F112

Field mount - Flow rate Indicator / Totalizer

with linearization, analog and pulse outputs

Product description

The F112 is a versatile flow rate indicator / transmitter and totalizer with the ability to precisely linearize the flowmeter signal. 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 output signals.

The display shows flow rate, total and accumulated total. On-screen engineering units are easily configured from a comprehensive selection.

Advantages
  • Robust IP66, IP67 (NEMA Type4X) field enclosure.
    It is so rugged, you 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.

Features

  • Fifteen point linearization of the flow curve - with interpolation.
  • Analog and pulse outputs.
  • Displays total and flow rate simultaneously.
  • 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 on the display.
  • Remote control input to reset total or to lock the “clear total” button.
  • LED backlight.
  • 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

  • Liquid flow measurement with mechanic flowmeters where a precise calculation over the full measurement range is required. Also re-transmission of the flow rate and/or totalizer functions or serial communication is desired.
  • 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).
