Non-Mechanical, Low Pressure Drop

The SERIES TDFS Thermal Flow Switch uses impulse thermal dispersion measurement technique to indicate whether the flow rate is above or below a user set flow rate. It provides NO and NC NPN outputs and two LED, one green and one red for high and low set point indication.

Product Applications

  • Boiler flow proving
  • Hot water heaters
  • Chillers
  • Liquid transfer systems
  • Better long term reliability and life expectancy than mechanical flow switches with no paddles or vanes to wear or break, no jams in the paddle movement, and no seals on movement assembly to wear or leak
  • Not affected by empty pipe detection and avoids overheating by actively heating above the process temperature and then cooling down to process temperature
  • Set point is easily field set by taping the included magnet on the set point target three times at the desired flow rate
  • LED status indicators provide visual switch indication of set point
  • Low pressure drop, only needs to be 10% into the flow (e.g. 1/8" for 3/4" schedule 40 pipe)
