Flow Switches

Flow Detection, Switching & Control

Flow switches detect a change in state from flow or no-flow within pipe or ducting. Correspondingly, the sensor inverts a contact to signal an alarm or control a pump or valve.

Flowline general purpose liquid and gas flow switches are offered in sensor and package configurations. Sensors are available in PP-Ryton® or PVDF bodies with a 1A SPST relay and adjustable flow switch set point.

The sensors are also available in packages with compact relay controllers for pump control or junction boxes for wiring termination. Select the appropriate flow switch type based upon your application media, supply, control and installation requirements.

Application

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.
