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 PP-Ryton® or PVDF sensor for corrosive liquids and gases
- Adjustable set point with LED for flow or no-flow status indication
- PP 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
