YPL online type plug (disc) operated magnetic flow switch Are suitable for sensing flow of liquids like oil, chemical or in Water lines. These switches can either be supplied in weather Proof housing.
Principle of Operation
Change in flow through valve body raises or lowers the plug Which causes attraction sleeve to move in the enclosing tube? The increase of flow causes flow plug to lift which causes attraction Sleeve to move up in the field of permanent magnet located outside The enclosing tube, which causes the switch to operate. When the Flow rate drops below the rate for which flow plug is calibrated, A reversal of this action takes place.
