The FS range of flow switches uses the flow of liquid within a pipe to move the switch’s paddle and operate a reed switch contact. The paddle is manufactured in Teflon and stainless steel and can withstand a pressure of 2448kPa. The paddle is marked in 0.5in increments which enables the length to be cut to suit a wide range of volumes from 23 to 100 litre/min. The switch is fitted to the diameter of the pipe using the 1in PT thread. With a high flow, shock and vibration rating, and an explosion-proof option (FS70 model), the switch is suitable in a wide range of environments and liquids.
