hi instead of a mofset could i use an L298N motor driver?

You a genius!!!!

Tutorial?

I think it worked! Thank you.

Does the sound reflect of the water surface or the bottom of the well? I read that sound is reflected of water only at a critical angle.

Genius! This saved me from having to mess with fishing line and weights.

What a legend. Thanks Peter. Anyone used a laser distance meter successfully is my next question.

Tea-asty 🤣🤣🤣

Love it any information on parts used? I would be interested in glass or ptfe versions of parts. Brass air fittings and that pvc tubing I think will react with stuff too much

I have a 6" well pipe 2 ft sticking out the ground, this does not work. The pipe just rings like a bell blocking out any echo

I'm a believer? THANKS

Hello - A blast from the past! Great approach! So I tried it but my numbers don't make sense. I have a cement cap shallow well. I tried filtering the sound file but still cant get numbers that make any sense. Any thoughts?

Fair play man! Getting the job done!

Wow, worked like a charm! I used an app that saved it as a .wav file so I didn't have to do the conversion, then used Audacity.

@Peter Maginot Would you have instructions on how to construct this? Atm I'm not sure how you connected a motor for rotation.

Thanks for the marvellous solution. I was thinking of purchasing a laser distance measurement instrument. However I am not sure whether it would have worked.

This actually works very well (pun intended ...).

Can you do it if the well is capped with concrete?

Peter, I have got to thank you. Since we are in a water drought here in Oregon, some property owners wells are running dry this season. I figured I better check the static level of my well, to avoid burning out the pump, and, if need be, make the necessary arrangements for a dry well. I looked at a lot of different methods, from cheap to expensive, but nothing caught my interest until your very simple (GENIUS) method. Thanks to you, I found the static level easily, and can check it periodically to avoid surprises. My normal static level is at 28ft, and using your method I found the static level to be 35 ft. My pump is at 61 ft., so I can rest easy for now thanks to you. Thank you so very much.

Excellent!

#Thanks for providing the demo about new method of detecting water Depth inside the Borewell. #Accordingly please clarify the following; Is it "possible to record/capture the sound wave* *correctly*??- 'inside the Borewell', *if there is *some gap in top cap- enclosure*,as cap made with two halves* ( top cap to casing pipe of borewell not fully closed). #Please reply.

very clever. Smartphone sonar for well depth!

have you done any updates with this? Me personally would just get a second potentiometer that matches the factory one and have it right in the pedal. Ive been wanting to do this for a while but got too busy with other stuff. Seeing this makes me want to dig it out of the pile!

Thank for the great post and video. The quality of the knocking sound is surprisingly good to enable a valid automatic time delay and distance measurement. We use the knocking sound in the video to demonstrate how to automatically measure the water depth using autocorrelation here at www.virtins.com/forum/viewtopic.php?f=24&t=1842&p=2692#p2692. Thanks again for the great video.

This is genius! Will be trying this

Sounds like (no pun intended!) someone could write an app for a smartphone to do this! Will try it out asap - thanks!

solvents and plastic seem a bit on the worrisome side but I have plenty of mason jars. sanitary pipe or glass are a lot more available in 2020. but this does a great job of getting the idea of how simple this can be.

Amazing. I just calculated the depth to water surface in my well using cell, switch sound converter and audacity. I didn't want to open the top of the well and drop a line down when science could easily solve the problem. I am using the information to calculate how much bleach I'll be putting into the system for a chlorine shock I am going to do. THANK YOU :).

I measure the depth of the water using a $2 ball of string and a bottle half filled with water. Just lower down the bottle until the tension ends - its floating. Measure the amount of string in the well by bringing it back up.

I actually used this and it works way better than I had thought it would. Thank you for the tip! my water is at 375' and thats way easier than trying any other method I have found.

Nice. The distance between the flask and the condenser should be as short as possible tho.

Fantastic!

genius

You got more money tied up in Brass fitting and plumbers tape than the Campbell-Hausfield compressor costs!

I was wondering what Macgyver would be up to in retirement...now I know.

I would be interested to see someone use a string and bobber now and see how far off this is. If at all. Thanks for this though, science is awesome.

Complete a video with a test. I can make a boat going to the moon but I will not show you if it is working. Just like that.

You seem very smart. Question: is it possible to use a power washer to run a high power misting system?

You should check out my screw together power washer it's all right on my channel if you like it I would like to know what you think about it I think your ideas really awesome by the way so I've had this comment up for a couple of weeks and haven't gotten any response for you from you so I'm just going to go ahead and assume that you're not watching your comment section on your Channel everybody needs to go and watch my video it's way better than this. Mine doesn't require check valves all kinds of crazy dancing and tanks and all the moving parts that you have in yours mine has 0 moving parts and it will fit in your hand .you can adjust how much or how little are or how much or how little water is Ultimate detailing super tool and everybody needs one if they use a power washer to make money for a living check it out so special note to the Creator if you ever watch this and read this comment I would be interested in combining my gun with your system to see just kind of what kind of results so I would get I would be more than interested in doing some type of collaboration if I don't hear from you I'm going to do it anyways sometime this summer so cheers

Boom!!!!!!!!!!!!!!!!! Noooooooooooo shiiioiiiiiiiiiitttttt! Rest in peace sir.

Wonderful technique that just worked for me. The sound file from my Huawei P9 Lite was the M4A that I converted using the online solution audio.online-convert.com/convert-to-wav. Opened it in Audicity and it came in 1m from the string estimate. Thank you boss.

Neat

1000 psi........ Wow , looks more likes bomb than a pressure washer to me. Well done

For my deep well this didn't work, it seems to just measure my casing depth accurately, but doesn't reflect back from the actual water level (estimate around 300-400 ft). Further research led me to this device for anyone else interested: www.enoscientific.com/estore/index.php?route=product/product&product_id=74 The posted method here though may work for shallower well levels.

This is genius. We have a sketchy well that we were trying to measure. Your method worked perfectly and saved us a lot of hassle. Thanks.

Well done. Thanks for sharing!

Great setup!

i took the time to make one of these and i must say it is amazing.you can just whip up batches of lsd all day long.i made so much i compressed it into a small nelson mandela shaped oval .i lubed it and inserted it into my nostril.its like micro dosing for wellness.

Oh hell no! plastic and aluminum? no no no no no the only thing other than glass in a rotovap system should be high quality stainless steel and even then no
