Now you're getting too technical for me. I have no idea how to answer that one.
One sensor is in my fugve/sump. Once it drops about an inch, an Maxijet 1200 pumps water to get that inch back. I have a flex hose coming from the MJ1200, then hard piped and elbow. Then, I have a larger (than the elbow) tibe going straight down into the sump/fuge below the water line. That way I get no noise and with the larger vertical hose, there is a siphon break. The second float switch is in the FW
reservoir to prevent the supply pump from truning on if the water level gets too low. HTH
Lemme know if you'd like pics. I can get'm by later this evening.
