2.1 Intended use
The device is intended for measuring the flow and temperature of liquid media having a minimum con-
ductivity of 20 μS/cm and a maximum viscosity of 70 mPa·s.
In order to ensure the device's perfect condition, only media may be used to which the materials in con-
tact with the media are sufficiently resistant.
The operator is responsible for compliance with the specifications indicated in the technical data (e.g.
operating and ambient temperature).
The device may only be used in a technically perfect condition, in accordance with its intended use, in a
safety-conscious and hazard-conscious manner and in compliance with the operating manual.
The following in particular are considered to be improper
• Any structural, technical or electrical modifications to the device.
• Use of the device outside the areas described in this operating manual.
• Use of the device deviating from the technical data.
The manufacturer is not liable for any damage resulting from improper use.
2.2 Qualification of personnel
The personnel deployed must meet the following requirements in all phases of the product lifecycle:
• Members of personnel have at least completed training in the field of plant mechanical systems for
sanitary, heating, and air-conditioning technology or have completed a degree in electrical engineer-
ing or mechanical and plant engineering.
• Members of personnel are familiar with this documentation and the safety information and warnings
it contains.
2.3 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.
• If required, install contact protection.
• Take into account alignment of the housing for electronic components.

2.4 Hazardous materials
Using hazardous materials as a medium may result in abrasive and corrosive damage to components
of the device 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 device 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 device materials, the admissible environmental influences,
and the voltage supply.
2.5 Mechanical load
Mechanical load on the device and process connections can lead to leaks.
• Do not place the device and the process connections under mechanical strain.
• Systematically check that the process connections are leak-tight.

3.1 Scope of delivery
3.2 Structure
3.3 Function
The device records the flow according to the principle of electromagnetic flow measurement. This prin-
ciple is based on Faraday's law of induction.
An electrically conductive liquid flows through a measuring pipe. A magnetic field is generated in the
measuring pipe perpendicular to the flow direction. The magnetic field is created by current flowing
through a pair of field coils.
The magnetic field induces a voltage in the liquid. Two electrodes are located opposite each other on the
measuring pipe. The electrodes pick up the generated voltage and transmit the measurement results to
the integrated evaluation electronics.
