Ultrasonic Level Sensor


Ultrasonic Level Sensor is suitable for continuous level measurement of liquids and bulk solids. The measurement is unaffected by dielectric constant, density or humidity. The ultrasonic method is a proved, as well as cost-effective solution for level measurement in liquids and bulk solids. Instruments are available as compact or separate versions. This measuring principle is characterized by easy planning and assembly, fast and safe commissioning, a long service life and reduced maintenance costs. Typical applications include abrasive and aggressive media, even in rough ambient conditions.

Typical applications of ultrasonic level sensor are the measurement of liquids in storage vessels or open basins. The sensor can be used for detection of bulk solids in small vessels or silos. Application areas can be found in all industries.

  • Measurement unaffected by media properties, like dc value or density
  • Price-favourable solution for simple applications
  • Maintenance-free operation through non-contact measuring principle
  • Reliable measurement independent of product features
  • Calibration without filling or discharging
