The semiconductor manufacturing process demands an extremely high level of purity in the fluids used, especially super pure water. For instance, in a leading semiconductor fabrication plant like TSMC, during the wafer cleaning process, any impurity in the water can cause defects on the wafer surface. Traditional flow meters like electromagnetic flow meters, which rely on the conductivity of the fluid, are rendered ineffective when it comes to measuring the flow of super pure water as it has negligible conductivity. This is where the RBFM-K/RBFM-MK models shine. Their ultrasonic technology allows for accurate flow measurement even in non-conductive fluids like super pure water, ensuring that the semiconductor production process is not compromised due to inaccurate flow data. The industry commonly employs stainless steel pipes ranging from DN15 to DN65. The compact and clamp-on design of these ultrasonic flow meters is perfectly suited for such pipe sizes. Installation is a breeze as they can be simply clamped onto the outside of the pipes without the need for any invasive procedures or cutting of the pipes. In a Samsung semiconductor facility, the installation of RBFM-K/RBFM-MK meters on their chemical delivery lines, which are mainly DN25 stainless steel pipes, was completed within a few hours without disrupting the production process. This not only saved time and effort but also minimized the risk of contamination or damage to the piping system, which is of utmost importance in the semiconductor environment. Another significant advantage is the ability to easily obtain accurate flow readings over different time periods. Whether it's daily, monthly, or annual flow data, these meters provide reliable and precise measurements. In an Intel semiconductor plant, the RBFM-K/RBFM-MK meters have been used to monitor the flow of cooling water over the past year. The accurate flow readings have enabled the plant to optimize the cooling system, ensuring the stable operation of the semiconductor manufacturing equipment and reducing the risk of overheating-related failures. When compared to other available options in the market, such as the products from Keyence (https://www.keyence.com/products/process/flow/fd-h/), the RBFM-K/RBFM-MK models offer a unique combination of features that are specifically tailored to the needs of the semiconductor industry. Their ability to handle non-conductive fluids, ease of installation on the standard stainless steel pipes, and accurate long-term flow measurement capabilities set them apart.
In conclusion, the RBFM-K/RBFM-MK compact clamp-on ultrasonic flow meters have become widely adopted in the semiconductor industry due to their unmatched performance in measuring super pure water flow, convenient installation process, and reliable flow reading capabilities. They are an essential tool for ensuring the smooth and efficient operation of semiconductor manufacturing processes, where even the slightest deviation in fluid flow can have a significant impact on the final product quality.
