Adjustable lowflow models have a fixed-orifice range of 0-to-2 through 0-to-40 GPH (liquid) and 1.5-to-5 scfm (gas). Highflow models have a variable orifice for flows from 0-to-1 through 0-to-30 gpn (liquid) and 1-to-100 scfm (gas). Both low and high-flow adjustable models have optional dials for local readout and handle pressures to 5,000 psig. The fixed-setpoint flowswitches target applications where simple flowswitch operation is required. It comes in six factory-preset steps from 0.1 to 1.5 gpm.
