Need an outdoor Bar graph display

[TheWaterboy]

I am looking for an outdoor bargraph display large enough to see from 20 feet away but no more than a foot tall. Its to display a tank level to a driver from across the street. I have seen some from OTEK which I like but its LEDs are too small to be seen from a distance in daylight.

I'm looking for suggestions if you know anything like this.

Have not seen any bar graph displays for outside use that large, but if you could display it in numeric value (percent, feet, meters,etc) magna makes very large displays like the one in this link.

Perhaps something like this: http://www.photonplay.com/outdoor-led-display.html

Depending on the capability of the display you might be able to stand one of these upright and, with the correct signals, operate it like a bar graph.

Depending on the resulution you require, you may get by with a board containing 10 or more LEDs, arranged in a line. use a PLC to trigger outputs based on level. >10% = 1, >20% = 2, etc. You could even use green, amber and red LEDs

Design your own "Daylight Visible" stack light: http://www.bannerengineering.com/en-US/products/112/Indicator-Lights/tl50_config

This will do what you want.
