Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

LS FLOAT NO

IEEE / ANSI

ANSI/IEEE float level switch no symbol

The float-operated NO form connects a discrete electrical action to a defined liquid-level mechanism. The drawing must identify the vessel or location and the direction of level movement that actuates the contact.

Form evidence

Autodesk IEEE-oriented Miscellaneous Switches functional form. Autodesk explicitly publishes this block under IEEE Symbol Preview. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

Float level sensing is different from a continuous analog level transmitter.

LS FLOAT NO

Symbols

Float level switch NO

A float-operated NO level switch changes contact state through a float mechanism at a documented fluid level. Schematics need the rising or falling level action as well as the contact reference state.

A distinction that matters

A float switch is a discrete level device rather than a continuous level transmitter.
