  • contactless measurement of the level of various fluids and of media interface distance in one or two measurement channels;
  • automatic accounting for ultrasound velocity alteration upon alteration of gas medium parameters;
  • minimum influence of surface foam on measurement results;
  • transducer periodic self-cleaning from condensate and fouling;
  • transmitter can be placed at a distance of up to 250 m from the measurement site;
  • high-temperature sensors (0 ÷ 100°С) available;
