FLUIDYNE MAGNETIC & BELLOWS SEALED flow switches are versatile instruments designed to handle any fluid. Standard materials of construction and glandless design offered render the switches compatible with most of the corrosive and toxic fluids. The easy-to-fix design reduces installation costs and time. Simple mechanical parts ensures high reliability and zero - failures. The microswitch of the instrument is operated by the deflection of paddle or plunge assembly due to velocity of flowing-fluid against the restraining force of the range spring through a magnetic scaled lever at a predetermined flow rate.
FLUIDYNE switch also senses flow - no flow, responding only to the velocity of fluid movement in a duct.They provide a positive signal to detect change or loss of flow velocity caused by closed damper, a loose fan wheel, a slipped or broken fan belt, a dirty or clogged filter or even an overload to fan motor. Large paddle are used for reliable velocity switching. There are following types of Flow Switches:-
Plunger Type Flow Switch
Paddle Type Flow Switch
