      Recently, Shaanxi Yid Intelligent Technology Co., Ltd. (referred to as "YIDU Intelligent") has made another major breakthrough in the field of mass flow controllers (referred to as "MFC"). Its independently developed series of mass flow controller products have successfully passed the European CE (Conformit é Europ é enne) certification.

This is also another international certification obtained by YIDU Intelligence after successfully obtaining the Certificate of Approval for Measuring Instruments (CPA certification: the highest authoritative certification in China). The dual certification of domestic CPA certification and international CE certification not only marks the excellence of the quality of YIDU Intelligent products, but also indicates that YIDU Intelligent's products can withstand various rigorous tests in domestic and foreign markets.

It is reported that the type approval certificate for measuring instruments (referred to as the type approval certificate) is an administrative license certificate issued by the national quality and technical supervision department (or market supervision and management department), which has high official authority and credibility. The CPA mark is a special mark for the type approval certificate of measuring instruments. This certificate is a recognition of the production capacity and product quality of the enterprise, and is an important guarantee for the stability of the quality and performance of measuring instruments.

CE certification, full name "Conformet é Europ é enne", meaning "European compliance", is an important measure taken by the European Union to strengthen regulation, protect consumer safety, the environment and health. CE certification marks that the product complies with the safety, health, and environmental protection requirements of the European Union and has received corresponding recognition. CE certification has a very high degree of recognition internationally, demonstrating higher quality and compliance.

Why develop laminar differential pressure MFC?

In today's rapidly advancing technology, China's manufacturing industry is rising at an unprecedented speed, especially in the field of precision instruments and control technology. However, currently, in the field of MFC, foreign manufacturers such as HORIBA, Brooks, Bronkhorst, MKS still dominate. Most of these companies enter the market with MFC based on the thermal principle, which adopts a semi empirical formula and is based on billions of experimental values as a reference. To achieve higher accuracy, only more experimental accumulation can improve precision. The reason why foreign hot brands have better accuracy than domestic brands is that the company was established earlier and accumulated more experimental data. After so many years of development, the thermal power generation has reached the limit of engineering technology and it is difficult to have room for improvement.

To break the international monopoly, domestic enterprises need to not only catch up with the technological level of existing manufacturers, but also gradually break the deadlock with outstanding innovation capabilities and solid product quality. The principle of laminar differential pressure will gradually become a future development trend. The principle of laminar differential pressure measures flow rate through differential pressure, and the differential pressure is proportional to the flow rate. The factors that affect accuracy are the resolution and accuracy of the sensor. Nowadays, the resolution and accuracy of sensors are getting better and better, and the accuracy of laminar differential pressure principle will be higher, with a lot of room for improvement.

The laminar differential pressure MFC regulates the gas flow state into regular laminar flow through laminar flow elements, and uses differential pressure sensors to measure the differential pressure at both ends of the laminar flow elements to calculate the gas flow rate. This method has high measurement accuracy and can meet the precise control requirements of gas flow in high-precision processes such as semiconductors, photovoltaics, and biomedicine. And laminar differential pressure MFC can measure gases from small to large flow rates, with a wide measurement range and suitable for various application scenarios. Meanwhile, compared to thermal MFC, it has no bypass capillary tube, a larger channel diameter, is less prone to blockage, and has strong anti pollution ability. The laminar differential pressure flow controller has a very broad market value and strategic significance due to its advantages of high precision, wide range, high repeatability, fast response, corrosion resistance, and high pressure resistance.

Therefore, in today's era of localization strategy, especially against the backdrop of the intensifying China US trade war, domestic enterprises urgently need to accelerate the pace of technological independence and controllability. Promoting the development of domestically produced laminar differential pressure MFCs not only contributes to technological autonomy and industrial upgrading, but also ensures information security, enhances economic and social benefits, and strengthens international competitiveness.

What is the strength of YIDU Intelligence?

Since its establishment, YIDU Intelligent has adhered to the entrepreneurial intention of "one small step for instruments, one big step for civilization", and is committed to the research and development of laminar differential pressure technology. The core R&D team is composed of several postdoctoral, doctoral, and master's students from Northwestern Polytechnical University, relying on the aviation and aerospace professional background of the R&D team, and based on fluid mechanics, materials science, embedded hardware and software development and other majors. With more than ten years of independent research and development, YIDU Intelligent has accumulated profound technical experience in laminar differential pressure principle, especially in the field of microflow measurement and control. Currently, it has obtained more than 20 innovative patent technologies and dozens of authoritative certifications at home and abroad. For many years, the company has adhered to scientific research and development principles, starting from a formula and gradually developing high-performance products. And it has obtained the highest technical certification (CPA) in China, and is also the first manufacturer of laminar mass flow meters and controllers in China.

The dual certification of domestic CPA certification and this international CE certification is a high recognition of the leading technology of YIDU Intelligent, and also the best proof of the company's continuous innovation ability and excellent product quality. Of particular note is that during the rigorous certification testing process, YIDU Intelligent's MFC products performed exceptionally well, not only passing all testing steps at once, but also demonstrating astonishing stability in electromagnetic compatibility (EMC) testing. It should be noted that electromagnetic compatibility testing simulates the performance of products in complex electromagnetic environments, and electric shock testing is the ultimate challenge to the equipment's ability to withstand extreme conditions. However, the MFC products of YIDU Intelligent can still maintain stable performance under such extreme conditions without any damage, which fully proves the rigor of its product design, the high quality of material selection, and the exquisite production technology. It also truly verifies the commitment of YIDU products to "solid and reliable" in customers' accounts.

YIDU EC series star products are gradually launched

The EC series products of YIDU Intelligent Quality Flow Controller, as a star product independently developed by the company, integrate high-precision sensing technology, intelligent algorithm control, and humanized interaction design, with high stability, reliability, repeatability, and cost-effectiveness. This product can achieve precise measurement and control of fluid mass flow rate, and is widely used in multiple industries such as environmental protection, semiconductor, chemical, hydrogen energy, photovoltaics, vacuum coating, pharmaceuticals, and food, providing strong guarantees for precise control and efficiency improvement of production processes. As a new product of YIDU, it obtained CE certification immediately after its launch. In the future, YIDU will continue to release other models of EC series products, continue to give back to customers with excellent technical strength and solid product quality, and use this as a new starting point to continue moving forward in the MFC field, providing more accurate and reliable intelligent control solutions for global customers, and contributing to the rise of China's manufacturing industry.

       In the future, we have reason to believe that YIDU Intelligence will continue to uphold its original intention, forge ahead, create more glory in the MFC field, and win more international praise for Chinese manufacturing.
