Thermo-Flo™ with Compact Junction Box
Application
Offered in liquid and gas sensor types, the general purpose flow switch package provides reliable no or low-flow detection of relatively clean non-coating media with a 1A relay output and compact junction box for wiring termination. Liquid examples includes water and acetic acid. Available in PP-Ryton® and PVDF, the short flow sensor is used in pipe or ducting from 1/2" to 1 1/2", and the long flow sensor is used in 2" and up. The flow switch set point may be adjusted from 0.04 to 3 fps in liquids, or 1 to 90 fps in gases as a low-flow alarm. The flow sensor is best applied in applications with relatively constant temperature.
Features
Rugged Polypropylene-Ryton® or PVDF sensor for corrosive liquids and gases
Adjustable set point with LED for flow or no-flow status indication
Polypropylene enclosure rated NEMA 4X with swivel base and terminal strip
60VA relay selectable NO or NC via power supply wiring polarity
Solid state sensor is not damaged by over-ranging flow velocities
