Safety information

2.1 General information

Before commissioning, check the condition of the instrument and any accessories
supplied. Before commissioning, please read the user manual. Ensure that the instrument
is suitable for your application.
To guarantee safe operation, the instrument may only be operated in accordance with the
information in the user manual. When the instrument is in use, the statutory and safety
regulations required for the particular application must be complied with. By analogy this
also applies to the use of the accessories.
If the instrument is not handled correctly, or if the operating instructions and specifications
are not adhered to, damage to property or personal injury can result.

2.2 Intended use

The series HFS 250 and 2500 instruments are designed to monitor a continuous flow of
fluids. Any use extending beyond or deviating from this shall constitute improper/non-
designated use. Unless otherwise indicated, the instrument measuring scales relate to
water. With particular regard to applications with intermittent loads (e.g. pulsed operation),
please consult our technical sales department beforehand, so that the necessary checks
can be made.
Series HFS 250 and 2500 instruments must not be installed as the sole means of
preventing dangerous conditions on machines and systems.
Machines and systems must be designed in such a way that error conditions cannot lead
to a dangerous situation for operating personnel.

2.3 Qualified Staff

HFS 250 and 2500 instruments should only be installed by qualified personnel, properly
trained for the suitable use of these devices. Qualified persons are those individuals who
are familiar with the set-up, installation, commissioning and operation of these instruments
and who have the appropriate qualification for this function.
