    Since they come factory set to a specific set point, these switches are easier to install than adjustable flow switches. As flowing liquid pushes an internal piston, the switch reads the position of the piston to measure the flow. When the piston passes the set point, the switch actuates. They’re accurate in any mounting position.
    These switches are calibrated with and measure water accurately. They can also be used with other liquids by applying your liquid’s specific-gravity conversion factor to calculate the new set point.
    Choose a fitting material that is compatible with the liquid you intend to run through your line.

    PPS Fitting—Polypropylene and PPS fittings work with a wide range of chemicals. However, they can crack from impact or when overtightened.
    SPDT—SPDT (single pole, double throw) switches can either turn one device from off to on (normally open) or from on to off (normally closed).
