Batch Control


Fluidwell F-Series Batch Controllers


The F-Series range offers five different batch controllers for the accurate dispensing of small amounts of liquids up to the loading of trucks with two-stage control or analog multi-stage control. The Delivery Controller is specially designed for the delivery of unknown quantities of product; it can be used for all kinds of products from gasoline and oils to windshield fluid. All F-Series batch controllers have a self-learning overrun correction for repeatable results under varying conditions.

All F-Series models are available for safe area and hazardous area applications

Flow Switch Monitoring

Annunciator For Flow Switch Monitoring

The Vigilante® II annunciators are compact, panel-space saving, easy to use annunciators available in models to handle either four or eight flow switches. Each switch can have its own custom message, such as "Low Flow Alarm", on the Vigilante. When a flow switch trips, the LED for that input flashes, a horn sounds and a relay transfers. The Vigilante annunciator can even indicate which switch tripped first.

  • Monitors four or eight flow switches
  • Powers the flow switch
  • Free custom message labels
  • Built-in horn
  • Two Form C 2 A relays
  • Shallow Depth 1/8 DIN Case
