In level measurement with guided wave radar, microwave pulses are conducted along a cable or rod probe and reflected by the product surface. The measuring probe of the TDR sensor ensures that the signal reaches the medium undisturbed. Liquids, bulk solids and separation layers (interfaces) in liquids are commonly measured with this measuring technique.
The TDR sensors measure reliably despite:
- Steam
- Pressure and temperature fluctuations
- Dust and noise
- Buildup and condensation
