SF1800 – Stainless Steel Paddle Flow Switch

The SF1800 Flow switch detects liquid movement in pipes, when the liquid is static or non-existent, the spring is fully extended, pulling the magnet downward and opening the switch.

As flow occurs and the paddle is thrusted forward 20~30 degrees or more, the paddle will push the magnet upward and actuate the switch (closing the circuit). The length of paddle can be adjusted to the pipe’s diameter.
