Flowline GT10 Series Thermo-FloTM Thermal Dispersion Air Flow Switch

Thermo-FloTM Thermal Dispersion Air Flow Switch
GT10 Series

The general purpose gas flow switch is a great choice for a broad range of relatively clean gases with non-coating characteristics. Media examples include nitrogen and scrubber exhaust fumes. The 1A relay provides a reliable switch interface with remote devices such as a PLC, SCADA or alarm. The short sensor is intended for use in pipe or ducting from 1/2” to 1-1/2”; the long sensor is applied in 2” and up. The switch set point may be adjusted from 1 to 90 fps. The product is broadly selected for low or no-flow applications.
