Measure and control flow of liquids
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 by avoiding overheating with heating above the process temperature and then cooling down to process temperature
Lower system run cost due to low pressure drop with 10% insertion into the flow (e.g. 1/8" for 3/4" schedule 40 pipe)

The Series TDFS2 Thermal Dispersion Flow Switch is a thermal flow switch that indicates whether the flow rate is above or below a user set flow rate. The unit incorporates two LED status indicators providing visual switch indication. The set flow rate (setpoint) is easily field adjustable with included magnet and the unit has both NO and NC NPN outputs.
