Description

Technical Field

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

[0002] Ultrasonic level meter is a digital level meter controlled by a microprocessor. During measurement, ultrasonic pulses are emitted by (transducer), and the sound waves are received by the same sensor after being reflected by the liquid surface, and converted into electrical signals by piezoelectric crystals. The distance from the sensor to the surface of the measured liquid is calculated by the time between the emission and reception of the sound waves. Due to the use of non-contact measurement, the measured medium is almost unlimited, and it can be widely used to measure the height of various liquids and solid materials.

[0003] After installation, the meter head of the existing ultrasonic level meter protrudes beyond the detection equipment, which makes the meter head vulnerable to collision during use. At the same time, the root of the connecting wire is prone to breakage when bent or subjected to external force, thus affecting the normal use of the ultrasonic level meter. In order to solve the above problems, a protective structure of an ultrasonic level meter is proposed in this application. Utility Model Content
