F-Series: 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.

Advantages
  • 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.

  • 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!

Level Inputs

  • (0)4 – 20mA.

Control Outputs

  • Function: Control output to control a pump or valve, according to the high / low level switch point values.
  • Type: One passive NPN transistor, active PNP transistor or isolated electro-mechanical relay.

Applications

  • 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.
