Methanol transfer pump and control valve flow meter

I understand that the original poster is looking for recommendations on equipment selection for transporting methanol, especially where high cleanliness standards are required. Regarding the selection of flow meters for methanol transfer pumps and control valves, it is recommended to give priority to equipment made of 316L stainless steel, as this material offers good corrosion resistance and is not prone to being contaminated by the medium. Additionally, it is worth checking whether the equipment has FDA or GMP certification, as such certifications generally require stricter standards regarding cleanliness. However, the specific selection still needs to be determined based on parameters such as flow rate and pressure. It is recommended that the original poster provide more details so that everyone can give more accurate suggestions. It’s best to consult the manufacturer’s engineers regarding professional equipment~
