Ultrasonic level measurement
In non-contact ultrasonic level measurement, the sensor emits ultrasonic pulses in the direction of the medium, which then reflects them back.
The elapsed time from emission to reception of the signals is proportional to the level in the tank. Level sensors based on this measuring principle are ideal for simple standard applications, both for liquids and for solids.
The advantages
Non-contact ultrasonic sensors operate independently of product properties and even penetrate dusty atmospheres.
Measuring principle
Short ultrasonic impulses in to range of 10 to 70 kHz are emitted by the transducer to the measured product, reflected by the product surface and received again by the transducer. They spread with sound velocity. The time from emission to reception of the signals is proportional to the level in the vessel. The proven ECHOFOX signal processing filters out the correct level echo reliably from a number of false reflections. An adjustment with empty and full vessel is not necessary!
