YK-RLEA

Integral Ultrasonic Level Meter

The working principle of ultrasonic level measurement relies on the constant speed of sound in air: the meter emits a sound wave and starts timing; upon receiving the echo reflected from the material surface, it stops timing. Since the measured time corresponds to the round-trip travel, the actual distance is half the total path. Given a fixed tank or pool height, the level is calculated as the total height minus this measured distance, enabling non-contact, continuous level monitoring for both liquids and solids.
