F112
- Fifteen point linearization of the flow curve
with interpolation. - 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).
The F112 is a versatile flow rate indicator / transmitter and totalizer with the ability to precisely linearize the flow meter 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.

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, salty atmosphers and temperatures between -40°C up to +80°C (-40°F up to 176°F).
Liquid flow measurement with mechanic flow meters 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.
