Guided Wave Radar Level Sensors and Products

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 advantages are the TDR sensors measure reliably despite:

  • steam
  • pressure and temperature fluctuations
  • dust and noise
  • buildup and condensation

Honeywell SmartLine Guided Wave Radar

Description & Features

SmartLine Level Transmitter uses guided wave radar (GWR) technology and can measure the level of a wide range of liquid products on a large variety of installations within the stated pressure and temperature range. It can be deployed at blending tanks, distillation columns, process tanks, separators, solid silos (inventory) and storage tanks. It does not require calibration or commissioning upon installation, and can measure liquid interface with or without an air gap.

Additionally, the level meter can measure the level and interface simultaneously, and is capable of measuring media with a dielectric constant of 1.4 or greater. A variety of rigid and flexible probes allow measurement in silos and tanks up to 50 m (164 ft) high.
