Robust level switches with flanged fittings for dependable liquid level detection.

Flanged float switch­es pro­vide a bolt­ed, pres­sure-rat­ed con­nec­tion for lev­el detec­tion in tanks and ves­sels oper­at­ing under pres­sure, where a thread­ed fit­ting is not suit­able. Avail­able with 1 to 4 floats on a sin­gle stem, with ANSI rat­ings from 150lb to 1500lb in RF, FF, and RTJ face types, and ATEX, IECEx, and UKEX approvals.

Flanged Level Float Switch - 1 Float

A sin­gle float on a flanged stem for point lev­el detec­tion in pres­surised tanks and ves­sels — com­mon­ly spec­i­fied for high-lev­el alarms, low-lev­el cut-outs, or pump pro­tec­tion where a sin­gle trip point is all that’s required.

Flanged Level Float Switch - 2 Floats

Two floats on a sin­gle flanged stem, typ­i­cal­ly used for pump start/​stop con­trol or paired high/​low alarms — deliv­er­ing two inde­pen­dent switch­ing points through one tank pen­e­tra­tion rather than two.

LFS303

Flanged Level Float Switch - 3 Floats

Three inde­pen­dent switch­ing points on a sin­gle stem, well suit­ed to low / high / high-high alarm schemes or three-stage pump sequenc­ing — giv­ing fuller lev­el cov­er­age with­out mul­ti­ply­ing flange pen­e­tra­tions or com­pro­mis­ing ves­sel integrity.

Flanged Level Float Switch - 4 Floats

Four switch­ing points on a sin­gle flanged stem, designed for full fill-and-emp­ty automa­tion, redun­dant alarm tiers, or duty/​standby pump con­trol — con­sol­i­dat­ing com­plex lev­el log­ic into one assembly.
