Fluidwell F126-EL Flow Computer with Temperature Compensation

General Information

The Fluidwell F126-EL Flow Computer with Temperature Compensation 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.

Fluidwell F126-EL Advantages

• Robust aluminum or stainless steel 316L field enclosure (IP66, 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.

Fluidwell F126-EL Features

• Calculates compensated flow rate, total and accumulated total based on a temperature/expansion relationship.

• Analog output signal reflecting the corrected flow rate.
• Displays total and flow rate simultaneously.
• Flow rate: seven 8mm (0.31″) digits.
• Total – resettable: seven 17mm (0.67″) digits.
• Accumulated total – not resettable: eleven 8mm (0.31″) digits.
• Temperature: six 17mm (0.67″) digits.
• Engineering units for flow rate, total and temperature on the display.
• LED backlight.
• Intrinsically safe according ATEX and IECEx.
• GRP, Aluminum or high grade stainless steel enclosure.
• Auto backup of settings and running totals in EEPROM memory.
• Ambient temperature: -40°C to +80°C (-40°F to 176°F).
• Various accessories are available for this product.

Applications

• Applications where net flow calculation of liquids at normal conditions is desired without the influence of thermal product expansion.
• The F-Series is your first and best choice for field mount indicators in safe and hazardous area applications. Especially in harsh weather conditions like rain, snow, sandy deserts, salty atmospheres and temperatures between -40°C up to +80°C (-40°F up to 176°F).
