Description

Technical Field

[0001] The utility model relates to the technical field of liquid level sensors, in particular to a non-contact liquid level sensor that is convenient for pipeline installation. Background Art

[0002] As an advanced liquid level monitoring technology, the working principle of non-contact liquid level sensor is based on the propagation characteristics of sound waves, microwaves, lasers or other electromagnetic waves. Compared with traditional contact sensors, non-contact liquid level sensors do not need to be in direct contact with the measured medium, thus avoiding problems such as corrosion, pollution and wear, and greatly improving the service life and measurement accuracy of the sensor. In addition, non-contact liquid level sensors also have the advantages of easy installation, convenient maintenance and strong adaptability. They can be widely used in many industries such as petrochemicals, water treatment, food and beverages, and pharmaceuticals. As a type of non-contact liquid level sensor, the pipe clamp type pipeline dedicated non-contact liquid level sensor has a unique design that makes it particularly suitable for liquid level monitoring of pipeline systems. The sensor adopts a pipe clamp structure and can be easily installed on the pipeline to achieve real-time monitoring of the liquid level in the pipeline.

[0003] A Chinese patent with publication number CN218035238U discloses a pipeline liquid level sensor, which includes a shell, a main control chip and a tube body snap-fitted at one end of the shell, two right-angle blocks made of transparent material are provided on the tube body, a light-emitting component is provided on one side of one right-angle block, and a photosensitive component is provided on one side of the other right-angle block, an angle is formed between the light-emitting component and the photosensitive component, the main control chip is electrically connected to the light-emitting component and the photosensitive component, and is used to detect the liquid level in the pipeline, the shell includes a front shell and a rear shell, a fixing portion for fixing the tube body is provided at one end of the shell, the main control chip is installed in the front shell, a second empty slot and a third empty slot are opened on one side of the main control chip, the light-emitting component is installed in the second empty slot, the photosensitive component is installed in the third empty slot, and the main control chip is electrically connected to the light-emitting component and the photosensitive component.

[0004] At present, we have found that there are still some shortcomings in the actual application of the pipe clamp type pipeline non-contact liquid level sensor in the existing technology on the market. For example, the traditional pipe clamp type pipeline non-contact liquid level sensor is installed in the pipeline mainly by using the integrated pipe clamp on the non-contact liquid level sensor, which is directly buckled on the pipeline and is convenient to adjust. However, due to its integrated structure, when replacing different pipelines for installation or when the pipe clamp is broken or damaged, the entire non-contact liquid level sensor must be replaced together, which is relatively wasteful.
