Hi,
Interesting idea (bubbler) that I had not heard of...
So, I really DO want to remotely measure the water level in my well (3 ft diameter, 10 feet deep)..
So, I understand I do this:
- Install a long hose from the wellhead to the house, bring hose inside near my Home Automation computer.
- At the well, connect the hose to a rigid tube (say 3/4 inch white PCV) long enough to reach the bottom of the well.
- At the house connect some piping (regular PCV plumbing stuff) as a "Tee" with one port to a compressed air supply and other port to an electronic pressure sensor (1 atmosphere 15 PSI OK for my shallow well).
- Feed enough compressed air into the system to be sure air is bubbling from the bottom of the well.
- Measure the pressure at the sensor.
Right??
In my case I have compressed air fed to house and barn. My wife resisted having it in the kitchen, dunno why.
So if I use a typical solenoid air valve, I could have my Arduino Mega (usually loafing along anyway) turn on the air, read the pressure and wait for it to stabilize, turn the air back off.
Caculation:
See:
http://docs.bluerobotics.com/calc/pressure-depth/So, for example, 8 feet depth is = 3.47 PSI
So a pressure senor good for 10 PSI or 1 atmosphere would be fine...
Does this make sense?? Errors?
