These level switch floats were not designed for fine tuning or fine tuning. If you want fine adjustments you must use fixed and non-floating switch (with cable). As someone said in another comment, you must use the "error test" technique to adjust a float. Luck
The counterweight acts as a pivot, the greater the counterweight-float distance, the greater the height of the water. normally float acts 45 ° against the counterweight
OKAY. And with the cable length?
I had this idea in mind:
- With the distance between counterweight and float one regulates "the number of liters" at start and stop ... the shorter, the less "gap". Respecting the 20cms as a minimum required by manufacturer (at least Viyilant). Since I want the tank to empty as little as possible, I leave it at 20 initially.
- With the length of the cable, which definitively defines the depth at which the counterweight remains (the lance is fixed to the float), I define the maximum level of water in the tank (whose height will be the level where the counterweight is + 14cm approx. )
with the cable length you control maximum and minimum levels if you leave the long cable the tank will empty more than if you leave the cable short
If you want the pond to empty as little as possible, leave the counterweight at a height of 20 cm and try, that would be the minimum, that is, the height / edge / counterweight / float height.
Thanks for your answer!
Beyond my desire to learn and / or deduce ... the answer confuses me a little ... first you say that it works only for the length of the cable, and then that the distance between counterweight and floating is the one that gives level .. .
What does the distraction between components affect, and what does the cable length affect?
Thanks again!
no, the position (height) of the counterweight in the tank will tell if the tank is emptied to the bottom or half or a quarter ... then the distance of the counterweight / float will give the amount of water, the greater the separation the greater the amount of water and vice versa
