What does a water flow switch do?
A waterflow switch is the interface between the building’s fire suppression system and the building’s fire alarm system. It detects water flowing in the sprinkler system and causes the fire alarm system to sound the evacuation.
How does a flow control switch work?
A flow switch operates by conveying a trip motion (relay, reed switch, paddle) to another machine within the system, usually a pump. The trip signal will indicate to the pump to turn on or turn off. It is necessary to provide damage protection and circuit cooling or adjust flow rates that are too high or too low.
What are flow switches?
A flow switch, sometimes referred to as a flow sensor or flow indicator, is a device used to monitor the flow rate and pressure of liquids, air or other gaseous media through a duct, system or loop.

How are flow switches used in HVAC systems?
The flow switches are designed for monitoring flow rates in pipes employed in HVAC applications. For monitoring flow in water, oil, cooling circuits, and lubrication systems. Media temp.
What kind of sensors are used for water flow?
The System Sensor T-Tap Water Flow Detectors are WFDTH Retard T-Tap Water Flow Detectors designed for primary signaling in residential systems and fits within 2×4 stud wall construction. WFDTN t-tap water flow detectors consist of a rugged, NEMA 4 rated enclosure that is more damage resistant than previous metal designs.
When do you need a WFS flow switch?
All series WFS flow switches are designed for use only as operating controls. Where an operating control failure would result in personal injury and/or loss of property, it is the responsibility of user to add safety devices that protect against, or supervisory systems that warn of control failure.
