These versatile impeller flowmeters are available in 3/8", 1/2”, 3/4”, and 1" nominal pipe sizes with female NPT threads. 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. The lens cover is available in a choice of materials: acrylic for visual flow indication of low-corrosive fluids; polypropylene when more corrosion resistance is needed. The standard rotor assembly is Kynar with tungsten carbide shaft (ceramic shaft optional). The O-ring is EPDM.
The SPT version offers greater chemical resistance with a Teflon body and cover, Teflon-coated Viton O-ring, and standard Kynar/ceramic rotor assembly (carbide shaft optional).
