10.4 Float
The float is an essential component of the level transmitter, which must be matched to the
medium in terms of density, pressure strength and material resistance.
The floats listed below are interchangeable and can be reordered individually. Further float
models and materials are available on request.
▶
The density and magnet position of floats of the same type vary slightly, so that
readjustment may be necessary.
▶
All floats can also be used with a pressure of -1 bar (vacuum).
