Ultrasonic is a contact-less technology for level measurement applications. The sensor emits short ultrasonic pulses which are reflected from the product surface and captured by the same sensor. The distance to the product surface is obtained with the exact measurement of the time between pulse emission and echo reception, and consequently the level measurement. An internal digital temperature sensor corrects the measurement as a function of air temperature. Our ultrasonic level transmitters are suitable for measurements of liquids and granules, for distance up to 12 m. Concentrated acids, toxic waste, vapors, agitators presence, by-pass pipes are not obstacles to their application thanks to an evolved signal processing system and a sophisticated analysis of the received echo.
