Measures to be taken when cleaning the tunnel
With FLSE200-M sender/receiver units installed, it is essential to prevent water from
reaching the ultrasonic transducers. Safe protection is ensured by covering the protective
tubes with the supplied caps.
No protective measures are required for the FLSE200-H and FLSE200-HM sender/receiver
units during tunnel cleaning.
When automatic tunnel cleaning equipment (cleaning with brushes) is used, an adequate
distance to the sender/receiver units must be kept to prevent possible misadjustment.
