Detailed Product Description
FSF50P-3A FENSHEN Flow Switch is 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.
FSF50P-3A FENSHEN Flow Switch has SPDT switch, full-sealing structure as its shell, and stainless steel as its inside components, which can assure its use in any conditions.
FSF50P-3A FENSHEN Flow Switch is used for caustic fluid liquid, in contact with th medium is stainless steel.
Approvals: DnV,Det norske Veritas(Norway),CQC(China),CE (Europe).
