Flowline FT10 Series Thermo-Flo Thermal Dispersion Liquid Flow Switch
The general purpose liquid flow switch is an ideal choice for a wide range of relatively clean water and chemical solutions with non-coating and/or crystallizing characteristics. Media examples include deionized water and sulfuric acid. 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 from 1/2” to 1-1/2”; the long sensor is applied in 2” and up. The switch set point may be adjusted from .04 to 3 fps. The product is broadly selected for low or no-flow applications.
• Adjustable set point from .04-3 fps with LED for flow or no-flow status
• Solid state sensor is not damaged by over-ranging flow velocities
• 1A relay selectable NO or NC via power supply wiring polarity
