The FS vertical fitting range of Flow Switches is supplied in FS-050V-1 LPM switch level or FS-075V-3 LPM sensing level. A spring loaded magnet detects the liquid flow and operates a 240Vdc.0.5A.50W reed switch contact. The housing has a standard BSP threaded in/outlet. Although these two types are designed to be fitted in a vertical position the FS range can be supplied in a range of configurations including horizontal and vertical fitting and flow sensing levels of 1 to 16 LPM.
