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:
Low flow pump and process protection
Ensuring sufficient flow of coolants and lubricants
Leak detection eg in valves, seals, pipeline fittings
Signalling No Flow or Low Flow in cooling circuits
Chemical injection flow monitoring
Warning of air leakage in compressed air systems
High Flow and Low Flow alarm and general flow monitoring
Reverse flow detection and monitoring
The Thermo-Flo™ is a general purpose flow switch from Flowline offered in liquid or gas configurations
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.
Adjustable set point with LED for flow or no-flow status indication
Solid state sensor is not damaged by over-ranging flow velocities
Compatible with Flowline alarm, controller and fitting accessories
