Ultrasonic level sensors

Ultrasonic signal is a mechanical wave, like sound waves. An ultrasonic signal emitted by an instrument is reflected off the product surface which will be received again by the instrument. The instrument is working on the Time of Flight method. Ultrasonic Instruments are used in fluids, pastes, coarse bulk material, and flow measurement in open channels or at weirs.
