XX Group is a major Chinese chemical enterprise specializing in R&D and production of pigments and key intermediates, making it a leading player in the pigment sector. Through long-term cooperation, we have consistently supplied electromagnetic flowmeters to both its parent company and various subsidiaries. These products are widely used in critical processes, including pigment synthesis, transport of acidic media, slurry circulation, water treatment, and environmental protection systems. Operating under complex conditions involving corrosive media, fluids containing solid particles, and large-diameter pipelines, our electromagnetic flowmeters meet the stringent requirements of chemical production in terms of stability, corrosion resistance, and measurement accuracy. Through continuous support across multiple projects and facilities, we have not only established a strong cooperative relationship but also provided reliable assurance for precise measurement and safe operation in their chemical pigment production processes.
