Detector - Tank

The Detector - Tank is a block from the Railcraft mod. This block is meant to output a redstone signal based on the type of Minecart that passes in front of it. The Detector - Tank will output a redstone signal if a Tank Cart that matches the filter is in front of it. They can be placed under or beside Minecart Tracks, and will output a signal to the side that has a small square. When a redstone signal is active this square will turn red.

Usage
Place a bucket of the desired liquid to create a redstone signal from in the Filter section of the GUI. Then choose the amount parameters.
