Taking guided wave radar benefits to the next level

Measurement principle

Low power, nano-second microwave pulses are guided down a

probe submerged in the process media. When a microwave

pulse reaches a media with a different dielectric constant, part

of the energy is reflected back to the transmitter.

The transmitter uses the residual wave of the first reflection for

measuring the interface level. Part of the wave, which was not

reflected at the upper product surface, continues until it is

reflected at the lower product surface. The speed of this wave

depends fully on the dielectric constant of the upper product.

The time difference between the transmitted and the reflected

pulse is converted into a distance, and the total level or interface

level is then calculated. The reflection intensity depends on the

dielectric constant of the product. The higher the dielectric

constant value, the stronger the reflection is.

Guided wave radar technology

benefits

 Highly accurate and reliable direct level measurement with no

compensation needed for changing process conditions (such

as density, conductivity, viscosity, pH, temperature, and

pressure)

 No moving parts and no re-calibration result in minimized

maintenance

 Handles vapor, dust, turbulence, and foam well

 Suitable for small tanks, difficult tank geometry, internal

obstacles, and unaffected by the mechanical design of

chambers

 Top down installation minimizes risk for leakages
