1. Superior Severe Environment Resistance：Made of high-corrosion-resistant alloy, it can withstand high temperature (up to 815℃), high pressure (up to 414 bar) and high-viscosity medium impact. It operates stably in severe service conditions such as chemical high-temperature reactors and oil & gas deep well extraction, avoiding measurement deviations caused by environmental erosion.

2. Accurate Flow Measurement Technology：The innovative Annubar sensing structure can accurately capture the average fluid velocity, with a measurement accuracy of ±0.5% and a repeatability error of ＜±0.1%. Even under severe service conditions with large fluid fluctuations, it can provide reliable flow data support for production.

3. Low-Maintenance & Long-Lifespan Performance：The element surface is treated with special anti-scaling technology to reduce blockage caused by medium adhesion. There are no vulnerable moving parts inside, and its service life is more than 50% longer than traditional primary elements, lowering equipment maintenance costs and downtime risks in severe service conditions.

1. Professional Adaptability to Severe Service Conditions：Developed specifically for severe service conditions in chemical, oil & gas, power and other industries, it has undergone tens of thousands of on-site condition tests. It can cope with complex environments such as corrosion, high temperature and high pressure without additional protective devices, reducing equipment adaptation costs.

2. Reliable Brand Endorsement：As a global leader in process measurement, Rosemount 585Annubar Primary Element has passed ISO 9001 quality certification and ATEX, IECEx explosion-proof certifications. It is widely used in severe service scenarios in more than 200 countries and regions around the world, with dual guarantees of customer reputation and product performance.

3. Full-Cycle Service Support：From selection consultation to installation guidance and later maintenance, a professional technical team provides full-process support. Customized solutions can be provided for special needs under severe service conditions to ensure long-term stable operation of equipment and reduce production interruption losses.
