F111 Safe area / Intrinsically safe – Dual input Flow rate Indicator / Totalizer
The F074 is a basic level indicator / pump controller that works with a preset value and two switch points to control a pump or valve. The low and high level switch points are entered as a percentage of the preset value to switch the device on / off.
Measure. Monitor. Repeat.
For better insights, better decision-making and better process performance.
Key Features & Benefits
- Two competely separated flow rate / totalizers.
- For each flow one scaled pulse output.
- Displays total, flow rate and product I.D. simultaneously.
- Large digit selection for flow rate or total.
- Flow rates: seven 17mm (0.67″) or 8mm (0.31″) digits.
- Totals – resettable: seven 17mm (0.67″) digits.
- Accumulated totals – not resettable: eleven 8mm (0.31″) digits.
- Separate engineering units for flow rates and totals on the display.
- 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
- For those applications where two indicators are required but one single and compact enclosure 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 +70°C (-40°F up to 158°F).
Advantages
- Robust aluminum 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.
