F114 Safe area / Intrinsically safe – Ratio Monitor / Totalizer
The F114 flow computer calculates the actual ratio between two separate flows. It has one low ratio and one high ratio alarm value. Special precautions are taken to allow start-up problems and incorrect ratio readings for a certain period of time. Based on the location of the flowmeters, a selection can be made out of six different formulas.

Key Features & Benefits
- Calculates ratio between flow A and B.
- Displays ratio, flow rate A and B and total A and B.
- Ratio monitoring: two alarm values can be set: low and high ratio alarm.
- Alarm values can be changed by the operator or they can be password protected.
- Six ratio calculation formulas.
- Ratio: seven 17mm (0.67″) digits, displayed as 1:__ or percentage.
- Flow rate A and B: seven 17mm (0.67″) digits.
- Total A and B – resettable: seven 17mm (0.67″) digits.
- Separate engineering units for flow rate and total on the display.
- Up to three configurable alarm outputs.
- Displays clear alarm messages.
- LED backlight.
- Intrinsically safe according ATEX and IECEx.
- GRP, Aluminum or high grade stainless steel enclosure.
- Auto backup of settings and running totals in EEPROM memory.
- Ambient temperature: -40°C to +70°C (-40°F to 158°F).
Typical Applications
- Mixing or blending of two components where continuous ratio displaying, monitoring and totalising is important. For example in construction works, roof or wall isolation, gluing and coating.
- 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 +70°C (-40°F up to 158°F).
Advantages
- Robust aluminium 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 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.
