 Level 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.

- Replaces switches, displacers, ultrasonic meters and pressure transmitters.
- Low cabling costs.
- High accuracy and repeatability.
