The ultrasonic distance sensor, ultrasonic echo principle, using the precise time difference measurement technique, between the sensor and the target distance, using small angle factory development, the small blind ultrasonic sensor has the advantages of accurate measurement, non-contact, waterproof, anti-corrosion, low cost and other advantages, it can be used for liquid level,. Position detection, characteristic level, material level detection method, can ensure that there is a bubble or a large rock on the surface, not easy to detect echo in the case of stable output.
