S-SERIES SPX SPT ISO 9 0 0 1 : 2 0 0 8 CERTIFIED COMPANY S-SERIES LOW FLOW METER INSTRUCTIONS LOW FLOW METER INSTRUCTIONS
GENERAL INFORMATION, FEATURES, SPECIFICATIONS These versatile impeller flowmeters are available in 3/8", 1/2”, 3/4”, and 1" nominal pipe sizes with female NPT threads (SAE optional). They employ jewel bearings to allow for very low minimum flow rates and superior life. With a body material of polypropylene, the SPX is an economical choice for metering water or low corrosion fluids.
INSTALLATION, CONNECTIONS INSTALLATION Piping Requirements. Standard fittings are female NPT. If the piping connected to the meter is metallic, care should be taken not to overtighten. Straight pipe of at least five diameters upstream of the meter is recommended. Vertical, horizontal, or inverted (lens down) installations are all acceptable. K-Factor. The meter is factory calibrated. The K-factor is found on the label on the meter body and must be input into the control/display for accurate reading.
REPAIR, MAINTENANCE REPAIR Rotor Replacement. There is only one moving part to this meter. The bearings are made of ruby, which rarely wears out or needs replacement unless they have been physically damaged by severe shock. The shaft is integrally molded into the rotor, and shaft and rotor are replaced as one part. (You may wish to replace the bearings, using the bearing removal tool, while the meter is disassembled for rotor replacement).
