摘要: A fill level measurement device is specified for determining distance oft he measurement device and flow speed of a medium, which comprises a frequency-modulated transmission signal having a rising and a falling frequency ramp. The flow speed of the medium can be determined by the Doppler effect arising from the flow speed of the medium.

摘要: A printed circuit board for a radar level measurement device with a printed circuit board substrate is provided, wherein a microwave signal is coupled via a microwave conductor into a waveguide. A connection region on a front side of the printed circuit board substrate serves to receive the waveguide. A shape of a resonator shell is generated inversely by producing an annular peripheral recess whose wall has an electromagnetically reflecting coating on a rear side of the printed circuit board substrate. The annular peripheral recess on the rear side, together with a region surrounded by the recess, forms a resonator for the injected microwave signals.

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.
