Fluidwell F112 Flow Rate Indicator/Totalizer

Intrinsically Safe with linearization, analog, and pulse outputs :

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

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.

Features :

  • Fifteen-point linearization of the flow curve - with interpolation.
  • Accumulated total - not resettable: eleven 8mm (0.31") digits.
  • Analog and pulse outputs.
  • LED backlight.
  • Displays total and flow rates simultaneously.
  • Flow rate: seven 17mm (0.67") or 8mm (0.31") digits.
  • Total - resettable: seven 17mm (0.67") digits.
  • Ambient temperature: -40°C to +80°C (-40°F to 176°F).
  • Separate engineering units for flow rate and total on the display.
  • The remote control input to reset the total or to lock the “clear total” button.
  • Intrinsically safe according to ATEX and IECEx.
  • Large digit selection for flow rate or total.
  • GRP, Aluminum, or high-grade stainless steel enclosure.
  • Auto backup of settings and running totals in EEPROM memory.
  • 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).
