A wide variety of installation fittings are available to assure compatibility with many commonly used plumbing materials: •Threaded galvanized •Copper sweat •PVC; CPVC •Iron •Steel The XLF flow sensor package is comprised of: •One (1) paddlewheel insertion type flow sensor element sized for the specified pipe diameter •One (1) installation fitting for the specified pipe type and size. How It Works The solid state paddlewheel flow sensor works on a simple, but precise, electro- mechanical principle. A magnetic rotor positioned in the flow stream spins past a solid state switch which in turn pulses a low voltage DC current proportional to the rate of flow. The rotor design ensures an accurate, repeatable output throughout the sensor's entire operating range with negligible head loss and no cavitation. Features & Benefits •Flow range; 0.3 ft/s to 20 ft/s •Low cost. •Low pressure loss. •Ease of installation and service. •Excellent resistance to corrosion and wear •High accuracy and repeatability. •Compatible with most types of piping materials – PVC, copper, brass, galvanized iron and steel. •Wide range of temperature pressure and flow characteristics. •Low voltage operation. •Tested to NIST standards (National Institute of Standards and Techonology).

Match this value against those in the MINIMUM and MAXIMUM FLOW column of the Flow Rate Range Table to find the corresponding installation Fitting Pipe Size. 3.Verify Temperature/Pressure Operating Range – the maximum operating pressure for the XLF series flow sensor is dependent on the measured fluid temperature and type of installation fitting. Refer to the Temperature/Pressure Graph for operating range. Refer to OPTIONS paragraph for applications requiring a higher temperature/pressure rating.
