16.1 Application
Depending on the version ordered, the measuring device can also measure potentially
explosive, flammable, poisonous and oxidizing media.
To ensure that the device remains in proper operating condition for its service life, use the
measuring device only for media against which the process-wetted materials are
adequately resistant.
16.2 Function and system design
Measuring principle Vortex meters work on the principle of the Karman vortex street.
Measuring system The device consists of a transmitter and a sensor.
Two device versions are available:
• Compact version – transmitter and sensor form a mechanical unit.
• Remote version - transmitter and sensor are mounted in separate locations.
