DIY Bluetooth Fuel Manager

What are the liquid connections? The manufacturers say its a female thread but they have some sort of nipple sticking out in the photos.

It works really well. I get a flow reading of about 3-5 liters/hour at idle.

I haven't hat any issues with fuel restriction at WOT.

I would not consider the connection to be female. It's like the connection on my water separator. It's a litle metal nipple/nose/tube that goes inside the fuel hose.

Send me a PM with your address and I will send you one.

Thanks for the offer, but i have already ordered one yesterday!
He accepted my best offer of $24

He said they have been used on kindey dialysis machines measuring saline and bicarbonate solutions.

Got my microstream flowmeter today.
is yours 1 pulse per 450 micro litres? I make that 2222.22 pules per litre. Do you agree?
Any update on the android app?

[MaleBuffy]

Could be OK. What number does it say on the sensor? Go with that number. I found it to be accurate.

I have made another version that calculates mean consumtion instead of instant, but it's in a early stage. Nothing to make public yet.

[Simon666]

Finally a free weekend without rain so i thought i would get this sorted out.

I ran some tests on the Micro Stream flow meter using the calibration script.

1000 grams of Water at 14°C (1 litre):
Test Count Time
1 2197 2m 08 sec
2 2198 2m 10 sec
3 2197 2m 13 sec
4 2194 2m 09 sec
5 2196 2m 13 sec

737 grams of Petrol at 15°C (1 litre)
Test Count
1 2168
2 2163
3 2166
4 2161
5 2160

I was shocked to see how close together the results are. This is one accurate sensor!

I was surprised to see how freely the liquid passed through the sensor too. No fuel starvation issues here.

I squeezed the hose down with a clamp to a slow drip of about 1 drip/sec and the sensor still counted. Very nice.

That's why I bought 6

Hi everyone, sorry if I take this old post again very interesting, I would like to ask Malebuffy, if I am still present in this forum, that I have problems compiling the code for Android
Using Processing 3.5.3 and related SDK package installed automatically during installation, I have copied and pasted from your blog, the error I get is the following:

Hi,

I am currently on a business trip. I will look into it in a few days time!

[tomcat21]

Hi Malebuffy, I am very happy with your answer, I made your beautiful project, which remains blocked due to that error
good sea thanks

Still not back but have you tried this correction from the blog in one of the comments?

Hi thx for the code.
I want to change the Mph to Km/h so tried to compile the code.
I used Sketch 3.2.3 with SDK 7.1.1

Unfortunatly but got an error on the locationmanager code: locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Changed it to: locationManager = (LocationManager)getActivity().getSystemService(Co ntext.LOCATION_SERVICE);
Now i don't get the error and can Compile.

Another problem, the app displayed very small (1cm/1cm)
Think it has to do with higher android version.
Added the following two lines at "// Set Background and Alignment" to get it right.

size (displayWidth, displayHeight);
textSize(displayWidth/15);

Haven't tested yet but looks like it is working now.

Hi,
sorry but I had not seen this correction ,yesterday waiting for your news I had found and installed Processing 2.2.1 and installed its SDK and Android 2.28 manually, this compiles the sketch correctly without errors, but when I launch the app on the phone it stops immediately
PS. I did not find the Ketai libreiria in versions 11 and I had to insert the latest version 13 .... is it good?
On my phone I have the version of Android 8 with which version of Android in Processing I have to fill out?

Thankyou

[tomcat21]

in any case, should that code correction be made?

The problem is that Android has developed and the my code not. I might update it but for now I will guide you though fixing it as it is. See although you havent given me information about the crash, I think it could be because as of Android SDK over 23, GPS access must be requested by the device and granted by the user. This is missing. The code tries to access GPS and gets an error. Can you confirmthis? If that is the case just use a lower android SDK try 23 or 22. Tell me if it worked.

[tomcat21]

the stop app is immediate, no GPS access request is provided

[tomcat21]

where can I see the crash log on my phone?

You dont see it on the phone. You see it on the PC when the phone is still connected.
