Instruments:
 FMCW-Radar
uses a high-frequency signal (~10 GHz) which increases in frequency
linearity during the measurement (frequency sweep). The signal is
emitted, reflected on the measuring surface and received
time-delayed. For further signal processing the difference? Is
calculated from the actual transmit frequency and the receive
frequency. The difference is directly proportional to the distance
i.e. a large frequency difference corresponds to a large distance
and vice versa. This frequency difference is converted into a
frequency spectrum using a Fourier transformation (FFT) and yields
the distance to the surface. The level in turn is the difference
between surface and previously determined empty tank distance.
Highlights:
- Replaces switches, displacers, ultrasonic meters and
pressure transmitters.
- Low cabling costs.
- High accuracy and repeatability.
