How to make a Water Level Gauge in 2 minutes for $2

One other possible place to find some tubes, is at your local brew shop, and also at your local physics and chemistry lab supply shop. You can get them in all sorts of sizes and lengths.

a half inch what? A barb?

Chuck the cork, it'll grow stuff. Just fill the bottom of the straw with hot glue, spray foam or silicone.

fantastic idea thanks!!! great for my hydroponic WDC

Absolutely brilliant in its simplicity. However, I doubt if the corks are that easy to find separately.

Simply and perfect!

Another option that is inexpensive, has no moving parts and simple is an "S" curve sight guage. (all measurements are approximate) Get a length of 1/4 (ID) inch clear plastic tubing that is over three times the height of your rainbarrel. Twelve feet of tubing costs less than $10.

1. Weight one end and sink it to the bottom of your barrel.

2. Drill two small holes at the top (above fill line) or run the tubeing into the top.

3. Run the tube out of the first hole to the outside and run the tube to the bottom of barrel and secure. (I run it around the faucet)

4. Run the tube back up to the top and into the second hole (optional). I do this to keep the tube clean as I net the barrel against mosquitoes.

5. Leave about a foot or two of hose inside and make sure it stays above the fill line. The extra length is to suck with. (I secure things with tie-tabs)

6. Suck the water into the tube until it reaches the current water level.

That's It! No moving parts. As the water level in the barrel moves up and down, the water level in the tube will follow

I really need to make one of these for my hydroponic system, but I don't understand what parts are needed. Could you post a parts list? Thank you so very much.

Can you please show this gauge in action. New to all this and have no idea how I'd use it. Thanks.

what is that plastic tube? what type of battery checker is it? thank you for the video

thanks

thanks

thanks

THANK YOU!!! I have been trying or think of the easiest way to make one of these and your video is EXACTLY what I needed! I have a 1700 gallon tank so no straws but it will still work by using plastic tubing or even a lightweight stick of wood capped by a cork!

ingenious. thanks!

Nice idea, you could also just use some P clips set loose enough for straw to slide up and down on a strip of wood.

any ideas for a 1500 gallon tank

Genius!  Simple and genius, that is exactly what I needed to see to figure out my water level problem!  Thank you!

Whats the white fitting called?

sch project

where do u get it -_-

Terrific! I was wondering how to check the level of water in my campervan tank which is opaque blue, and this will do the trick perfectly. Many thanks to you.
