Flowline Thermo-Flo™ AT18 with Compact Junction Box, General Purpose, Liquid, PP, 2.8" (71mm) Long Sensor, (1) SPST Relay, ¾” NPT, PP Enclosure, NEMA 4X, 14-36 VDC, Adjustable Flow Switch Set Point

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 include 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.
