Thermal Dispersion Flow Switch delivers 0.07 fps repeatability.

Using impulse thermal dispersion measurement technique, Series TDFS indicates whether flow rate is above or below user-set value, from 0.5-10 fps, with NO and NC NPN outputs. Setpoint is field set by tapping included magnet on desired rate 3 times, and 2 LED status indicators on opposite sides of unit illuminate green and red when flow is above and below setpoint, respectively. Also, empty pipe...
