Optex Water It TC-3000-DI Instruction Manual page 9

Suspend the sensor so that
it is not hung vertically.
An optional mounting attachment (TA-1,
TA-1SP) is prepared for users who use
the sensor at a place at high water flow.
This attachment serves to prevent a
sensor from impinging upon a side wall or
turning around.

・ Read the precautions in the "TA-1 instruction manual" carefully.
・ Attach the cable protective cover without fail. Otherwise, there is a
possibility that a cable is scratched during maintenance operation and
water intrudes.
・ Do not hang a sensor with the sensor cable.
・ Do not cover over measuring surface by the hanging attachment.
・ When installing TC-3000SP-D, keep the metal part of the sensor away
from the surrounding metal.
Use attachment TA-1SP when using the product where water flows fast.
Using attachment TA-1 may accelerate corrosion.
