Fluid
If there is detection fluid, set so that
dark state is effective.
No fluid
If no detection fluid, light state.
Installation
• If only the Fiber Unit is installed, proceed according to the fol-
lowing basic procedure.
• Detection of level differences to a minimum of 4 mm is pos-
sible with the following installations.
• Do not expose the fiber unit to undo forces such as pulling
or compression (no more than 0.1 Nm).
• The bending radius of the fiber unit should be no less than the
allowed bending radius (both rated and performance).
• When securing with the band, take care that the fiber is not de-
formed.
• If an opaque pipe is used, this may result into incorrect opera-
tion.
• Water drops, air bubbles, or clouding in the pipe may cause in-
correct operation.
• If the background exerts an effect, use the anti-reflection
sheet (accessory) (see the diagram below). The anti-reflec-
tion sheet also serves to prevent shifting due to fiber unit vi-
bration.
Miscellaneous
Polycarbonate is used in the case. Do not allow contact with
chemicals such as alkalis, aromatic hydrocarbon, or chloro-al-
iphatic hydrocarbon, as these will dissolve the case.
