Tank Status Monitor.
This does what it says on the can - monitors the status of tanks. It's self explanatory to use, just run it and it tells you what to do.

Features:

• Does not crash when you destroy the tank!
• Supports all tanks with getTankInfo support! (that means railcraft tanks and then some)
• Colors status bar based on liquid! (It uses pink if it's not in my table of liquids)
• Live!
• OpenPeripheral support for the latest version! (Trust me, I test with the latest version)
• Supports every liquid in Minecraft and with mods that use Forge's liquid API!
• Multiple tanks in one display! Use the -m command line option.
• Large tanks don't go offscreen!
• Networking cable support!
• Use -g to use TERMINAL GLASSES!
• TG does not go offscreen!

Requirements:

• Advanced computer/turtle/monitor
• A tank
• OpenPeripherals

To do:

• Add more colors for liquids (primarily TConstruct molten liquids)
• Better looking tank diagram
• Multiple tanks on one display at once added!
• What you guys want

feedback please?

I get an Error attempt to index ? (a number value)

Looks promising. But would be nicer if the screen was not white and instead fill the entire monitor background as the liquid color.

IMO more like this: http://www.computercraft.info/forums2/index.php?/topic/15689-dead-simple-railcraft-tank-monitoring/

Does it also support vertical monitors?
