The best sensor for non-contact level monitoring of liquids and bulk solids in straightforward applications is VEGAPULS 11. It is especially well suited for use in water treatment, storage tanks with acids, lyes, and additives in all industrial settings, or for determining the level of plastic tanks from the outside via the tank wall. The sensors are utilised with bulk solids in open containers or small bulk solids silos.
The sensor emits a continuous radar signal through the antenna. The emitted signal is reflected by the medium and received as an echo by the antenna.
The frequency difference between the emitted and received signal is proportional to the distance and depends on the filling height. The determined filling height is converted into a respective output signal and output as measured value.
