Ultrasonic Flow Meter - the TUF-2000B

@ downerhouse

The project was previously built with ESP IDF v4.4. I just pushed an update which fixes build errors to compile with IDF v5.0.1 but note: it is otherwise untested.

In any case, before you start with any IDE, I recommend you get it building from the command line so you have a better understanding of what's happening behind the scenes.

• Install ESP IDF to a directory
• Run a command prompt
• cd <PATH_TO_ESP_IDF>
• setup.bat
• cd <PATH_TO_GIT_REPO>
• esp.idf build

That's all you should have to do. Good luck!

Many thanks for the tips and update. I've spent all afternoon trying to compile it in VSCODE before I saw your reply! I wondered why I was getting build issues

I've also got a weird problem where the ENV variables are not getting recognised, so I've been hard coding some of the folders to get around it for now.

Made some progress, but will now look at the updated code.

My ultimate goal is to integrate the data with a robo-tank setup I'll be commissioning with my new tank in the next couple of months on the return line.

Managed to get it compiled this morning using your stock firmware, thanks a lot. Next step is to make a few changes to support my needs. Thanks for your help (and the source code). Saved me a lot of time.

How do you determine the spacing of the sensors? I'm looking to install one and am having a rough time figuring out the spacing of the sensors

Hi all, I'm hoping some of you with experience using the TUF-2000B can help (@NoleP and @KWolfe81, are you still out there?).

I bought a new TUF-2000B but it came TL-1 transducers for large pipe instead of the advertised TS-1 for small pipe (I am using standard 1-1/2" PVC potable water pipe). I installed the large transducers anyway to experiment while waiting for the correct ones and the display reports "No Signal Detected" after entering my pipe OD, wall thickness and pipe type into the menu.

Can anyone say if this is expected given I'm using the large transducers? Also I'm also not using any acoustic coupling gel (I thought I was getting gel in the box but I couldn't see any in the photo from @KWolfe81 so hoping it may not be necessary).

Thanks in advance for any suggestions.

Cheers,
Dale

You need to enter your pipe parameters and transducer configuration (V, W, Z etc.) into the TUF-2000B menu and then it calculates the required sensor spacing.

Any more/long term feedback?

Looks like @KWolfe81 hasn't been on the forum in 1½ years - anyone else in this thread willing to share anything they have learned? I bought the same flowmeter, an ESP-32 board, and couple of both MAX485 and MAX3485 (after seeing there could be issues using 5V signals).
I am a complete newbie at all this stuff, though I build computers and learned programming many years ago. My plan is to tie the flowmeter into a new Home Assistant system, so I am all over the Internet trying to educate myself... Any resources greatly appreciated, hope I haven't bit off more than i can chew!

Thanks!
