The ultrasonic level sensor emits a high frequency acoustic pulse from its transducer. The pulse travels through the air gap, reflects against the liquid surface and returns to the transducer. The ultrasonic level sensor measures the pulse time of flight and converts this into level height or distance.
Applications
Ultrasonic level transmitter is installed in the upper part of the container. Under the control of the electronic unit, the probe emits a beam of ultrasonic pulses to the object under test. The measured distance is calculated according to the known sound velocity. The object value is obtained by subtraction.
The ultrasonic liquid level sensor is a very practical level measuring sensor with simple installation and convenient on-site commissioning. Not affected by the measured medium. It can measure the liquid level of various mediums with an accuracy of 0.5%. It uses SMD components and ASC chip, which makes the circuit compact and concise. The circuit board is plated and has high stability and long-term reliability. Meanwhile, the shell uses Polypropylene materials with sturdy texture and good acoustic property. The transducer can be used in most working condition sites.
