I started using Quantum Tanks to store my liquids (FTB Ultimate pack). I use liquiducts to pipe the liquids from the Quantum Tanks to their target locations.

Is there a way to measure/display/meter the liquid level in Quantum Tanks? I know I can walk up to it and right-click it to see the interface, but I am more interested in sending a signal when the amount of liquid gets below/above a set point. I'm guessing it is not possible, but I thought I would ask in case someone had a solution.

    As with everything quantum, Quantum Tanks obey the uncertainty principle - once you figure out how much is inside, you won't know what is inside any more :-P

  • Are you playing on a server or singleplayer? (If singleplayer, you might consider installing OpenCCSensors and using its Tank Sensor Card, which works on Quantum Tanks. The downside is maintaining a customised install.) Jul 23, 2013 at 19:08

    @SevenSidedDie I am playing on a server, so unfortunately I cannot modify anything. That sensor card sounds pretty cool though! Zommuter lol!

  • This may seem dumb but have you tried comparators?

  • @new The comparator is from 1.5 and FTB is back on 1.4.7. Jul 24, 2013 at 18:31

In the ultimate pack for feed the beast you can use a Nuclear Control Liquid Sensor Kit and a computer how full a tank show it visibly without any extra addons.

I'll post some example code and pictures when I get home from work but if you wrap a nuclear information reader as a peripheral you have a .get(slot) API which gives you the required information, more information on the Misc Peripherals thread.

  • Oooh - this sounds neat! I haven't played with Nuclear Control yet. I will have to pursue this - and yes, if you have example code and pics, that would be awesome!
