OK, I am shopping around for a Pressurized CO2 system, and most of my info has came from here and A DIY CO2 system. I was looking at the recent post about a CO2 regulator, needle valve, solenoid valve, and bubble counter for $89.

What is a Solenoid valve, is it something that controls of the flow of CO2 to the aquarium, like an on/off switch?

What is the bubble counter for and what does it do?

Are both these parts really necessary for a pressurized CO2 system, the bubble counter and solenoid valve. I can see the use of the solenoid valve by saving CO2. Thanks for any replies!
