thank you Sir yea i found it out a little bit later when i looked up the optimal floating numbers ^^ for the nav terminal

Regarding step 2, find out the hull volume by the following steps:

1. Open a submarine in the Submarine Editor.
2. On the menu at the top, select Toggle visibility > Hulls.
3. Those blue rectangles are the hulls, select one of them.

A box should be shown on the top, the Selected hull volume is the value we are finding.

if you talk about step 2 the hull volume you talk about max healt?

The instruction to configure the wait time was wrong.

The correct value to be set in the delay component should be equal to the wait time. That is, 3 seconds delay will make the duct block to open and check the change of water level every 3 seconds.

I have updated the mod’s description.

Sorry for the confusion.
