Aquarian 3000Visual Bi-Colour Gauge
Illuminator Series 2 and Display
The Aquarian 3000Visual is a high pressure ported water level gauge used to
measure the water level in high-pressure boiler steam drums. The ASME Boiler
and Pressure Vessel Codestates that “ ported gagesor end-connectedstrip gages,
shall be equipped to afford obvious visual discrimination between the appearance
of water or vapor in the individual sections.” The Solid State Bi-Colour Gauge
Illuminator and Display attach to the 3000 psi 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. Thered/green image is produced by
an array of solid-state light emitting diodes (LED’s) and precision lenses that focus
the image through the gaugebody onto the display. TheLED’s replace the unfocused
incandescentlight bulb and colored glass that are currently used in conventional
bi-colour illuminators.
The LED arrays and precision Plano-convex lens provide a bright, clear and
unmistakable image in the presence of steam and water. Thehigh intensity narrow
beam LED’s are mounted on an electronic printed circuit board with current limitin g
resistors. A precision 24VDCpower supply provides the Illuminator with the exact
current that is required for a constant clean image.
