General safety instructions
In all work, the existing national regulations for accident prevention and safety in the
workplace must be complied with. Any internal regulations of the operator must also be
complied with, even if these are not mentioned in this manual.
Never operate the flow switch in systems which have a greater flow rate than the speci-
fied max. flow rate (
it will cause irreparable damage to the flow switch.
Ensure that the medium is free from magnetic particles.
Suitable measures should be taken to prevent the medium from freezing.
If the flow switch is to be used in ambient temperatures of <4 °C, do not carry out any
operation beforehand with pure water, e.g. a test run. Residual water in the flow switch
can result in frost damage.
No greases, oils etc. should be used during the installation of the VKX... devices due to
the material resistance.
Ensure that the max. specified operating pressure is not exceeded.
Never remove a flow switch or its body from a pipe system under pressure.
If the medium which is to be monitored is very hot, the flow switches or their connection
fittings will also become very hot. In this case, neither touch the flow switch nor place any
heat-sensitive objects in its vicinity.
Protect the flow switch against external magnetic fields in the immediate vicinity, since
these can impair device functioning.
It is prohibited to remove or make type plates or any other information attached to the
equipment indecipherable, otherwise all warranties and the responsibility of the
manufacturer no longer apply.
