Versa-Switch Model FS51SC

Brand: DELTA M Corporation

  • Simple, field configurable Thermal Differential Mass Flow Switch for the detection of the mass flow rate of liquids and gases with time delay adjustable from 0 to 300 seconds.
  • Field selectable operating power 110Vac, 220Vac, or 24Vdc.
  • Wide operating temperature range -100°F to +850°F (-70°C to +458°C).
  • Wide operating flow range of .01 to 5 feet per second (fps) in oil, 2.5 fps in water and .1 to 500 fps in gases.
  • Removable, plug in electronics.
  • Free of all moving parts that can stick, coat or fail.
  • Fast response time of .5 to 10 seconds depending on the media.
  • Self heating sensor design improves repeatability. No separate heater to fail or slow response time.
