This manual introduces the features and characteristics of the Thermo-Flo™ Thermal Dispersion Flow Switch FT10 and GT10 series products, including providing reliable low or no-flow detection, clean, non-coating media, 1A relay output, short flow sensor can be used in ½” to 1-1/2” pipe or duct, long flow sensor can be used in 2” and up pipe or duct, flow switch set point can be adjusted to 0.04 to 3 fps of liquid or 1 to 90 fps of gas as a low flow alarm.
This manual provides instructions for the Flowline Thermo-Flo™ Thermal Dispersion Flow Switch FT10 and GT10 Series. The FT10 series is designed for liquid flow detection, while the GT10 series is intended for gas applications. Both sensors utilize thermal dispersion technology to measure flow velocity by detecting temperature changes in the fluid.
