Safety Information
General Instructions
To ensure safe operation, the device should only be operated according to the specifica -
tions in the instruction manual. The requisite Health & Safety regulations for a given
application must also be observed. This statement also applies to the use of accessories.
Every person who is commissioned with the initiation or operation of this device must have
read and understood the operating instructions and in particular the safety instructions!
The work safety instructions in this manual as well as the safety, accident prevention and
environmental protection regulations generally valid for the work area must be observed.
The liability of the manufacturer expires in the event of damage due to improper use, non-
observance of this operating manual, use of insufficiently qualified personnel and unau-
thorized modification of the device.
Proper Usage
The flow meters DV04 are designed to monitor continuous flow rates of liquids which do
not attack the device materials. All other usage is regarded as being improper and outside
the scope of the device.
In particular, applications in which shock loads occur (for example, pulsed operation)
should be discussed and checked in advance with our technical staff.
The series DV04 flow meter devices should not be deployed as the sole agents to prevent
dangerous conditions occurring in plant or machinery. Machinery and plant need to be
designed in such a manner that faulty conditions and malfunctions do not arise that could
pose a safety risk for operators.
