This measuring principle is suitable for liquid, pasty, food, dirty, viscous, sticky fluids

Guided wave level transmitters offer direct and precise level measurements that are not influenced by process conditions.

Direct level measurement without the need for compensation as process conditions vary (density, conductivity, temperature and pressure).

These instruments are reliable, regardless of density, turbulence and vibration.

The absence of moving parts and any re-calibration for minimized maintenance guarantee fast commissioning.

The sensors are suitable for level measurement on liquids, even aggressive and solid at high pressure or high temperatures. In liquids they can also detect the interface between two products.

In guided wave radar sensors the measurement is not affected by density changes, foaming, steam and dust.

Adherences to the probe or to the tank walls do not compromise the measurement.

Low-emission microwave pulses of nanoseconds are guided along a submerged probe in the middle of the process.
When a microwave pulse reaches a medium with a different dielectric constant, part of the energy is reflected back to the transmitter.

The Guided Wave Radar Level Transmitter exploits the residual wave of the first reflection to measure the interface level. Part of the wave, which was not reflected by the surface of the upper product, continues until it is reflected by the surface of the lower product.
The speed of this wave depends entirely on the dielectric constant of the upper product.

Suitable for small tanks, for tanks with complex geometry and in the presence of interferences.

Installation from above to minimize the risk of leaks.
