Dwyer FS-2 vane-actuated flow switch
I've used this flow switch on numerous projects and have found it to be a reliable and economical choice. Installation is quick and straightforward, and the adjustable vane design makes it adaptable to a wide range of pipe sizes and configurations.
My only minor critique is that the vane is only available in stainless steel. In applications involving high chlorine levels, a more chemically compatible material would be preferable. Offering additional vane material options would make this an even more versatile product.
