Ultrasonic level measurement  Application :


Ultrasonic level measurement with Prosonic sensors provides continuous, non-contact and maintenance-free level measurement of fluids, pastes, sludges and powdery to coarse bulk materials. The measurement is unaffected by dielectric constant, density or humidity and also unaffected by build-up due to the self-cleaning effect of the sensors. Check out the broad range of Prosonic devices for ultrasonic level measurement and click on the button below.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.
