Page 3: General Description
General Description Notes The OMEGA ® FSW-50 Series Flow Switches feature a 15A SPDT switch and an internal screw adjustment which provides continuous switch point adjustment while in operation in-line. Multiple drag disks are supplied with each unit to provide incremental switch point adjustment. Their non- magnetic design makes them ideal for applications where rust is a problem. - Page 4 Notes Available Drag Disks The FSW-50 Series Switches come with three different drag disks. The drag disks are sized as follows: DRAG DISK SIZE .5" dia. .83" dia. 1.0" dia. The following table lists flow adjustment limits for various pipe sizes relative to Model No.

ASSEMBLY WARNING THE FSW-50 SERIES SWITCHES EMPLOY AN EXTERNAL SEAL SHAFT (A) A FLEXIBLE ELASTOMER DIAPHRAGM SEAL (B) AND AN INTERNAL FEED THRU SHAFT OR SWITCH ACTUATING ARM (D). ALL THREE ELEMENTS ARE ASSEMBLED AND LOCKED IN PLACE WITH LOCTITE ADHESIVE. TO PREVENT RUPTURE OF SEAL AND LEAKAGE INTO SWITCH AREA, IT IS CRITICALLY IMPORTANT THAT TORQUE NOT BE APPLIED TO SEAL SHAFT (A), FLOAT SHAFT (E) OR DRAG DISK ARM (E) DURING CHANGE 10402-6. -
