Siphon transformed into bubbler and clay balls?

[georges100]

the clay balls are not cooked ...

the plate jhaponaisesx is porcelain, just to make it solid ...

the glass balls cost in the 1 € the bag in sale, it avoids asking questions

If the logs are not cooked then not good

Constant level of water thanks to a brake fluid reservoir (with level cap)

If it is to use the switch attached to the plug, with the tinned copper inside contact that touches the float it does not work long (1 week?). The water is responsible for corroding / eating contact (original it is bathed in oil).
You have to scratch the contacts all the time ....

On the other hand there must be the possibility to remake the contact in stainless steel or to mount a switch with flexible blade (waterproof).
A+

It remains the solution of the pressiostat but I'm not sure of its accuracy, someone tried with it?

I'm not sure what is not cooked, the ones I have have ten years of use in gardening and have not moved ... hence the idea of ​​using them ...

So I ask myself the question, but in fact we must make sure that they hold.

For glass beads, they accumulate heat less well and are not porous so in my opinion less effective. (to have...)

I'll boil it to see the reaction.

theoretically we bake the clay to reduce the porosity among other ....

It is!

A time soon that it heats on the gas .... nothing to report for the moment

Hello yakakliker

It remains the solution of the pressiostat but I'm not sure of its accuracy, someone tried with it?

Test with a washing machine pressure switch with a cadmium steel and plastic body (Emaüs collection):
This is one of the first editing that I have experimented. (It is very sensitive and triggers for a column of water about 30 cm with a hysteresis of 2 or 3 cm?) It can work if the reservoir to be controlled is not too small and the level does not bicolor too much inside.

On the other hand, when the tank is very small, like a flask of looked, the volume of water to be moved in the piping to trigger the pressure switch is not negligible compared to the tank of Looked. Unfortunately there is interference with the pressure switch.

Depending on the% of air or water circulating in the pipe that feeds the pressure switch, the results vary. In fact, this type of pressure switch must be placed "dry" and therefore above the tank. But suddenly, the weight of the water column in the piping significantly influences the results for such low pressures.

Clearly with a small tank and the least bubble is anything. So you have to find a model that can work with the water and below the tank.
A+

Yes, you will say that I am painful ....

Does anyone know if these balls are disintegrating and how fast?

Hello,
They are cooked, that's for sure. But which T °?
So, to know if they will hold up for your use,
You weigh 100 gr dry beads.
You put them in a toilet, you close the toilet with an elastic band, and you put it all in your washing machine on a program at 60 °.
When the laundry is over, you dry your balls, and you weigh ...
There, you will know if your balls are ok for your use
