In version 15, all fluids would have the same level if not separated by a pump. I'm noticing in 16 that fluids fluctuate drastically, and I'm having difficulty getting fluids from trains to tanks then to refinery.

To demonstrate, here's a series of petroleum tanks. The bottom left, is full and the bottom left pump can't insert any more fluid. The top right tank is at 3/5 (15k) full. In version 15, like I said, these would all have the same level (the same percentage of 100%).





Attached is the save game. There are no mods.

I made attached map in 0.15 to test the difference in fluid leveling in storage tanks in your setup, and didn't observer any difference between 0.15.40 and 0.16.23

Tanks have a bad flow rate. You need huge pressure differential to get liquids into or out a tank fast. In your setup you have that at the entry with the pumps. But not so at the exit or between tanks. So pressure drops of from the first tank to the second, to the last through the pipe until it hits the last chemical plant. Since you constantly take out petroleum gas from the last tank it will never level off.

But who cares? Do yo get enough fluids at the chemical plants? If not add a pump going out of the tank.

posila, mrvn, thanks for taking a look at this.

I ran your test posila in both 15.40 and 16.24 and also showed the same experience, almost to the exact numbers under heavy demand by pumping the liquid to the other end of the tanks. I guess i wasn't putting as high demand on my liquids in 15.40 as I do now.

In a test environment, this runs smoothly. In a game, numbers fluctuate all over the place since liquids enter and exit in so many ways.

Maybe if I want higher numbers at the end of the tanks, is to put pumps there as you have in the series of tanks.

Thanks, I guess it is operating as expected.

Use a single tank to pump fluids in an out. If you need more buffer storage add pumps to the other two connectors with one pump going in set to "fluid < 5000" and one pump going out with "fluid > 20000" connected to more tanks.
