F074 Safe area / Intrinsically safe – Level / Pump Controller
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
- The display shows the actual level, preset value, high / low switch points and status.
- On-screen engineering units are easily configured from a comprehensive selection.
- Selectable on-screen engineering units for level: ml, L, m³, GAL, USGAL, kg, lb, bbl or no unit.
- Selectable on-screen engineering units for height: mm, cm, m, mtr, inch, ft, mmwk, mmwc, cmwk, cmwc, mwk, mwc, inwc, ftwc, mBar, Bar, PSI or no unit.
- Level: six large 17mm (0.67″) digits.
- LED backlight with adjustable intensity.
- Level control: high / low switch points and a preset value can be set.
- Switch points and preset value can be set by the operator or they can be password protected.
- One control output for on / off pump or value control.
- Intrinsically safe according ATEX, IECEx and CSA C-US.
- GRP, Aluminum or high grade stainless steel enclosure.
- Auto backup of settings in EEPROM memory.
- Easy configuration with clear alphanumerical display.
- Ambient temperature: -40°C to +70°C (-40°F to 158°F).
Typical Applications
- Basic on / off level control applications without PI(D) control requirements. Also very suitable for applications where the required level changes frequently.
- Functions for filling-up a container or emptying a well or tank.
- 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, IECEx and CSA 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.
