On June 4, at the SNEC Photovoltaic Conference in 2026, Digital New Energy DataBM
. Yidu Intelligence, with its self-developed laminar flow differential pressure principle gas mass flowmeter and flow controller (MFC) , made a major appearance.
According to Huang Pan, the company's sales director, unlike the traditional thermal MFC on the market, the product innovation of Yidu Intelligence adopts pure mechanical structure design, and there are no moving parts inside the equipment, which achieves a breakthrough in upgrading product performance from the hardware root.
In addition, the traditional thermal MFC has many industry pain points for a long time, which is also a major problem faced by photovoltaic precision production. This kind of equipment needs to be preheated and waited in advance after starting up, and is easily affected by the fluctuation of ambient temperature and air pressure, so the measurement accuracy and stability are insufficient. In the interview,
Huang Pan said frankly that the technology of easy and intelligent laminar flow pressure difference avoids the above shortcomings and realizes the efficient operation mode of starting up and using without preheating . The error caused by the fluctuation of temperature and air pressure is negligible ; At the same time, the product has excellent long-term operation stability, and the flow control accuracy can reach ± 0.

Among them, the new T series is mainly integrated equipment. The compact body of the product can be flexibly embedded in the interior of instruments and equipment, process gas circuit panels and automatic gas supply cabinets to help customers save installation space, optimize the structure of the whole machine and reduce assembly costs.
P series aims at the metrology calibration market, mainly supplying quality inspection workshops and equipment operation and maintenance laboratories of metrology institutes and flowmeter manufacturers. As standard calibration equipment, it can calibrate various brands of flow controllers on the market, help customers streamline calibration instruments, and improve the efficiency of delivery and inspection.
Precise flow control!
In the photovoltaic industry, the core processes of battery manufacturing, from diffusion doping, PECVD coating, to dry etching, ALD coating deposition, rely on the precise supply of special process gases, and the stable operation of the whole production line can not be separated from the precise control of MFC.
Speaking of specific application scenarios, Huang Pan took the core PECVD coating process as an example to DataBM, a digital new energy source. It will lead to ". On the contrary, the gas flow can be stably controlled by relying on the high precision MFC of Yidu Intelligence. It can not only guarantee the coating accuracy and improve the battery conversion efficiency, but also reduce the frequency of production line shutdown and commissioning, reduce the material loss of special process gases, and help enterprises reduce costs and increase efficiency in an all-round way.
Finally, Huang Pan summed up in one sentence, "If the gas flow can not be controlled, the whole batch of photovoltaic products may be scrapped." . Under the general trend of
domestic substitution, where will MFC go next? In Huang Pan's view, the industry " is to import according to the standard and improve the stability and reliability of products. In the past, the high-end MFC market has been monopolized by imported brands for a long time, and the core gap lies in product stability and durability. Nowadays, domestic manufacturers can effectively reduce the probability of equipment failure, ensure the uninterrupted and smooth operation of production lines for a long time, and reduce the cost of maintenance and operation and maintenance by optimizing the product structure and improving the quality of workmanship.
The second is technology iteration, upgrading from traditional thermal MFC to laminar differential pressure MFC. Compared with the traditional thermal type, the technical scene adaptability and durability of the laminar flow differential pressure type MFC are more prominent: it is not interfered by the change of gas composition, the temperature and pressure fluctuation is less affected, and the ventilation does not need to be re-calibrated; there are no vulnerable heating components such as thermal sensitive wires inside, which can resist dust and corrosive gases, and the service life is longer; In addition, the zero drift is very low, and there is no need to stop calibration frequently for long-term production.
Huang Pan said that for precision manufacturing enterprises such as photovoltaics and semiconductors, the replacement of laminar flow differential pressure MFC can not only save the labor and time cost of regular equipment inspection and shutdown commissioning, but also avoid the problem of batch product scrap caused by flow deviation from the source. The effect of cost reduction and efficiency enhancement is intuitive and visible. The hard core of postscript
technology is the core of product iteration. As early as May 24, Yidu Intelligence, relying on its technical strength, as the only enterprise drafting unit, deeply participated in the revision of the two national standards of "Laminar Flow Meter Verification Regulations" and "Laminar Flow Meter Type Evaluation Outline" .
In the future, Yidu Intelligence will continue to cultivate the precision gas flow control track, adhere to technological innovation and product iteration , continue to polish high-precision, high-stability, long-life flow control products , and enable the fine development of the photovoltaic industry.
