1. Wine Industry - Wine Liquid Level Monitoring: Controlling the liquid level in wine production is crucial. By installing a float level gauge in fermentation tanks or wine storage tanks, the wine liquid level can be monitored in real-time to ensure process stability and quality.

2. Dairy Production - Cream and Milk Separation Monitoring: In dairy production, it's sometimes necessary to separate cream from milk. Float level gauges can help monitor the interface between the two to ensure the accuracy and efficiency of the separation process.

3. Juice Production - Concentration Control: Controlling the concentration of juice is essential to maintain product taste and quality. Float level gauges can be used to monitor the interface between juice and water, allowing adjustments to be made during the concentration process.

4. Edible Oil Processing - Oil-Water Separation: In edible oil processing, separating oil from water is necessary. Float level gauges can monitor the position of the oil-water interface, facilitating timely separation of pure edible oil.

5. Canning Process - Filling Control: In canned food processing, ensuring consistent food quantity in each container is vital. Float level gauges can monitor the food level inside cans in real-time, enabling precise control of filling volumes.

These application examples demonstrate the diverse uses of float level/interface gauges in the food processing industry, helping to improve production efficiency, ensure product quality, and promote automation and digitization of production processes.
