WeiHai DuoTeRui Automation Equipment Co., Ltd. was established on July 15, 2016. It mainly engages in the R&D, production and sales of flow meters, and is a technology-based enterprise integrating science, industry and trade.
The company's main products include the following flow meter types: vortex flow meters, thermal gas mass flow meters, swirl flow meters, gas turbine flow meters, roots flow meters, liquid turbine flow meters, metal tube rotameters, electromagnetic flow meters, and throttling devices. Its annual sales volume exceeded 20,000 units in 2024. These products are widely used in industrial technology and management sectors such as chemical engineering, environmental protection, metallurgy, pharmaceuticals, papermaking, and water drainage, and have won consistent praise from customers.
The company has an independent R&D laboratory, enabling it to independently complete the customization, design and development of special products. Customization for a single unit is available, which maximizes the satisfaction of customers' personalized needs. In 2023, the company's independently developed isolated and anti-vibration vortex flow meter won the "Top 10 New Products of the Year" award from the Chinese Society of Instrumentation and the Shandong Provincial Innovation Award in 2024. In on-site applications involving high temperature, high pressure and high interference—especially in the domestic thermal power industry—it has gained high recognition from users. This product can replace imported foreign brands and even outperforms them in performance.

In the process of technical accumulation, the company has achieved effective connection among three generations of engineers (senior, middle-aged, and young). It not only has the rich experience of senior engineers for guidance but also relies on the successive on-site services provided by middle-aged and young engineers. After years of accumulation, the company has amassed profound experience in the industry.
We do not cling to outdated conventions or rest on our laurels; instead, we always maintain a modest and prudent attitude, pursue innovation with determination, and strive for continuous progress. We value and respect talents, activate their subjective initiative, and have created a work environment that is both dynamic and disciplined, as well as earnest and rigorous. After more than a decade of development, the company has accumulated extensive service and application experience in the application of various products across diverse industries, providing solid support for the safe and accurate measurement needs of our customers.
After five years of accumulation and consolidation in the industry, the company was officially registered in 2016, with the R&D department established; its single product – the vortex flow meter – took the lead in sales.
The company has moved to a new factory, expanded its scale, extended its production lines, realized the diversified production of products, and initiated the project for R&D of gas metering products.
The gas metering products have entered mass production, with their market share further expanded. Meanwhile, the production lines are developing toward standardization and integration.
The company has achieved leapfrog development and forged ahead with remarkable momentum to expand its scale, while taking standardized production to a higher level.
The products are iteratively updated, the production lines have been expanded to cover a complete range of product categories, and the products hold full qualification certifications.
In the post-pandemic era, the company forged ahead against the trend: it built a new-type laboratory in Weihai to strengthen R&D efforts; established a production base in Jiangsu to ensure product quality; and fully launched the third-generation Internet of Things (IoT) system, which significantly boosted product sales.
The company has further expanded its scale, with 4 additional sets of experimental equipment, making it a leading manufacturer in terms of calibration capabilities in Shandong Province. It has invested heavily in the R&D of vortex flow sensors; its isolated and anti-vibration vortex flow meter was named one of the "Top 10 New Products of 2024" by the Chinese Society of Instrumentation and also won the Shandong Provincial Innovation Award. Product sales have increased by 40%, and its flow meter production line ranks among the top in Shandong Province.
In 2025, Doterra Automation reached new heights in the field of product technological innovation. Its independently developed "Structural Anti-Vibration Vortex Flow Meter" made a grand debut at the influential Zibo Chemical Industry Exhibition this year, immediately becoming the focus of attention at the exhibition and triggering enthusiastic responses and high praise from users and industry peers.
