The FSW530 Series flow switches are capable of detecting extremely
low liquid flow rates from 13 mL/minute up to 10 L/minute with a full
scale switch accuracy of ±1.0% or better! A wide variety of fluids may
be measured. Repeatable results are achieved using a patented
pelton-type microturbine wheel. This proven design has been
providing precision results since 1988 and has developed a well
deserved reputation for continuous operational service for many years
without failure. Because of the compact size and economical cost
of these products, the FSW530 models are suitable for a wide
variety of industrial, commercial, laboratory and OEM applications.
Some sample applications include high/low alarms for hydrocarbon
fluids, fuels, light oils, solvents, coolant, pesticides, mild acids,
alkalis, and de-ionized water. Either plastic or metal construction may
be selected.
