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. The FSW-50 comes standard in a plastic/316SS construction. The FSW-50 Series is also available in a special PPS* Ha

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 #1 .5" dia. #2 .83" dia. #3 1.0" dia. The following table lists flow adjustment limits for various pipe sizes relative to Model No. and drag disk size. The moment arm (see Step 3 of FLOW RANGE) is held constant at the maximum value. Decreasing the moment arm, increases the adjustment range. Low Flow Nominal Pipe Nominal High Flow % Increase Model Low Flo

6. If the system flow rate is changed, the FSW-50 can be adjusted to Figure 2: Wiring Schematic for power applied to load when the flow is greater than set point (power to load interrupted when flow decreases to below set monitor the new flow rate by turning the adjusting screw in a counterclockwise direction to the minimum flow position and then point). proceeding as in Step 4 above. 7. In the event that the system flow is at the desired rate and the adjustment mechanism runs out of travel, i.e
