for example, 15°C or 60°F and 1.013 bar.

User-Centric Design and Rugged Build The device features a clear display that shows compensated flow rate, total, accumulated total, as well as actual line temperature and pressure. Configuration is streamlined through Fluidwell’s familiar “Know one, know them all” structure, saving time and reducing cost and aggravation during setup.

The enclosure is exceptionally robust, available in aluminum or stainless steel 316L (IP65, IP67 / NEMA Type4X), and is so rugged that a truck can even stand on it. This durability makes it the first and best choice for applications requiring resistance to extreme temperatures ranging from -40°C up to +70°C (-40°F up to 158°F).
