Flow rate Monitor and Totalizer Fluidwell F018

Flow rate Monitor and Totalizer Fluidwell F018

The flow rate monitor F018 is a local indicator/transmitter with linearization, that displays the actual flow rate, resettable total, and non-resettable accumulated total. The F-Series is known worldwide as a range of user-friendly indicators. The F018 is even more impressive. The HART communication allows you to communicate in an easy way with smart "DD enabled host" systems.

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.


  • 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, 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.


  • Displays total and flow rate simultaneously.
  • Fifteen point linearization of the flow curve - with interpolation.
  • Two-alarm values can be entered: low and high flow rate alarm.
  • Large digit selection for flow rate or total.
  • Flow rate: seven 17mm (0.67") or 8mm (0.31") digits.
  • Total - resettable: seven 17mm (0.67") digits.
  • Accumulated total - not resettable: eleven 8mm (0.31") digits.
  • Separate engineering units for flow rate and total.
  • Red flashing LED backlight in case of a flow rate alarm; intensity adjustable.
  • Displays clear alarm messages.
  • Scaled pulse output reflecting the accumulated total.
  • Intrinsically safe according to 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 a clear alphanumerical display.
  • Ambient temperature: -40°C to +80°C (-40°F to 176°F).
  • Various accessories are available for this product.
  • F018 on the HART Foundation website.


  • Flow rate monitor 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).
