Utilize Swagelok® FV4 series flow sensors to precisely monitor variations in gas system flow. These sensors feature a snap-action float mechanism with a calibrated orifice that moves vertically within the float guide, enabling precise actuation for accurate gas flow detection as the flow rate changes. The embedded magnet in the float above the orifice alternates electrical continuity between the leads on a nearby reed switch, thereby detecting flow fluctuations.
Constructed entirely of welded 316L stainless steel, these sensors offer robust durability and secure fluid containment. Additionally, the replaceable switch assembly located outside the flow path facilitates straightforward maintenance. The FV4 series flow sensors are designed to withstand working pressures up to 5000 psig (344 bar).
