COMPANY PROFILE
Weihai Duoterui Automation Equipment Co., Ltd., founded on July 15, 2016, is a tech-oriented enterprise integrating R&D, manufacturing and international trade. Specializing in flow measurement, it dedicates to the R&D, production, sales and technical services of various flow meters, supplying high-quality, reliable and intelligent flow measurement solutions for global industrial clients. Since establishment, the company has adhered to the tenet of Technology Priority, Quality Foundation, Customer Centricity. Supported by professional technology, standardized production and considerate after-sales service, it has earned solid reputation in the automation instrumentation industry and become a reliable partner for domestic and overseas enterprises.
As an energetic enterprise, Duoterui highly values hardware construction and product testing capability as the core guarantee of quality. It has built a full professional testing center equipped with advanced inspection and calibration devices covering the whole production process from raw material incoming inspection to finished product delivery. The supporting facilities include standard flow calibration devices, sonic nozzle calibration equipment for high-precision gas meter calibration, circuit aging test equipment, high-low temperature test chambers, pressure testing devices and vibration test machines. The complete quality control system strictly regulates every production procedure to ensure all flow meters feature superior performance, high accuracy and stable reliability.
With profound technical accumulation in vortex flow meters, the company targets common industrial pain points of conventional models such as narrow measuring range, weak anti-vibration performance and unstable signals. Its R&D team, consisting of senior fluid measurement engineers and experts, optimized sensor structure, upgraded signal processing algorithms and enhanced anti-interference design, and developed a new-generation vortex flow meter with wide turndown ratio and strong vibration resistance. Inheriting the merits of simple structure, stable operation and low maintenance, the product is widely applied in petrochemical, chemical, water supply & drainage, pharmaceutical, food and metallurgy industries, perfectly meeting refined control and precise measurement demands of industrial automation.
Keeping pace with global digitalization and intelligentization trends, Duoterui integrates flow measurement with IoT technology and independently developed a cloud monitoring & management platform for flow meters. Supported by IoT communication, cloud storage and remote transmission technologies, the platform eliminates traditional on-site manual meter reading. Clients can access the system via mobile phones and computers to realize remote real-time monitoring, historical data query, equipment early warning and long-distance management. It effectively cuts labor and management costs, provides accurate data for production scheduling, energy statistics and process optimization, and empowers users to achieve digital and intelligent upgrading of flow measurement.
Through years of steady development and capacity expansion, the company has formed a standardized, large-scale and serialized production system with sufficient annual output to satisfy diversified domestic and overseas orders. Its annual production capacity reaches 50, 000 vortex flowmeters, 10, 000 thermal gas mass flowmeters, 20, 000 electromagnetic flowmeters, and 10, 000 other flow meters and supporting instruments including rotameters, turbine flowmeters and flow controllers. The full product portfolio enables the company to provide one-stop flow measurement solutions for global customers.
