The FS-11 Flow Switch monitors water flow through your system by detecting the movement of water through the heater. As water passes through the switch, an internal paddle activates, opening or closing the electrical circuit depending on whether flow is present. This provides reliable flow detection to help protect equipment from running without adequate water circulation.

• Reliable operation – Simple mechanical design provides stable performance and a long service life.
• Compact and lightweight – Easy to install where space is limited.
• High pressure resistance – Suitable for systems operating at pressures of up to 1 MPa (10 bar).
• Weather-resistant construction – Designed for both indoor and outdoor applications with a high level of environmental protection.
• Adjustable flow setting – Flow activation point can be adjusted to suit the requirements of your system.
• Wide range of applications – Suitable for hot tubs, swimming pools, water heaters, central air conditioning systems, water meters, coffee machines and other water circulation equipment.
