Due to statutory regulations concerning protection of the environment and the health and safety of

contact with liquids if it is possible to do so without risk to personnel and environment. This means
that KROHNE can only service your unit if it is accompanied by a certificate in line with the
following model confirming that the flow meter is safe to handle.
If the unit has been operated with toxic, caustic, flammable or water-endangering liquids, you are
kindly requested
• to check and make sure, if necessary by rinsing or neutralizing, that all cavities are free from
such dangerous substances.
(Directions on how you can find out whether the unit has to be opened and then flushed out or
neutralized are obtainable from KROHNE on request.)
• to enclose a certificate with the level gauge confirming that it is safe to handle and stating the
liquid used.
