Gems Sensors Series Flow Switch

 Straight Flow Path with Low Pressure Drop

Quick Specs... 

  • Flow Rate Settings: Liquids 0.5 GPM to 5 GPM 
  • Port Size: 1/2" NPT 
  • Primary Construction Material: Polypropylene 
  • Setting Type: Fixed  

 

Overview / Design Principle: 

These slim, inline switches reduce pressure drop to a minimum. They incorporate a unique, dual-diameter, internal bore and piston configuration to minimize flow constriction. Liquids are able to smoothly pass around the piston and flow through the switch with little pressure loss to the down stream line. 

Applications: 

  • Electronic Equipment: Laser Heads, Welders, Power Supplies, High Speed Spindles, X-Ray Tubes, Semiconductor Equipment 
  • Bearings or Gears: Presses, Rotating Equipment, Conveyors, Machine Tools, Robotics 
  • Processing & Dispensing Equipment: Water Purifications and Filtering, X-Ray Film Processing, Beverage Dispensing, Chemical Additives, Gas Sampling, Distilling
