FAQ

A guided wave radar level sensor is a sensor that measures liquid or material level by transmitting and reflecting high-frequency microwaves along a probe or cable. It calculates the level by measuring the time it takes for the pulse to travel from emission to reflection.

They are suitable for liquids, slurries, and some solid powders. They operate stably, especially in high-temperature, high-pressure, or corrosive environments, such as in the chemical, petrochemical, water treatment, and food processing industries.

Guided wave radar transmits signals through a probe or cable, while non-contact radar transmits signals directly through the air. Guided wave radar is more suitable for confined spaces and environments with high levels of steam or foam, providing more stable measurement results.
