FS20 is an online installation, mechanical water flow switch used for liquid or gas media. The mechanical and electronic parts are completely isolated, suitable for low flow economy models. Three times the piston stroke of the original FCS20 makes the setting accuracy more precise. Equipped with a switch setting scale, users do not need to set it on site.
