Flowline flow switch & control for liquid & air/gas Flowline's liquid and gas flow switches are simple devices that are used to detect or monitor flow and send a signal or alarm to another device. They are useful tools in situations where it is important to know whether or not flow exists and to act upon that knowledge (for example they can be used to actuate a signal when flow stops, start a motor with flow, shut off an alarm when flow is adequate or stop a motor with no flow). Flow switches are used for a wide range of applications; some typical uses include:
The Thermo Flo is offered in PP or PVDF materials with a 1A relay for reliable switch interface with remote devices such as PLC, SCADA or alarm. It is available in short or long lengths: 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 0.04 to 3 fps, and the gas switch from 1 to 90 fps.
