Anti corrosive ultrasonic fluid level sensor
Anti corrosive ultrasonic fluid level sensor
Principle
The operating principle of ultrasonic level sensor is that high-frequency ultrasound pulses transmitted by the transducer (probe) are reflected when meeting the dielectric surface to be measured, and part of the reflected echoes are received by the same transducer and converted into electrical signals. An ultrasonic pulse propagates at the speed of sound, and the time interval of transmitting and receving ultrasound pulses is proportional to the distance between the transducer and the dielectric surface to be measured. The relation between this distance value S, the speed of sound C and the transmission time T can be expressed using the formula: S=CxT/2.
The transmitted ultrasonic pulses have a certain width that result in overlap of the reflected waves within a small area closer to the transducer with the transmitted waves, so it is impossible to identify them and measure its distance value. This area is called the blind zone. The size of blind zone is relates to the model of ultrasonic level instrument.
