Hello Didier,
I want the photos please sometimes that zhom would be ok to tinker a little.

@tautin
Verification made, based on your indication (1 turn = 30 g on the dosing screw), by setting 3 as the wheel turn (000 mm, or 3 m), we will have 000 km = 3 kg
In my case (mounting at the outlet of the silo extraction screw), I still have to determine my parameter. The principle being the same, find a number which is an easy multiple of the development of the wheel ... But for that, I will fill the silo, then empty it and locate the "distance". Result in a year!
On the other hand, your 30 g per turn of the dosing screw, you have perspective now. This is confirmed ???
Your sensor is well placed on the top gear, the one immediately after leaving the tank? Because the one, at the bottom, which turns the screw which feeds the burner has fewer teeth, it therefore turns faster ... I can't find the photo on your site !!!

Hello...
The photos, no problem, I'll take them. Put them online, I'll see what I can do - nuance!

Here are 2 or 3 photos:
It's pretty simple:
1) remove the screw and the washer which is at the end of the extraction screw and which retains the reducer which carries the motor ...
2) replace it with a threaded rod, first with two nuts locked so that the end of the screw has the same length as that removed; re-block ...
3) prepare a flat iron with a hole to carry the magnet; pay attention to the length: do not hang the motor or touch the ground ...
4) fix this metal tab on the threaded rod; I put a system which means that this can block without damaging the extraction screw, a kind of "clutch" (nut, then washer, then rubber washer, then washer, then flat iron, then washer, then nut) ; it holds strong enough for it to turn, but the axis can turn without the flat iron turning ...
5) fix the magnet
6) adjust so that it does not affect the gearbox or the motor ...
7) the sensor is fixed by two brackets; position it close enough to the magnet, without it touching ... I drilled the fixing holes accordingly.
8) the counter is fixed on a piece of wood, on the silo (I recycled a door unit which I no longer needed; it was all ready).
And then that's it.

I confirm that the counter model used, with 10 balls - balls in euros, all the same! - at Décathlon, starts well on the first turn of the screw after going to sleep.
The daily counter is not reset by the standby (you have to "reset" using the appropriate button). So that fits perfectly.
I will soon tackle the counter on the boiler feed screw.

I am in the process of calibrating it by precisely measuring the volume of pellet consumed in the boiler hopper because for the moment, the daily consumption being low, I can easily measure the consumption of the hopper over a day.
see you soon for results.
To benefit from your calibration work: you have mounted your magnet on which axis? I can't find the tautin photo on his site.
- above, on the gear which activates the dosing screw immediately at the outlet of the tank ??? It is the slowest.
- below, under the previous one, the smaller toothed wheel (which therefore turns faster) which activates the screw for feeding the pellets into the burner ???
- or at the bottom, on the right, on the axis which seems linked to the engine, which turns even faster (reduction system behind the sheet) ???

Did,
Here are the photos.
The counting for the parameter 30g / turn is made on the axis of the small bottom sprocket, that of the burner supply screw. My calibration is done on the current year, I think this parameter is quite precise.
The magnet is glued with two-component glue (Araldite) on a disc cut from a piece of transparent packaging. The disc is drilled to be mounted glued to a plastic mandrel. The mandrel is force fitted on the hexagonal screw head of 10 which holds the pinion on the shaft. The mandrel is itself made from a felt cap with a diameter of about 12 mm (green circle in the center of the disc). I found one that mounts pil hair on the screw head. You have to be a little handyman to have a round assembly.
The sensor holder is an electric tube drilled and fixed on a desk lamp holder which is clamped on the frame. The sensor is in my case an ILS (Soft Blade Switch)
The advantage of this assembly is that it is not intrusive, everything can be dismantled without a trace.
I have a small video of the spinning disc. I do not know this I can put it online on this site.

same but on the axis which is in line with the engine. it spins faster.
my reasoning is that we have an interest in having as many impulses as possible: indeed if the meter lacks an impulse at each "alarm clock" (to be sure that this is not the case), I tell myself that as a percentage, it is interesting that this missed impulse represents less.
in this same idea I put two magnets per turn
I made it simple: a cover of sheet metal jam pierced in the center.
the two magnets glued on by their own magnetization and rolls my hen.
I now have fairly precise values by measuring the volume consumed in the cylindrical hopper of the boiler. in the evening, I open the hopper, I smooth the granules well horizontally and I measure the volume consumed during the day.

Thank you for the answer: it is the "wheel" at the bottom, the one which turns the fastest, therefore, which makes the 30 g / revolution.
If I understood Dirk Pitt between the lines, he attacks the dosing wheel, the top one. There should therefore be another factor of proportionality.
Indeed, Sioux, the assembly !!! Without touching a bolt! Unbeatable, with regard to the guarantee!
That said, it would take a lot of bad time, in the case of my assembly, to find a causal link between the fact that I unbolted two nuts and a possible breakdown. Unless it breaks right there, at the reducer, of course ... Probability: a billionth?
Uh, if I may, Belle Hélène, pen cap, plastic packaging, glue, desk lamp: that's secretarial work, isn't it? No reason to wait for zhoms always, right ??? I forgot, must open the hood. There are 4 screws. So there ... I don't know anymore. I have a big doubt ...

But I know how to open the hood dear Didier I don't have both feet in the same hoof (well, rather a stiletto heel than a blonde's hoof) as we say in Berry I just have to find time to stick to it ...... this is more difficult.
And first of all I have to go buy a bike computer
But I follow this post with interest
