14 Safety instructions
14.1 Intended use
The KDF-9/KDG-9 variable-area flow meter may be used only for flow measurements of fluid and gase-
ous media. The manufacturer shall not be liable for damage that may result from improper or unintended
use.
When dealing with an aggressive medium, clarify the material durability of all wetted parts.
14.2 Installation, start-up and operating personnel
Only trained specialists authorized by the system operator may carry out the installation, electrical instal-
lations, start-up, maintenance and operation. They must read and understand the operating manual and
follow its instructions.
Basically, follow the conditions and provisions applicable in your country.
15 Packaging, storage and shipment
Carefully unpack the device to avoid damaging it. With the help of the delivery note enclosed in the pack-
aging, check whether all technically relevant data coincide with your requirements.
Storage and installation must be done in a clean and dry room so that contamination – especially of the
interior of the fitting – is avoided. Follow the limit values for ambient temperature.
When transporting the device to a remote mounting location, we recommend that you reuse the factory-
issued packaging and the transport protection.
16 Maintenance
If you use the meter in the intended manner special maintenance is not necessary. However, the variable
area flow meter should be checked in the context of the routine maintenance of the facility and the pipe-
lines. You have to eighth especially for dirt, corrosion denudation, mechanical wear as well damage at the
glass cone. We recommend checking the meter once a year.
In the recurrent pressure test of the system, the maximum allowed pressure test PT (see name plate)
must not be exceeded.
