Sensata / Cynergy3 FSP10 Series In-line Flow Switch for Liquid, 3 L/min Min, 80 L/min Max

This in-line flow switch from Sensata Cynergy3 directly controls an electric pump. It's used in gravity-fed systems to increase the pressure or flow of water. Its brass tube is strong and corrosion-resistant for a durable, long-lasting connection to a pipe. As it automatically starts a pump when the flow rate exceeds 3L/min (litres per minute), there's no need for manual intervention, making it simple to use. When water demand recedes or a tank empties, it turns the pump off. You'll find switches like this one used in irrigation and plumbing systems.

• Polyamide (PA) housing that's resistant to wear for an extended service life
• IP54 (ingress protection) rating for protection against dust and water splashes from any direction
• Supplied with electrical terminations for convenient installation

You should install this in-line flow switch in a pipe directly above the pump. As its operation relies upon water flowing against gravity, you should mount it vertically with the flow direction upward.

You can check the function of the switch by using the test button that's located underneath the device.
