Determining a Level and Flow Speed of a Medium

摘要

A measurement device is provided for determining a distance of the measurement device from a medium and a flow speed of a medium by evaluating a transmission signal emitted by the fill level measurement device and reflected by the medium. The measurement device includes an antenna arrangement for emitting the transmission signal in two different directions. The flow speed of the medium can be determined using the Doppler shift of the transmission signal.
