Aquarian 3000 Visual Bi-Color Water Level Gauge

The Aquarian 3000 Visual Bi-Color Water Level Gauge is rated to 3000 psi (207 bar) and produces a red/green image to indicate the water level in a high-pressure steam drum.

The ASME Boiler and Pressure Vessel Code states “ported
gages or reflex gages that use refraction of light to aid ready
determination of the liquid level, may omit the requirement
for overlapping sections.”

The solid state bi-color gauge iIlluminator and display
attach to the ported gauge to produce a red or green image on the display. A red image indicates that steam is present and a green image indicates that water is present. The red/green image is produced by an array of solid-state LEDs and precision lenses that focus the image through the gauge body
onto the display. The LEDs replace the unfocused incandescent light bulb and colored glass that are currently used in conventional bi-color illuminators.

The LED arrays and precision Plano-convex lens provide a bright, clear and unmistakable image in the presence of steam and water. The high intensity narrow beam LEDs are mounted on an electronic printed circuit board with current limiting resistors. A precision 24VDC power supply provides the Illuminator with the exact current that is required for a constant clean image.
