...Level Meter EXiaII BT4Ga Explosionproof Measuring principle The working principle of ultrasonic level meter is that the transducer (probe) sends out ultrasonic pulse, when the pulse meets the surface of the measured medium is reflected back, part of the reflected sound wave is received by the same transducer, and converted into electrical signals. The ultrasonic pulse travels at the speed of sound...

...Level Meter Distance 10 Meter To 60 Meter Principle Transmitting ultrasonic transducer emits ultrasonic pulses propagated to the measured media through communication media, through reflection and then return to the receiving transducer through the acoustic medium, the measured ultrasonic pulse propagates from the transmitter to the receiver in the acoustic medium of time. Then according to the speed of sound...
