Quantifies Tank Level

  • Ruler-like markings, or graduations, along the length of the gauge board provide a readout of tank volume in conjunction with a Hawkeye indicator, float, and gauge head.

Extruded Aluminum

  • Graduated gauge boards are made from 1/8″ thick extruded aluminum with durable anodized finish for long life span.
  • No sharp edges for safe handling, unlike sheet metal alternatives.

Modular and Segmented

  • Gauge boards ship in 8 or 10 ft segmented modules, for ease of shipping and handling, with a pre-installed splice and fasteners for easy assembly on site.
  • Graduated gauge boards are available standard in 1 ft increments from 4 to 80 ft. Smaller increments available.

Graduation Markings

  • Standard markings report volume in cubic metres [m3].
  • UV-resistant blue vinyl graduation markings or blue screen print enamel markings standard.
  • Other colours are available for vinyl markings, and custom colour transitions are available to indicate internal structures or minimum fill levels, for example.
  • Custom graduations available, with minimum distance between ticks of 2.4″.

Common stock and near stock configurations

  • Stock and near stock configurations have blue markings with standard volume resolution of 1 m3.
