There are different types of pressure switches for SMA, and our understanding of the system operating on a pressure switch may differ. Can you tell me if a water level differential of 5 cm in the sump is possible, or is it better to maintain 1-2 cm? P.S. In SMA, there is also not a meter-high column of water.

In SAMP, the differential is usually kept at 1-2 cm. And the water column is about 20 cm there. I once thought about an automatic refill based on this principle, but the sensors that meet the requirements cost a fortune.

Seryoga, you are falling behind progress. It's sad.
