Instead of being open/close, you should have the option of being able to set floodgates to a certain "height" aka 1/7, 3/7, 6/7, and the floodgate will only let water pass to the other side if it is above this height.

Even if it assumes that a floodgate that isn't completely open was impassible, I think it would be a nice addition.

Or  add a new option like a flow control gate or pipe that would only only a certain amount of water through it.

Can't you basically accomplish this through pressure plates already?

[groo]

Pressure plates pretty much don't work at all with fluids right now because the coded delay between the trigger and the effect is broken in combination with rapid, random fluctuations of fluid levels over the plate.

Ummm wouldnt a flodgate with states still work as a U-bent? Meaning that due to the teleporting nature of the water the water levels before and behind the Floodgate would equalize pretty fast? A valve-like mechanik would be needed that limits the flow by the desired high. This means that water flows only if behind the valve the waterlevel is not higher then the desired level(s).

Not if the volume of water is not sufficient to submerge the floodgate. It would just flow over the valve until nothing above the valve level was left.

Can you think of a case where this is true and the same effect couldn't have been achieved by reservoirs and floodgates as they are now?

Not saying this is a bad suggestion I'm just having trouble trying to work out where I'd use it.

[Mel_Vixen]

Well for example in dorfcomputers where you set 7 as hig and 4 as low value (or even a (Fuzzy)logic with 4 states).

The flooding of fields might apply too.And if we get fishfarms and rice a field that has constant 2/7 is a must have.

But the most important question is "Why not?".

Oh and the current Preassureplate soltion has some problems with fast changing waterlevels delay times etc.

Stuff like this is easy you just have a reservoirs that is 7/2 squares smaller than where you are flooding.

As I said "Not saying this is a bad suggestion I'm just having trouble trying to work out where I'd use it." as in I couldn't think of how it would help with my insane projects and so I was asking others for examples.

The problem with the reservoirs that the water on your field evaporates. a semi constant replacing of the water is needed.

[groo]

It's not necessarily a bad thing to only have to build one floodgate with a flow control as opposed to two floodgates with a metered reservoir between them.

I can imagine using this to fill my cisterns at a slower pace so that they don't flood when whatever Urist McLeverpuller that tasks my floodgate control lever decides to take the longest, stupidest route to get to it. Proper floodgates can be configured to only allow water through at a particular rate, so why not the ones in the game?

I've not noticed anything over depth 1 having that problem. Although depth 1 would be a use for it, now all we need is crops that require submersion.

This is not a rate control suggestion. It's a depth control. It wouldn't make it flow any more slowly while it's over the depth of the flood gate. I think rate control would be a more useful addition though.

You could use depth control to have an 'overflow' outlet to your cistern mind you.

[groo]

Wait... 

Think I was looking at the last sentence of the OP. Well, depth control I could still kind of see a use for... maybe... though I think I'd prefer the situation with fluid-sensitive pressure plates be fixed, because most of the situations I can imagine it in would involve remote triggers.

Ahh I see, maybe your right. I assumed that meant to limit the level after the gate to a certain amount, but it could well be a flow rate too.

A search for "floodgate height" revealed this has already come up several times.  Please try to build on the previous discussions below:
