In addition to the average K-Factor or Span, fifteen linearization points can be entered with their frequencies or values. The unit will interpolate between these points greatly enhancing accuracy in any flow range, even for very low frequency applications. This linearization affects all displayed information as well as the signal outputs.

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, IECEx, FM and CSA 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.

Features

• The display shows flow rate, total, accumulated total, alarm values and alarm messages.
• Large digit selection for flow rate or total.
• Displays clear alarm messages.
• Red flashing LED backlight in case of a flow rate alarm; intensity adjustable.
• Fifteen point linearization of the flow curve – with interpolation.
• Two alarm values can be entered: low and high flow rate alarm.
• Flow rate: seven 17mm (0.67″) or 8mm (0.31″) digits.

• Separate engineering units for flow rate and total.
• Scaled pulse output reflecting the accumulated total.
• Intrinsically safe according ATEX, IECEx, FM and CSA C-US.
• GRP, Aluminum or high grade stainless steel enclosure.
• Auto backup of settings and running totals in EEPROM memory.
• Easy configuration with clear alphanumerical display.
• Ambient temperature: -40°C to +80°C (-40°F to 176°F).
• Various accessories are available for this product.

Applications

• Flow rate monitoring with a precise calculation over the full measurement range, where re-transmission of the totalizer and monitoring of the flow rate function and HART communication is required.

• 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).
