How much wood chips?

[JohnZ]

I have a Masterbuilt propane smoker that has a three section round pan for holding wood chips. It seems that filling the pan up as I did a couple times produced way too much smoke and wasted most of it.
How much do I really need to add each time it needs to be refilled? One section , two sections or all three.
I'm somewhat confused about how much smoke needs to be produced during smoking times.
i guess it depends on the kind of meat/ poultry being smoked.
