product series features

Better 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 as it avoids overheating by actively heating above the process temperature and then cooling down to process temperature
Setpoint is easily field set by tapping the included magnet on the setpoint target three times at the desired flow rate
LED status indicators provide visual switch indication of flow rate in comparison to the setpoint
Low-pressure drop; only needs to be inserted 10% into the flow (e.g. 1/8Ë for 3/4Ë schedule 40 pipe)

Series Description

The Dwyer TDFS2 Series 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 field-adjustable, and the unit has both NO and NC NPN outputs.
