Radar Level Measurement

Radar Level Measurement

Free-space radar level measurement provides non-contact continuous level measurement using high-frequency radar pulses emitted from an antenna. It is broadly applied across industries due to its measurement stability and low maintenance profile.

The instrument transmits radar pulses, which reflect from the product surface due to a change in relative dielectric constant. Time-of-flight is measured and converted to distance, and level is calculated from known tank geometry. Antenna selection and signal processing determine performance in challenging vessels.

A central advantage is that measurement is non-contact and maintenance-free. The method is generally unaffected by medium properties such as density and conductivity, and in bulk solids it can remain stable despite filling noise and dust. Free-space radar can also be applied in demanding temperature and pressure environments.

Typical applications include storage tanks, corrosive or aggressive chemical services, hygienic vessels, and high-accuracy tank gauging scenarios where inventory visibility and repeatability matter. Antenna variants support different process connections and installation constraints, enabling application fit across both liquids and solids.

Engineering work typically addresses nozzle and stilling well effects, internal obstructions, foaming or condensing vapors, and dielectric limitations for very low-permittivity products. Proper antenna choice, mounting orientation, and configuration of the measurement range are the primary levers for maximizing echo quality and minimizing false reflections in complex vessels.
