18.1
Application
The measuring device is suitable for flow measurement of liquids and gases only. Depending on the
version ordered, the measuring device can also measure potentially explosive, flammable, poisonous
and oxidizing fluids.
To ensure that the device remains in proper operating condition for its service life, use the measuring
device only for fluids against which the process-wetted materials are adequately resistant.
18.2
Function and system design
Mass flow measurement based on the Coriolis measuring principle
The device consists of a transmitter and a sensor. One device version is available:
Compact version: transmitter and sensor form a mechanical unit.
