Ultrasonic Level Sensor

Ultrasonic level sensors provide a reliable and maintenance-free way to measure liquid and solid levels without direct contact with the process medium. Using sound wave reflection technology, they determine the distance between the sensor and material surface with exceptional accuracy even in challenging environments.

How Ultrasonic Level Sensors Work

Ultrasonic sensors operate by emitting high-frequency sound waves toward the surface of the material being measured. The sensor calculates level based on the time it takes for the echo to return after hitting the surface.

Because measurement depends on time-of-flight rather than electrical or mechanical properties, ultrasonic level sensors provide stable readings regardless of medium composition, conductivity, or density.

This non-contact principle makes them ideal for liquids, slurries, and light bulk solids, offering a perfect balance of precision and simplicity for a wide range of industrial applications.

Frequently Asked Questions (FAQs)

What is an ultrasonic level sensor used for?

It measures the level of liquids or solids by sending ultrasonic waves and calculating the echo time for accurate, non-contact level monitoring.

Can ultrasonic level sensors measure solids as well as liquids?

Yes, they can measure bulk solids like grains, powders, and pellets, provided the surface reflects ultrasonic waves effectively.

How do ultrasonic level sensors handle foam or vapor?

VEGASON sensors use intelligent signal processing and echo suppression to provide stable readings even with foam or vapor presence.

Are ultrasonic sensors affected by temperature?

Integrated temperature compensation ensures consistent accuracy despite temperature variations.
