Single-point level switch
The simplest solution for thin-walled containers 1/4" thick (6 mm): the ELS-1100FLG series liquid level switch. The sanitary flange series requires no threaded holes for installation. Insert it into a 0.75" (19 mm) small hole, then tighten the nut and it's done; the high-quality gasket ensures a reliable seal. This is an ideal choice for thin metal walls, molded containers, and medical applications.
