Dwyer Instruments' Series TDFS Thermal Dispersion Flow Switch indicates whether the flow rate is above or below a user-set flow rate

W.E. Anderson Division of Dwyer Instruments introduces the Series TDFS Thermal Dispersion Flow Switch, which indicates whether the flow rate is above or below a user-set flow rate with NO and NC NPN outputs. Setpoint is field set when a user taps the included magnet on the setpoint target three times at the desired flow rate. Incorporated into the unit are two LED status indicators on opposite sides of the unit providing visual switch indication, green when the flow is above set point, red when the flow is below setpoint.

The TDFS uses an impulse thermal dispersion measurement technique to measure the flow rate where the probe is heated above the process temperature and then is allowed to cool down to the process temperature.
