How Do Ultrasonic Level Sensors Work? |
|
Answer» An ultrasonic SOUND pulse is pulsed 4 times PER second from the base of the transducer. The pulse travels through air, reflects against the process MEDIUM below and returns to the transducer. The sensor measures the pulse time of flight between sound generation and receipt, and translated this into DISTANCE or liquid level height within the VESSEL.
