Liquid Level Detector

Liquid Level Detector is a level detection instrument developed and produced by our company, reaching advanced domestic and international standards. Utilizing low-energy photon sources and the interaction between the detected material and the photon, the ray intensity changes with the material's position, allowing control of the filling liquid material's capacity. Due to its non-contact measurement method, it fundamentally solves the problem of measuring the liquid capacity in filling lines, which is difficult for conventional weighing methods. Therefore, it is widely applied in the automatic online control of filling liquid materials in production lines for food, pharmaceuticals, chemicals, etc. (whether bottled or canned).

Design Basis

In the beverage packaging process, due to the stability of production equipment and the skill level of operators, each packaging step on the production line may have different packaging quality defects. These defects lead to various defective products, affecting product quality. Specific issues include:

Currently, most production enterprises use manual inspection or weighing to control the above risks, but manual inspection or weighing has significant limitations, as shown below:

As seen above, using traditional manual inspection or weighing methods for various quality defects in the production line cannot achieve ideal detection results or effectively control production risks.

Solution

Based on the beverage production process for cans, the solution is to install automatic detection equipment at appropriate positions on the production line, enabling automatic online detection of each product and automatic rejection of defective items. The equipment installed is as follows:

By installing automated detection equipment, quality control is realized across each packaging step, with defects being removed in real-time. In case of production faults, a complete alarm system promptly notifies on-site personnel to handle the issue, ensuring production efficiency.

Advantages of Installing Online Detectors

These advantages are not only beneficial for the detection itself but also highlight the importance of advanced automated equipment in future smart factories. For example, providing industrial Ethernet interfaces for upper-level systems and offering various communication support for other devices, enabling future automation and networking upgrades.
