How to automatic mixing water

[wolf_bluejay]

The original idea about this came from a sampling system for ocean water at different depth -- so pardon me if the idea sounds half baked.


Why bother with a hopper or motor controlled device that can cause problems -- why not have multiple "drops" of measured salt.

In the most simple but costly version: have 5-10 pvc tubes sealed on top with a flapper on the bottom controlled by a small motor each. Into each one goes to correct amount of salt for the mixing tank and all are placed above the tank. For a batch of salt, add water, open 1 tube, mix and serve.

On the cheap you could do a circle of tubes with flappers and a disk on the bottom with 1 hole in it. rotate disk a little and 1 tube opens through the hole.

A little less automatic for a whole bucket of salt, but would work well for 5,10,20 batches that you could measure out all at once and forget it.
