FLOW SWITCHES FS-200 Series General Purpose, FS-200 Series Straight-Through Flow Path Flow Rate Settings: Fixed: 0.5 GPM to 100.0 GPM Adjustable: 1.0 GPM to 15.0 GPM U.L. Recognized File No. E31926 CSA Listed Port Size: 1 NPT to 2 NPT File No. LR30200 and LR22666 Primary Construction Material: Bronze or Stainless Steel FM Approved File No. 0A8A3.AE Setting Type: Fixed or Adjustable and 1H3A2.AX The FS-200 Series offers accurate flow detection, with 1% repeatability, over a broad range of flow settings and port sizes. Its durable construction delivers long-life reliability in either water or oil. Generous flow paths keep pressure drop low. These switches are ideal for detection of improper flow rates in high volume lubrication, cooling or process systems. FS-200 Adjustable FS-200 Adjustable Series switches offer the same accuracy and are as rugged as those G-4 ill with fixed settings, but provide one additional feature: external adjustability. With these versatile switches your choice of ofl w settings is diverse within a given range. An U.L. Recognized ordinary, flat-blade screwdriver is all thats required for the actuation adjustment.
