Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic level meters, in particular to an ultrasonic level meter with a waterproof function. Background Art

[0002] The working principle of the ultrasonic level meter is that the transducer sends out ultrasonic pulses, which are reflected back when encountering the surface of the measured medium. Part of the reflected echo is received by the transducer and converted into an electrical signal through a piezoelectric crystal or a magnetostrictive device. The distance from the sensor to the surface of the measured object is calculated by the time between the emission and reception of the sound wave. Due to the use of non-contact measurement, the measured medium is almost unrestricted and can be widely used to measure the height of various liquids and solid materials.

[0003] The existing ultrasonic level meter can be used to measure the height of liquid or solid materials. When measuring the depth of the liquid, the ultrasonic level meter is usually placed inside the liquid to measure its depth. However, since the existing ultrasonic level meter does not have a waterproof function, if the ultrasonic level meter is used to measure the liquid, the liquid may penetrate into the inside of the ultrasonic level meter, causing damage to the ultrasonic level meter and affecting the use effect of the ultrasonic level meter. For this reason, we propose an ultrasonic level meter with a waterproof function. Utility Model Content
