Fluidwell - Model F074 -Field Mount - Level / Pump Controller with One Control Output
The F074 is a basic level / 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. For pump control applications, the function can be inverted to empty a well. A stable level within a hysterese around the preset value is the result. The configuration of the Span, off-set and number of decimals is done through software functions, without any sensitive DIP-switches or trimmers. 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.
- Robust IP66, IP67 (NEMA Type4X) field enclosure. It is so rugged, you can even stand on it!
- Intrinsically Safe available - ATEX, IECEx, FM and CSA approval for gas and dust applications.
- Programming can be done by your own crew, with the sensible menu-driven structure, saving cost and irritation. Know one, know them all!
- Very diverse mounting possibilities: walls, pipes, panels or directly onto outdoor sensors.
- Level control: high / low switch points and a preset value can be set.
- Displays actual level, switch points, status and preset value.
- 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.
- Level: six large 17mm (0.67") digits.
- 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.
- LED backlight with adjustable intensity.
- Auto backup of settings in EEPROM memory.
- Easy configuration with clear alphanumerical display.
- Ambient temperature: -40°C to +80°C (-40°F to 176°F).
- Various accessories are available for this product.
- The F-Series is so rugged, even a truck can stand on it!
- 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 atmospheres and temperatures between -40°C up to +80°C (-40°F up to 176°F).
- Basic on / off level control applications without PI(D) control requirements. Also very suitable for applications where the required level changes frequently.
Alternative basic models: F070, F073, F077. Alternative advanced model: F173 or the D-Series DIN panel mount indicators. - Functions for filling-up a container or emptying a well or tank.
