Water Flow switches FSF series flow switches are used in measuring and controlling the flow of the liquid in the pipe, such as water, alcohol, etc.,as well as in the places where it needs chain effect or cutout protection. FSF series flow switches have SPDT switch, full-sealing structure as its shell, and stainless steel as its inside components, which can assure its use in any conditions. FSF-A series flow switches are used for caustic fluid liquid,the materials of FSF-A in contact with th medium is stainless steel. Approvals: DnV,Det norske Veritas(Norway),CQC(China),CE (Europe).
