Measurement principle
The product employs frequency-modulated continuous-wave (FMCW) technology, transmitting a high‑frequency, continuously frequency‑modulated radar signal via its antenna. This transmitted signal is reflected by the medium and received by the antenna as an echo with a shifted frequency. The frequency shift is proportional to the distance and is converted into a level measurement.
Non-contact measurement is employed to determine the level of both liquid and solid media. Even under high pressure and extreme temperatures, these sensors can reliably measure a wide range of liquid media—such as solvents, corrosive substances, and hygienic applications. Moreover, they provide stable and dependable measurements for both light and heavy solids; even in the presence of intense dust and noise, or under conditions of adhesion and condensation, measurement performance remains unaffected.
◆ Key Features
▶ Non-contact measurement, unaffected by changes in medium properties (temperature, pressure, dust);
▶ Simple setup and fast boot time;
▶ Essentially maintenance-free;
▶ Wide measurement range, small blind zone;
▶ The antenna is compact, with a narrow beamwidth and strong focusing capability.
▶ It can be used in vessels equipped with agitators, heating coils, baffles, or in straight pipes.
▶ High measurement accuracy;
▶ Radar waves have short wavelengths, making them highly effective for level measurement of powders, granules, and similar materials.
▶ No universal flange is required to aim at the target;
▶ A lens antenna is employed.
◆ Application scenarios
It can adapt to a wide range of complex measurement conditions. For example: high dust levels and long measurement ranges in the cement, power, and coal industries; high temperature, high pressure, high precision, strong corrosivity, and high viscosity in the petrochemical industry; small vessel sizes, short measurement ranges, and limited blind zones in the metallurgical industry; and cleanliness and hygiene requirements in the food and pharmaceutical industries—covering numerous sectors and operating environments.
