Series 810 Hermetically Sealed Flow Switch Application The Model 810 Hermetically Sealed Level Control is a vertical mounted switch used to monitor "flow vs. no-flow". Its purpose is to operate valves, alarms, control pumps or any other electrical function.
Features • Corrosion Proof: All 316 Stainless Steel wetted parts. • Adjustments: Nothing to adjust or get out of calibration. • Hermetically Sealed Switch • Replacement Switch Capsule: Can easily be changed in field. • No Seals or O-Rings to replace.
Operation The weight of the vane causes the magnetic arm to drop away from the switch with a flow .75 ft./sec. or less. Fluid flowing 1.0 ft./sec. causes the vane to move, thus moving the magnetic arm to actuate the switch.
