Advantages and Applications of Hygienic Flow Meters

In industries such as food processing and pharmaceuticals, where strict hygiene standards are essential, accurate and reliable flow measurement is crucial to ensuring product quality and production safety. ARTang’s hygienic flow meter, with its outstanding performance and wide range of applications, has become the preferred choice for many companies. This article explores in depth the advantages and applications of ARTang’s sanitary-grade electromagnetic flow meter.

Advantages of Hygienic Flow Meters

1. Sanitary Design that Meets Industry Standards

The hygienic flow meter is specifically engineered to meet the stringent hygiene requirements of the food industry. It adopts sanitary-grade lining materials and clamp connection processing technology. This design not only ensures that the measuring medium remains uncontaminated during operation but also effectively prevents the accumulation of residual substances inside the measuring tube. In addition, the flow meter features a stainless steel housing and clamp connections, allowing for quick disassembly and easy cleaning—further enhancing its sanitary performance.

2. High Measurement Accuracy Ensures Product Quality

The food-grade electromagnetic flow meter operates based on Faraday’s law of electromagnetic induction. It calculates flow by measuring the induced voltage generated when a conductive liquid passes through a magnetic field. This measurement method is unaffected by changes in fluid density, viscosity, temperature, pressure, or conductivity, ensuring high accuracy. In food processing applications, precise flow measurement guarantees accurate ingredient ratios, thereby maintaining product quality and consistency in taste.

3. No Pressure Loss Design Reduces Energy Consumption

Compared with traditional flow measurement instruments, the hygienic flow meter features a smooth measuring tube with no obstructive components inside, which means it does not cause any pressure loss. This no-pressure-loss design not only reduces energy consumption but also minimizes wear on internal measuring parts, extending the overall service life of the equipment.

4. Intelligent Communication for Remote Monitoring

The hygienic flow meter supports multiple communication protocols, including HART, PROFIBUS DP/PA, FOUNDATION Fieldbus (FF), and MODBUS RS485. These communication options enable seamless integration with various process control systems, allowing for remote monitoring and data analysis. Through remote monitoring, operators can access real-time flow data, make timely adjustments to production parameters, and improve overall operational efficiency.

5. Easy Installation and Maintenance, Lower Operating Costs

The food-grade electromagnetic flow meter is designed for simple installation and maintenance. Its straightforward and robust structure, with no moving parts, makes setup and commissioning hassle-free. In addition, the flow meter features a self-diagnosis function that allows online verification of measurement accuracy without interrupting the process, significantly reducing maintenance and operating costs.

Core Advantages of the ARTang Hygienic Flow Meter

High Sanitary Standards:

The measuring tube, electrodes, and lining are all made from food-grade materials with a polished surface finish (Ra ≤ 0.8μm). The meter also meets international hygiene certifications such as 3-A, EHEDG, or FDA, ensuring full compliance with food industry sanitation requirements.

Cleaning Compatibility:

Supports CIP/SIP processes. The measuring tube materials are resistant to high temperatures up to 140°C and alkaline cleaning agents. Additionally, surface treatments such as electrolytic polishing further improve cleaning efficiency.

Lining Material:

PTFE or PFA are the preferred lining materials. Their surface roughness (Ra < 0.4μm) prevents microbial adhesion and withstands high-temperature steam sterilization during CIP processes at up to 140°C.

Bidirectional Measurement Capability:

The flow meter can measure both forward and reverse flow, meeting the process requirements of breweries and other facilities where reverse flushing occurs during CIP (Clean-in-Place) operations.

Dead Zone–Free Design:

The interior of the measuring tube is smooth and free of protrusions to eliminate fluid residue. For example, hygienic clamp connections replace traditional threaded joints, and EPDM seals ensure completely dead-zone-free cleaning.

Sealing Materials:

Food-grade materials such as silicone rubber or fluororubber are used for seals to ensure reliable and sanitary sealing performance.

Applications of Food-Grade Electromagnetic Flow Meters

1. Food Processing Industry

In the food processing industry, hygienic flow meters are widely used for measuring the flow of various liquid food products such as milk, juice, beer, soy sauce, and more. With their high measurement accuracy and sanitary design, these flow meters meet the strict hygiene and performance standards required in food production, ensuring product quality and safety.

2. Pharmaceutical Industry

The pharmaceutical industry also demands high precision and stringent hygiene standards for flow measurement. Food-grade electromagnetic flow meters can accurately measure a wide range of liquid flows in pharmaceutical processes, including suspensions, pharmaceutical solutions, and vaccines. Their reliable performance and easy-to-clean design make them a preferred choice in pharmaceutical manufacturing environments.

3. Beverage Industry

In the beverage industry, food-grade electromagnetic flow meters are used to measure the flow of various beverages such as carbonated drinks, fruit juices, and tea-based beverages. With high measurement accuracy and fast response speed, these flow meters provide precise flow data that support reliable mixing and filling operations throughout the production process.

4. Dairy Industry

The dairy industry demands exceptional accuracy and strict hygiene standards for flow measurement. Hygienic flow meters can accurately measure the flow of dairy products such as milk and cream, ensuring precise ingredient ratios and consistent quality control during production. Their sanitary design also meets the dairy industry’s rigorous requirements for equipment cleanliness and hygiene.

With its sanitary design, high measurement accuracy, no-pressure-loss structure, intelligent communication capabilities, and ease of installation and maintenance, the hygienic flow meter plays a vital role in industries such as food processing, pharmaceuticals, beverages, and dairy products. As industrial automation continues to advance, food-grade electromagnetic flow meters will keep providing these industries with reliable and precise flow measurement solutions, driving continuous improvement and sustainable development across the sector.
