N-Series: N410

DIN Panel mount - Batch controller

with numerical keypad, remote control inputs and 3 control / alarm / pulse outputs

The N410 batch controller distinguishes itself by its user-friendly features: Numerical keypad, clear programming menu structure, easy to read display and simple mounting enclosure. The numerical keypad allows simple and fast changing of the preset batch quantity. Fluidwell stands for simplicity and reliability and it is now available in this customer focused and application driven batch controller.

  • Save time and cost with the easy to operate numerical keypad.
  • Your crew is in control with our highly praised "know one, know them all" configuration structure, saving time, cost and aggravation.
  • Key information at a glance as the display simultaneously shows actual value, preset value, batch process indication, switch point indication and measuring units.
  • Easy installation with the rugged aluminum DIN-size panel mount enclosure.
Application overview N410


  • Full numerical keypad.
  • Shows actual value, preset value, batch process indication, switch point indication and measuring units simultaneously.
  • Five control inputs for remote START, HOLD, RESUME, keypad lock and external alarm.
  • 7 large digits (14mm, 0.56") for actual value, flow rate and total.
  • 10 smaller digits (8mm, 0.3") for preset value, accumulated total and batch count.
  • Selectable on-screen engineering units for volumetric or mass: L, m³, USGAL, IGAL, ft³, bbl, kg, Ton, lb.
  • Easy operation to enter a batch value and to control the process.
  • Easy configuration with clear alphanumerical display.
  • A Just-In-Time back-up stores the latest batch information in case of a power failure.
  • No-flow monitoring.
  • Automatic overrun correction.
