Hi,
This is about the AquariumPlants.com's Electronic Co2 Regulator.
AquariumPlants.com's Electronic Co2 Regulator
It has an electronic valve that opens and closes in a fraction of a second, (each "opening & closing" equates to a bubble) and, due to the fact that it is "electronic" the "bubble rate" can never change
They claim it as the ultimate way to get rid also of the dumping we see in CO2 at the end of the life of canister, or with external reactors depending on the pump flow
I thought at it for a while, then found a suspicious issue, letting me think it is only crap commercial claims. Here's an extract from an email I sent them:
I never got an answer, despite their claims they can be freely joined and answer all requests.
Just a warning to move your way from such products claiming to be the best in the world. Bubble rate isn't all in CO2 injection. Needle valves have their bps varry depending on pressure. This electronic valve, in my opinion, will have a variable flow despite a fixed bps. So, you won't even be able to monitor the changes before you see your plants die or your fish gasp on surface

Also, I have one question about your electronic box precision:
When the pressure of canister drops or the outside pressure changes, the gas flow velocity through your valve will change. So, even for a same speed of on-off of the box and for the same diaphragm/bubble size specified, the end bubble size will varry, unless your box have some inside pressure control. This is the same problem with mechanical needle valves. In your case, bubble speed won't change, but gas flow, hense, bubble size would definately varry the same, just invisible to user. Am I wrong in my suppositions?
