FS15A

FS Series Flow Switches Flow detection switches 15mm and 22mm tube versions Low flow version available in 15mm tube Maximum Operating Pressure 10 bar WRAS approved for use in cold and hot water up to 85ºC Temperature rated to 85ºC Technical Specification Material Colour Temp. Range °C °F Must operate flow rate* Must release flow rate # These flow switches are designed for use in liquid flow systems at pressures up to 10 bar and temperatures up to 85ºC. The design is based around a moving magnet and a fixed reed switch with a low flow restriction. The switches are designed to be used in liquids only and should not be used in systems with significant amounts of solid particles.

NB Operate and release flow rates only apply when the switch is mounted with the flow direction vertical. The sensitivity of the switch is reduced when mounted with the flow direction horizontal. 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.
