Dwyer Instruments: Series TDFS, Thermal Dispersion Flow Switch
Non-Mechanical, Low Pressure Drop
The SERIES TDFS Thermal Flow Switch uses impulse thermal dispersion measurement technique to indicate whether the flow rate is above or below a user set flow rate. It provides NO and NC NPN outputs and two LED, one green and one red for high and low set point indication.
SERIES TDFS Applications
- Boiler flow proving
- Hot water heaters
- Chillers
- Liquid transfer systems
