The 5H2B Electromagnetic Flowmeter, a high-performance flow measurement device belonging to Endress+Hauser’s Proline Promag H200 series, is specifically engineered to deliver accurate, reliable, and stable flow rate measurement for conductive liquids in various industrial scenarios. As a professional electromagnetic flowmeter, it adopts advanced electromagnetic induction technology, combined with rigorous manufacturing standards and intelligent design, making it an indispensable measurement tool in industries such as chemical engineering, water treatment, food and beverage, pharmaceuticals, and petrochemicals.
Based on Faraday’s Law of Electromagnetic Induction, the 5H2B flowmeter operates by generating a stable magnetic field through internal excitation coils. When conductive liquid flows through the non-magnetic measuring tube, it cuts the magnetic field lines, inducing an electromotive force (voltage) that is directly proportional to the flow velocity of the liquid. This induced voltage is captured by high-sensitivity electrodes, then processed and converted by the built-in intelligent transmitter into standard electrical signals (4-20mA DC, HART, Modbus, PROFIBUS, etc.) that can be easily integrated with industrial control systems, enabling real-time monitoring and remote control of the flow process.
One of the core advantages of the 5H2B Electromagnetic Flowmeter is its high measurement accuracy and strong anti-interference capability. With an accuracy of ±0.5% of reading ±2 mm/s (0.08 in/s) for volume flow, it can maintain stable measurement performance even in complex industrial environments with voltage fluctuations, electromagnetic interference, or changes in medium properties. Unlike traditional mechanical flowmeters, it has no moving parts inside the measuring tube, which eliminates the risk of wear, clogging, or leakage, greatly reducing maintenance costs and extending the service life of the equipment. The measurement process is not affected by changes in medium pressure, density, temperature, or viscosity, ensuring consistent and reliable data output for critical industrial processes.
In terms of structural design, the 5H2B flowmeter features a compact and robust structure, with a focus on practicality and adaptability. The measuring tube is lined with high-quality PFA material, which has excellent chemical resistance, corrosion resistance, and hygiene performance, making it suitable for measuring corrosive liquids (such as acids, alkalis, and solvents) and high-purity liquids (such as ultra-pure water in pharmaceutical industry). The electrode materials are available in multiple options, including 1.4435 (316L) stainless steel, Alloy C22 (Hastelloy C22), Tantalum, and Platinum, allowing users to choose the most suitable configuration according to the characteristics of the measured medium. The process connections are available in stainless steel (1.4404/F316L), PVDF, and PVC adhesive sleeves, compatible with various pipeline specifications and installation methods, including flange, sanitary, and threaded connections, meeting the diverse installation needs of different industrial sites.
The 5H2B flowmeter is equipped with a loop-powered design, which operates solely on the 4-20mA signal loop without the need for an external power supply, reducing wiring costs and simplifying system integration. It also features Heartbeat Technology, a unique self-diagnosis and verification function that continuously monitors the operational status of the flowmeter, timely detects potential faults, and provides real-time alerts, ensuring process safety and reducing unplanned downtime. The user-friendly operation design includes a backlit LCD display with touch control, allowing for convenient parameter configuration and data reading without opening the device cover. For remote operation needs, optional WLAN access is available, enabling users to perform parameterization, diagnostics, and data monitoring through mobile devices, improving operational efficiency.
In terms of environmental adaptability, the 5H2B flowmeter has an ingress protection rating of IP69K, which is dust-tight and resistant to high-pressure washdown, making it suitable for harsh industrial environments such as outdoor installations, high-humidity areas, and places requiring regular cleaning (such as food and beverage factories). It can operate stably within a medium temperature range of -20°C to +150°C (-4°F to +302°F) and a maximum process pressure of PN 40, Class 150, 20K, adapting to various extreme working conditions.
The 5H2B Electromagnetic Flowmeter has obtained multiple international certifications, including SIL 2/3, Ex ia (intrinsically safe), 3-A, EHEDG, and GMP, meeting the strict quality and safety standards of different industries. It is widely applied in various fields: in the chemical industry, it is used for measuring corrosive liquids, solvents, and small-flow chemical dosing; in the pharmaceutical and life sciences industry, it is suitable for ultra-pure water, buffer solutions, and sterile fluid transfer; in the food and beverage industry, it is used for measuring beverages, dairy products, and other hygienic process fluids; in the water and wastewater industry, it is applied to drinking water treatment, wastewater monitoring, and chemical injection; in the petrochemical industry, it is used for measuring low-conductivity process water and additive dosing.
As a genuine Endress+Hauser product, the 5H2B Electromagnetic Flowmeter is manufactured with strict quality control, ensuring stable performance and long-term reliability. It is backed by Endress+Hauser’s global service network, providing users with professional technical support, maintenance services, and spare parts supply, reducing the total cost of ownership. The standard package includes the flowmeter body, user manual, installation guide, calibration certificate, and mounting brackets, ensuring convenient installation and use.
In summary, the 5H2B Electromagnetic Flowmeter combines high accuracy, stability, durability, and user-friendliness, making it an ideal choice for industrial flow measurement. Whether it is for small-flow measurement, corrosive medium measurement, or hygienic process measurement, it can meet the diverse needs of users, helping enterprises improve production efficiency, ensure product quality, and reduce operational costs.
