Hello.
I am honored to present my present work committed in 15 minutes during the performance of works at the end of the world, i.e. in Central Poland.
Needed was a flow meter with pulse output to control the chemistry dosing pump. Of course, there are ready-made flow meters / water meters with such a function, only that within a radius of 30km, they are not immediately available.
The system had a built-in water meter with a mechanical counter, and a reed switch sensor at the pneumatic cylinder position, a small neodymium magnet and a cyanoacrylate adhesive. After disassembling the measuring system, I made a notch in the measuring disk 1dm? / revolution and I put in them a magnet with dimensions of 2x3x3mm. I attached the reed switch to the lid and it was ready:
