Fluidwell D074 DIN Panel mount - Level / Pump Controller


Fluidwell D074 DIN Panel mount - Level / Pump Controller with one control output

The D074 is a basic, panel mount 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 hysteresis around the preset value is the result.


  • Unique, robust IP66, IP67 (NEMA Type4X) panel mount front enclosure made of die-cast aluminum, allowing even big jets of water and total immersion.
  • Familiar easy operation with the Fluidwell "Know one, know them all" configuration structure, saving time, cost and aggravation.


  • 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 values can be set by the operator or being password protected.
  • Level: six large 17mm (0.67) digits.
  • Selectable on-screen engineering units for level: L, m³, GAL, USGAL, kg, lb, bbl or no unit.
  • Auto backup of all settings.
  • Ambient temperature: -40°C to +80°C (-40°F to 176°F).
  • LED backlight option.
  • Aluminum DIN front panel of 144 x 72mm (5.67” x 2.83”) according to DIN 43700 / IEC 61554.
  • Various accessories are available for this product.


  • The D074 fits in basic on/off level control applications (e.g. for filling-up a container) without PI(D) control.
  • Very suitable when the required level changes frequently (e.g. for emptying a well or tank).
  • The D-Series is a DIN-sized display and the better alternative for your existing, not waterproof, front panel mount indicators in extreme weather outdoor applications or e.g. in food industries where working environments are often cleaned with powerful water jets.
