LIMIT INDICATOR REPLACEMENT (OLDER TANKS)
From DIBt information issue 1/2008
When replacing limit indicators on tanks with test certificates or general approvals of the
building inspectorate, the following limit indicator with the certificate of suitability for intended
use of the building inspectorate may be installed:
•
limit indicators fitting into the designated connection on the tank,
•
limit indicators having such a length allowing for the hitherto adjusting dimension to be re-
configurable and for reading off the related control dimension.
