Standard Parts Must operate l/min Must release l/min Approvals The design is based around a moving FS15A 2.0 0.3 WRAS FS15LF 0.90 0.25 WRAS magnet and a fixed reed switch with a low FS22A 3.75 1.40 WRAS flow restriction. * The switch will have operated (contacts close) when the flow rate rises above this value. The switches are designed to be used in # The switch will have released (contacts open) when the flow rate falls below this value. liquids only and should not be used in NB Operate and release flow rates only apply when the switch is mounted with the flow direction vertical. The systems with significant amounts of solid sensitivity of the switch is reduced when mounted with the flow direction horizontal. particles. Installation Flow switches can be mounted with the flow direction horizontal or vertical (upward flow). The cap with cable connection must always be upwards, as the piston is returned to its released position by gravity. Custom versions can be made for particular applications.
