Flow switches mount directly in flow stream for line pressures from 1500 to 5000 psig. Fixed-orifice models are rated for low flows from 0-2 to 0-40 gal/hr and 1.5-5 scfm. Variable-orifice models are rated for flows from 0-1 to 0-30 gpm and 1.5-10 to 1-100 scfm. Both use adjustable, hermetically sealed reed switches to control processes or initiate high/low alarms or indicators. They come with or without enclosures.
