Flow measurement challenges under stringent standards in the food industry

Under the stringent hygiene standards of the food industry, Magne electromagnetic flowmeters stand out due to their high-precision measurement and pollution-free characteristics. Real-world test data shows that the HY-LD and ZK-LDE series maintain a 0.5-level accuracy even in viscous liquids and corrosive media, making them the preferred solution for leading companies such as Yili and Mengniu. This article will provide an in-depth analysis of how its 316L stainless steel electrodes and PTFE lining meet FDA certification requirements.

Core Technology Analysis: Hygienic Design from Electrodes to Lining

Magne electromagnetic flow meters use FDA-certified PTFE lining material with a surface roughness Ra≤0.8μm, far below the critical value of 1.6μm for microbial adhesion. Taking the ZK-LDC electromagnetic flow meter as an example, its 316L electrode undergoes electrolytic polishing and, combined with an IP68 protection rating, can withstand CIP (in-situ cleaning) high-temperature strong acid and alkali erosion. Test data shows that when measuring high-viscosity media such as yogurt, the repeatability error of the W3000 PLUS electromagnetic flow meter is stable within ±0.2%, a performance indicator that is difficult for mechanical flow meters to achieve.

Procurement Guide: Five Key Parameters Determine Product Selection

Technical assessors should focus on: 1) the DN15-DN600 diameter coverage of the TC-ZNDC electromagnetic flowmeter; 2) the standard 4-20mA+HART protocol output of the MGG electromagnetic flowmeter; 3) the wear-resistant design of the HK-LDE electromagnetic flowmeter in media containing particulate matter; 4) the ≤1ms response time of the LDG electromagnetic flowmeter; and 5) the clamp connection method of the TC-DCGD electromagnetic flowmeter, which is certified by the 3-A Sanitary standard. Xi'an Shenghongchuang Instrument Co., Ltd. provides customized solutions that can match the optimal lining material according to the temperature difference (-30℃~180℃) of different process stages such as pasteurization and fermentation.

In-depth analysis of industry certification and compliance

In addition to FDA approval, the Magne series products also meet EHEDG, GMP, and ISO 2852 standards. Particularly in the aseptic filling process, the ZK-LDE electromagnetic flowmeter's 3D velocity profile compensation technology can control measurement deviations caused by bubble interference to below 0.1%. As a high-tech enterprise in Xi'an New Area, our laboratory can provide third-party validation reports, including a complete set of documents such as EMC immunity testing and material leachate detection.
