Offered in liquid and gas configurations for low-flow detection, the general purpose flow switch is a great choice for a diverse range of relatively clean, non-coating media. Liquid examples include deionized water and sulfuric acid. Gas 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 11/2”; the long sensor is applied in 2” and up. The liquid switch set point may be adjusted from .04 to 3 fps, and the gas switch from 1 to 90 fps.
Features
