SKYWEAL水流开关 Flow detection switches FS Series Flow Switches FS-133 G3/4 tube versions Low flow version available in G 3/4 tube Maximum Operating Pressure 10 bar WRAS approved for use in cold and hot water up to 105ºC Temperature rated to105ºC These flow switches are designed for use in liquid flow systems at pressures up to 10 bar and temperatures up to 105ºC. 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. Technical Specification Material PA+GF Colour Black Temp.

Please contact Cynergy3 with your requirements. * The switch will have operated (contacts close) when the flow rate rises above this value. # The switch will have released (contacts open) when the flow rate falls below this value. 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.
