2.1 Safe operation
This device is built based on current state-of-the-art technology and is safe to use. The device has been
tested and was shipped from the plant in perfect working order.
If you do not follow the measures to ensure safe operation, this may result in risk to life and damage to
property due to improper use.
• Only ever use the device for its intended purpose.
• Do not place the device and the process connections under mechanical strain.
• Systematically check that the process connections are leak-tight.
• Protect the device from electromechanical interference and UV radiation.
• Protect the device from the weather (when using outside).
• Only perform modifications and repairs to the device if expressly permitted by the documentation.
2.2 Intended use
The ultrasonic flowmeter measures the flow, temperature and optionally the pressure of conductive and
non-conductive liquid media.
The process values can be mapped via the process display, and issued to a higher-level system via the
outputs.
During operation, the admissible data and operating conditions specified in the legal documents and op-
erating manual must be observed.
2.3 Qualification of personnel
The personnel deployed must meet the following requirements in all phases of the product lifecycle:
• Trained electrical, mechanical, and plant engineering personnel.
• Members of personnel are familiar with this documentation and the safety information and warnings
it contains.
2.4 Hot media
Hot media may result in the device surfaces becoming hot and presenting a risk of injury.
• Allow the device and plant to cool down.
• Wear suitable protective equipment.
• Take into account alignment of the housing for electronic components.
"Alignment of the housing for electronic components", Page 21
• If required, install contact protection.
Usage Suitable Not suitable
Continuous measurement of the volume flow x
Conductive and non-conductive media x
Potentially explosive areas and safety applications x

2.5 Hazardous materials
Using hazardous materials as a medium may result in abrasive and corrosive damage to components
of the product that come into contact with the medium. The medium may leak and present a fire hazard
and a risk to health.
Carry out a risk assessment taking into consideration the safety data sheet for the relevant hazardous
substance for mounting, operation, maintenance, cleaning, and disposal:
• Comparison and systematic checking of the durability of the components of the product that come
into contact with the medium and the admissible environmental influences.
• Assessment of the risk to people and the environment.
• Assessment of the fire hazard due to the product materials, the admissible environmental influences,
and the voltage supply.

3.1 Design
3.2 Function
The transducers are on opposite sides of the measuring section and act as transmitters and receivers,
i.e. they convert the electrical energy into sound waves and the sound waves into electrical energy.
The electronic components supply power to the device, convert the raw signals into standard signals for
communicating with other systems (PLC, recorder, indicating device, etc.), and provide interfaces for dis-
playing measured values.

The ultrasonic flowmeter works
according to the runtime method.
This method measures the run-
times t1 and t2 required by the
sound to travel from transducer A
to transducer B and vice versa.

5.1 Scope of delivery
5.2 Checking the delivery
• Ensure that the packaging and its contents are undamaged.
• Check the delivery for completeness against the packing slip and order details.
• Inform the supplier immediately if there is any damage.
• Store damaged parts until clarification is received from the supplier.
5.3 Storage
Improper storage may result in damage to the device.
• Store the device in a dry and dust-free environment.
• Observe the device storage temperature range.
5.4 Packaging and transport
If the device is not protected properly against external influences, it may become damaged during trans-
port.
• Transport the device in an impact-proof packaging solution that protects it against moisture and dirt.
• Also comply with the admissible storage temperatures while the device is being transported.
• Protect all electrical and mechanical connections from damage.

6 Installation
6 Installation
6.1 Prepare installation
Requirements:
• Check the environmental influences to which the device will be exposed.
• De-energize the system and secure it against being switched on again.
• Stop medium circulation in the plant.
• Drain and flush the pipe.
• Wear suitable protective equipment.
• Correctly prepare the pipe for installation.
• Use only suitable tools when working on the device and plant.
Inlet and outlet sections
Installation position
To calm the flow in the pipeline,
the specified inlet and outlet sec-
tions are required at the very
least.
For increased accuracy, the inlet
and outlet sections can be made
longer.

Mount the device in either the hor-
izontal or vertical pipe.
Requirements:
• The pipe around the transduc-
ers must be filled.
• The flow direction should be
upwards for vertical mounting.
• Avoid the formation of air bub-
bles in the pipe and right at
the device.
