You are on to something there...but that still needs measurable head pressure that is sure to get noticed on a flat ditch. Could it be submerged in a total depth of 1/2 meter with siphon outflow at the base? I think i could do a divot in the stream bottom that would not get noticed...hmmm

Closed system using a bucket of water being pumped to the top of the inlet and then returning to the bucket. Im doing this only to test out the dynamics of it, this will be used on a natural water way.
3/4 inch inlet with one straw for air introduction, this is about 8 feet tall
transition to 1 1/2 transfer pipe then to a vertical 3" air entrapment with 1/4 air compression gauge and valve. The air chamber is about 2 feet tall.
The outlet part of the transfer pipe then goes to 1 ". The outlet pipe is about 5 feet tall. I experimented with a one way valve to try and create back pressure. Youtube Mr. Teslonians Trompe Hammer for the gist of this.
No matter what I do I cannot seem to generate more than 1 PSI and of course once the pressure is releases the water level comes up and spills out of the top. I want to test this on actual falling water because I think it has to do with the volume of water going into the inlet pipe, it doesn't seem to be enough since im pumping through a 1/2 tube into a 3/4 inlet pipe.
If anyone has any further ideas/thoughts I would appreciate it and I can post more details if desired. I tried to contact Mr. Telonian but I can't find his contact info anywhere, he would certainly know the answer.
