FS50 paddle flow switch comprises a paddle system with a permanent magnetattached. It follows the simple and reliable design concept and greatly improves thereliability of the flow switch from the structure, which is not comparable to thetraditional target type flow switch. Mechanical flow switch with built-in micro trigger switch, very small pressure loss, good repeatability, and high dirt resistance. The mechanical part is safely isolated from the electrical part.Pipeline type baffle type flow switch does not contain bellows that are prone to failure, the electrical parts do not directly do not directly contact with metal parts with large temperature difference, there is no problem of condensation generated by the electrical parts leading to rust and corrosion. The product uses the imported micro switch as the electrical action parts, through the current is large, completely avoid the problem of improper use of the min switch easily damaged, suitable for central air conditioning and industrial fluid control.
