TheSeries TDFS2 Thermal Dispersion Flow Switchis 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. See Figure 1 on catalog page for output and LED actions on change of flow
