A flow switch is a device that monitors the flow of air, steam or liquid. It sends a “trip signal” to a different device in the system, such as a pump. The flow switch can indicate to the pump to shut off or to turn on, which will further protect it from damage and for cooling circuit protection.

• Flow switches are very reliable devices for determining flow rates.
• Flow switches also offer versatility, economy and accuracy.
• Some switches can be used to actuate audible or visual alarms, as well as relays or other controls.
• Can be used for a number of different applications, including industrial and biomedical to name a few.

• They have stable and lasting parts
• They require little power to work
• They give accurate and immediate results
• They are also cheap and readily available

• Pump protection
• Safety spray nozzle monitoring
• Cooling water or heat exchangers
• Oil well system testing
• Drain line flow
• Relief valve monitoring
