To ensure safe operation, the device should only be operated according to the
specifications 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 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
unauthorized modification of the device.
Proper Usage
The ultrasonic flow meter Du06 are designed to measure the flow 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 DU06 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.
Dangerous substances
For dangerous media such as e.g. Oxygen, Acetylene, flammable or toxic substances as
well as refrigeration systems, compressors, etc. must comply with the relevant regulations
beyond the general rules.
